Olympics 2012: Treating Female Athletes

Olympics 2012: Treating Female Athletes

Stephanie Cajigal; Abigail K. Allen, MD

Editor's Note:
The 2012 Olympics represents a watershed for female athletes. Not only do women outnumber men on the US National Team, but for the first time, all participating countries will have sent female athletes to the competition. According to Abigail K. Allen, MD, a pediatric orthopedic surgeon at the Mount Sinai College of Medicine in New York City who manages many young athletes and Olympic hopefuls, the 2012 games are mirroring what has already been happening for years in the United States: An increasing number of women are becoming involved in sports. Medscape interviewed Dr. Allen about the challenges involved in treating female athletes.
Medscape: Studies show that female athletes are more prone to injury than male athletes. Can you elaborate on the specific types of injuries that women are more susceptible to?
Dr. Allen: Historically in sports, and even just several decades ago, sports were thought of as male activities; females didn't really play sports as much. But now, more and more females are playing sports. And more and more females are getting injured more commonly than males -- so they are not really created equal.
The most classic example of injury that female athletes are more prone to is the anterior cruciate ligament (ACL) tear. As females participate in sports more and more, they are getting the same injuries as males but at a higher rate. I think the incidence of ACL tears in female college soccer players is about 5%, which is pretty high; it's actually about 3 times higher than for male soccer players.
Medscape: What are some of the reasons why women are injured more often than men? How much of it relates to intrinsic biologic differences vs the way they're trained?
Dr. Allen: The reasons behind this are probably multifactorial, but it is thought to be potentially hormone related or anatomy related, because the notch in the knee is shaped a little differently in the female.
Differences in landing mechanics have been proposed as well. Females don't land the same way as males. They are thought to land a little more knock-kneed and not squatting down as much as how a male would land. Nowadays, a lot of the training programs focus on landing to try to decrease the incidence of ACL tears.
Medscape: Do you think training in landing mechanics is something that physicians should recommend, or is more research needed in this area?
Dr. Allen: This research is from a few years ago, so people are recommending it now.
Medscape: What research related to female athletes are you most enthusiastic about?
Dr. Allen: I've always been intrigued by the huge studies on improving landing mechanics and proprioception of the female athlete -- essentially, to get them to jump and land like a male so that they don't get ACL injuries as much. There are some studies that show that these training programs work.
Medscape: What research is lacking in this area?
Dr. Allen: You could think of this as a new frontier because females are just now becoming athletes and elite athletes. It is more common for females to play sports nowadays, even from childhood. Doing research, even if it is reproducing in a female population the same research that has been done in males in the past, would be beneficial. Research is lacking in the female population in general, because we haven't been playing sports as much as the male population until recent years.
Medscape: What should the medical community be doing to better cater to female athletes?
Dr. Allen: It goes back to the concept of being a team. It's partly about the physician gaining knowledge and trying to do things preventatively, but it's not just the role of the physician. It's also the athlete, the athlete's family, the coach, the athletic trainer, etc. It's about just being aware that females are athletes nowadays and that they can get the same injuries as men.
Also, the injury may not be the musculoskeletal injury that one always thinks of, such as a fracture or a sprain or an ACL tear. Especially in the female population, one should be aware of the Female Athlete Triad: disordered eating, amenorrhea, and resultant osteoporosis. The physicians (whether they be orthopedic or primary care physicians), the coaches, and the family should not just ask how Sally's ankle is doing but also make sure that they address her eating habits and ensure that she is menstruating relatively regularly.

LONDON (Reuters) Aug 01 - German beach volleyball player Ilka Semmler wears it on her buttocks - in pink. Swedish handball player Johanna Wiberg prefers it in blue from her knee to her groin. British sprinter Dwain Chambers has even worn it with a Union Jack design.
Athletic tape made in every color under the sun seems to be the latest must-have sports injury treatment at London 2012, where athletes may have been influenced by other big name tape fans such as Serena Williams and David Beckham.
Called Kinesio tape and developed by a Japanese doctor more than 30 years ago, the adhesive strapping is designed to provide muscle and joint support without restricting movement.
According to Kinesio's product website, it is also designed to be used with a particular taping technique - a skill practitioners need to learn on a special training course.
More than 4,000 people in Britain are now trained in the art of Kinesio taping, it says, and many of them look after some of the country's top sportsmen and women.
But does it really work?
Compared with the abundance of its use, rigorous scientific research on Kinesio tape is scant. But a handful of research papers suggest its ability to relieve pain or improve muscle strength is limited.
"Kinesio tape may be of some assistance to clinicians in improving pain-free active range of movement immediately after tape application for patients with shoulder pain," wrote scientists in one study published in the Journal of Orthopaedic and Sports Physical Therapy.
But the researchers added their findings did not support the use of Kinesio tape for decreasing pain intensity or disability in patients with shoulder problems.
In a review of all the scientific research so far, published in the Sports Medicine journal in February, researchers found "little quality evidence to support the use of Kinesio tape over other types of elastic taping in the management or prevention of sports injuries."
Kevin Anderson, managing director of Kinesio UK, which supplies the tape in Britain and trains people in how to apply it, says the scientific research has yet to catch up with what athletes and physiotherapists say about the tape's benefits.
"There's a lot more needed on the research side to confirm the positive results we're seeing so far," he told Reuters.
"There's nothing magical in the tape, it certainly can't improve your performance or make you into Superman, but the way people use the tape is to lift the skin, reduce the pressure and that helps relieve pain and swelling."
Whatever the science, German beach volleyball player Sara Goller sported two long pink strips of the tape on her left leg during matches on Tuesday, while her partner Laura Ludwig had two vertical blue strips on her stomach.
"I don't really mind the color, it's more about what it does. It can release or put tension on a muscle, it depends on what you want. Our physio is really good at doing it," Goller told Reuters.
John Brewer, a professor of sports science at Britain's University of Bedfordshire, remains doubtful.
"As a scientist, I'm still not convinced about the underlying mechanisms," he told Reuters, voicing skepticism about the supposed "lifting" effect and the ability of tape applied to the skin to enhance the performance of muscles deep inside the body.
Steve Harridge, a professor of human and applied physiology at King's College London, said many athletes appeared to be wearing tape even when they had no injury, possible hoping for some preventative or enhancing effect.
"It may be a fashion accessory, and it may be just one of those fads that come along from time to time, but to my knowledge there's no firm scientific evidence to suggest it will enhance muscle performance," he told Reuters.
Both scientists agreed, however, that there may be a benefit, in the form of the placebo effect.
"The fact that athletes think it's going to do them some good can help in a psychological way," said Harridge.
An effective placebo, Brewer said, "could make all the difference between success and failure."

On-the-Spot Treatment of Sports Injuries

An Expert Interview With Margot Putukian, MD

Carol Peckham; Margot Putukian, MD


 
Editor's Note:
As part of Medscape's coverage of the 2012 Summer Olympics, we interviewed Margot Putukian, MD, Director of Athletic Medicine and Head Team Physician for Princeton University. Dr. Putukian is a former President of the American Medical Society for Sports Medicine (AMSSM) (2004-2005) and is currently President of the AMSSM Foundation. She also serves on the Ad Hoc Sports Science Safety Committee Task Force on Clinical Medicine for the American College of Sports Medicine. Dr. Putukian has been a leader in research on concussion, with involvement in the Team Physician Consensus Statements, the National Athletic Trainers' Association Position Statement, as well as the Zurich International Consensus Conference on Concussion. She has served on the US Lacrosse Sports Science & Safety Committee since 2004 and in 2009 was named Chair. She is also involved with the National Football League Head, Neck & Spine Committee, serving as Chair of the Return-to-Play Subcommittee. In this interview, Medscape asked Dr. Putukian about on-the-spot treatments for injuries during competitive events.
Medscape: What are common on-the-spot treatments for injuries to the lower extremities? And what are the criteria for allowing an athlete to return to competition after such injuries?
Dr. Putukian: Obviously it depends on what the exact injury is, but most acute lower extremity injuries are treated on the spot with ice, splinting, or immobilization, and, as long as there is no contraindication, nonsteroidal anti-inflammatory medications for pain. Additional diagnostic testing, such as an x-ray or other studies, may be helpful in determining the extent of injury, and the splinting or immobilization necessary, again, depends on the injury. For an acute ankle sprain, where the ligaments on the outer aspect of the ankle are torn, for example, it may be useful to provide some support (splinting and protection of the ankle as necessary), apply ice and compression, and elevate the ankle or leg. X-rays may be indicated to exclude fracture, and if there is no fracture, then the rehabilitation is to slowly restore range of motion, strength, and proprioception. It is often necessary to modify activities, such as having the athlete swim instead of run, or use other modes of exercise that do not interfere with the rehabilitative process. The criteria for return to play (RTP) after such injuries is restoration of full range of motion, full strength, and then assessment to make sure that functional activities (eg, running, jumping, cutting side to side) are back to an acceptable level where the athlete can participate without significant risk for additional injury. The RTP is typically gradual and slowly increases both the demands and the level of competition of the specific athlete.
Medscape: What about upper extremity injuries?
Dr. Putukian: This is the same as with lower extremity injuries. The only difference is that it's typically easier to immobilize and/or modify activities because weight bearing is not an issue.
Medscape: What protections are in place to prevent, diagnose, and treat cardiac arrest in intensive athletes?
Dr. Putukian: This depends on the age we are discussing. For youth athletes, we have the preparticipation physical examination, which should include and endorse the American Heart Association (AHA) 12-Element recommendations for preparticipation cardiovascular screening of competitive athletes. These recommendations address personal history, family history, and physical exam findings.[1] The PreParticipation Physical Evaluation (PPE) monograph,[2] currently endorsed by all major sports medicine organizations, also includes these 12 questions, so our college and youth participants have reasonable screening. Athletes who give even 1 positive response to these questions should have appropriate evaluations to exclude cardiac disease. Older athletes should have a physical examination that assesses cardiac risk factors and, in my opinion, should include the AHA 12 questions as well. An ECG and cholesterol screening might also be indicated.
Treating cardiac arrest should ideally include having available personnel certified in cardiopulmonary resuscitation and knowledgeable about the use of an automated external defibrillator (AED). Ideally, early access to defibrillation is defined as having the AED and personnel within 3-5 minutes.
Medscape: What is being used now to immediately stabilize patients who experience concussion?
Dr. Putukian: There is a spectrum of concussion, so this is difficult to answer. On the one extreme are athletes who present with symptoms that cannot exclude more serious brain injury or cervical spine injury; they should be spine-boarded and transported to an emergency center with facilities and personnel to handle cervical spine and brain injuries. On the other extreme are athletes with short-lived symptoms of concussion, with no evidence or concern for complications or more serious brain injury. These athletes improve within minutes, and the immediate concern is to make sure they do not return to activity until they are evaluated by a healthcare provider experienced in evaluating and managing concussion. Athletes should also be told to remain out of physical activity and minimize cognitive activity (eg, avoid texting, video games, computer use) until they are evaluated. Athletes should be given information on what to watch for (symptoms or signs of deterioration) and what to avoid, such as aspirin and alcohol, as well as when they should be seen for follow-up.
Medscape: What about patients who experience hyperthermia? Can they be treated immediately and in time to return to competition?
Dr. Putukian: Hyperthermia is a general term that includes a spectrum of heat-related illness that includes heat cramps, heat syncope, heat exhaustion, and exertional heat stroke, the most extreme and sometimes fatal form of heat-related illness. It is important to define the extent of thermal injury that is occurring because treatment can be different. A lot can be done to prevent heat-related illness, including hydrating, avoiding exercising in the heat and humidity (avoid the hottest part of the day), acclimatizing to the heat, and having an emergency action plan that incorporates guidelines for avoiding heat injury. When heat injuries do occur, it is important that they are assessed by reliable measures (rectal temperature), that the athlete is moved to a cool/shaded area, and that immediate cooling occurs, ideally with whole-body ice water immersion. If possible, the athlete should be provided with oral rehydration. RTP after heat-related illness depends on the extent of the thermal injury. For heat exhaustion, the recommendation is to wait at least 24-48 hours before returning and at least a week for exertional heat stroke. Each situation must be considered individually, as several factors should be considered in the RTP decision. The Korey Stringer Institute has a lot of good information related to avoiding hyperthermia, treating it, and RTP.
Medscape: How are electrolyte and dehydration deficiencies recognized and dealt with during events? Specifically, what happens to athletes who experience muscle cramping? Can they return to competition?
Dr. Putukian: Electrolyte imbalances and dehydration are recognized by healthcare providers during events in various fashions. Dehydration can be assessed by measuring blood pressure and pulse after an athlete is lying down for 2-3 minutes, then standing up for 2-3 minutes ("orthostatics"). Changes in blood pressure and pulse are then evaluated with this change in position. If there is a drop in blood pressure or an increase in heart rate when going from the lying to standing position, the athlete may be dehydrated.
Electrolyte abnormalities can be evaluated using various methods and are measured with a portable unit that takes a small amount of blood and provides a result. Electrolytes are most often measured during endurance road-running events. They are not typically measured in organized sports such as soccer, football, or other events that are not endurance-type activities.
Muscle cramping can occur if an athlete has electrolyte deficiencies or is dehydrated. Typically in organized sports, such as soccer and football, these can be treated by stretching, icing, replacing fluid and salt balance, and decreasing activity; often these athletes can return to activity. It may be more difficult for athletes participating in endurance sport events to return to activity immediately. It is important to make sure that they are not suffering from sickle cell crisis, where cramping occurs that typically is not associated with muscle contractions. Exertional sickling can be associated with rhabdomyolysis (muscle breakdown) and death and should be treated as an emergency. Screening for the presence of sickle cell trait can be useful, and knowing which athletes are at risk for heat-related illness is also important.

What Have the Olympics Taught Us About Sports Medicine?

What Have the Olympics Taught Us About Sports Medicine?

Medscape: You were a NCAA Division I swimmer. What insights does an athlete at that level bring to the practice of orthopedics?
Dr. Frey: It helps in understanding not only the type of injuries they have, but also their motivation and desire to get back to the team after an injury. They're like injured warriors. At Walter Reed National Military Medical Center, one of the first things you will hear from even the most injured troops is their desire to get back to their unit.
It is similar with an athlete. It is such a part of their identity and how they define themselves that their first motivation is to get back to the team or get back to the sport, as the case may be. They don't want to hear, "Maybe you shouldn't swim again," or "Maybe you shouldn't do this again," or "Why don't you take 6 months off?" To an athlete, that is code that that person who is speaking has never played sports or is not an athlete.
Carol Frey, MD
You need to understand the motivation -- the core personality of an athlete. People don't become athletes as adults. As a swimmer, for example, I became very competitive when I was about 9 years old, and today, it begins at 7 years. People specialize much earlier, and when they do, it becomes much more than physical.
Outsiders ("civilians") look at athletics as something that is just physical. They think, "They're naturals, they work out, they're strong, that's all it is." It's more than that. A lot of people are strong and a lot of people work out, but only a few will make it to the Olympics. The difference is heart; discipline; dedication; and, of course, genetics. Athletes drop out of competitive sports for many reasons. They may lack the heart or the discipline, or they get injured.
Medscape: I talked to an orthopedist who works with soccer teams, and he mentioned the same thing: the underpinning of the motivation of the athletes and that, when injured, they want to get back to the game or to the team. One question that it raises is, do you have a responsibility to the athlete that extends beyond the team? How do you manage being pulled in different directions?
Dr. Frey: You don't do anything that is dangerous or bad for the athlete. As a physician, I will tell you the most difficult thing to do is not the diagnosis or the surgery; it's the rehabilitation and the return to the sport. It helps being a former athlete. I'm not saying that nonathlete physicians can't do it, but it takes more work and you need to invest more time to get to know your patient -- that is the first thing.
The second thing is that there are ways to do rehabilitation without the athlete losing strength or no longer being part of the team, and ways to do it without further injuring the athlete. In my opinion, many physicians do not know how to properly rehabilitate an athlete.
For example, let's say the athlete has a stress fracture. The easy way to treat it is to put the athlete in a cast and tell him or her not to do the sport for 6 months. It will work. The patient will get better, but there is another way. Immobilize the athlete for a couple of weeks, and then kick-start the process by getting the athlete in a pool doing really good pool exercises, with high kicks, side steps, a noodle workout, and core work. Get the athlete doing Pilates, using the core ball, and working on core strength and upper body strength. Use physical therapy to your advantage, and even do deep soft-tissue work to get the muscles loosened up.
It takes a lot of time to get to know the patient and explain and prescribe these exercises. Not every doctor has the time or the motivation. I'm not saying that the physician is lazy. Some of them just don't know. Some know but don't quite trust the method because they haven't done it enough. Why take a chance? The athlete might injure himself while he is in the pool.
It takes a level of knowledge and specialty to know how to rehabilitate a patient. It is the more difficult part of orthopedics. It certainly takes the longest. You really have to listen to the patient. You really have to get to know the patient and the patient's motivation.

Resisting the Pushes

You also have to be immune to the pushes. The coaches and the parents get involved, so you have to handle them as well. When you have an athlete at that high a level, especially Olympic level, division I level, or even club level or high school varsity, the parents and coaches can be more difficult than the athletes.
Furthermore, other athletes may treat the injured player differently. He or she is not ostracized, but is not quite a member of the team. The injured athlete is sitting on the bench or in the stands, not playing and not functioning as part of the team.
You have to be confident, too, because some of those coaches are pushy and they have their own ideas. They also have the ear of the athlete more than you do. The physician comes in as a satellite member of the team. You only see the athlete when the athlete is injured. The athlete sees the coach every day. You have to convince the coach to be on your side, as part of the rehabilitation program. You have to get the coaches on board.
Medscape: I can see how it would be a very difficult challenge, particularly the professional one.
Dr. Frey: Yes, and the parents have so much invested. By the time a kid becomes an Olympic athlete -- swimmer, tennis player, volleyball player -- think of the tremendous amount of time and money they have invested: the 5-AM wake-ups, the meets, the $300 swimsuits, and the private coaching. It is a very expensive enterprise to produce an Olympic athlete.
When a child gets injured, the parent doesn't just say, "My poor son. He isn't going to be able to realize his potential," but also, "Oh my God, I wasted all that money." All these thoughts are going through their heads. "You can't quit now. This is getting you into Stanford."

Injury Patterns in Swimmers

Medscape: Could you discuss injury patterns in swimmers?
Dr. Frey: It has been said that at some point in a swimmer's career, if the swimmer is at a competitive level, more than 80% will have a shoulder issue. It won't necessarily mean that the swimmer will have to stop swimming, but it is very common to have a shoulder issue. So much of the stroke is built into the stability and position of the shoulder.
The shoulder is a unique joint and has more range of motion than any other joint in the body, so it is not hard to imagine how it can get injured. It is very mobile, and in swimmers, it tends to get almost hypermobile because of the mechanics of swimming. Swimmer's shoulder is an inflammation around the shoulder unit, and the person who is most at risk for this type of injury is a swimmer with a more relaxed or more hypermobile shoulder because his shoulder can assume more complex and varied positions.
It is not unusual for a competitive swimmer who swims up to 20,000 meters a day, 6 days a week and then does dry-land exercises, too, to do about 4000 strokes per shoulder per day. The rotator cuff and biceps tendon are commonly inflamed. The cause of swimmer's shoulder is a combination of this hypermobile shoulder and problems with swimming technique.
The technique that leads to swimmer's shoulder is often related to the way the swimmer's hand enters the water. Swimmers enter the water at midline or off to the side a little bit. We call it "crossover." He enters the water, and then his hand crosses over his body a little bit. People with swimmer's shoulder have a little more of that crossover and may enter the water completely thumbs down. That puts a little too much torque on the shoulder.
These are some of the things you can look for that might cause some repetitive trauma, malpositioning, or mechanical problems to the shoulder. It requires an analysis of the swimming technique.
Medscape: When you come across a situation like that -- let's say you find it in an athlete who is in a competitive situation -- what can you do?
Dr. Frey: The main thing to do is change the swimmer's technique. Technique is one of the reasons that speed has increased so much. We also have kids who are just getting bigger, and that helps in swimming -- big feet and big hands. Having swimming coaches who really work on the mechanics of the stroke has improved swimming tremendously in the past 20 years.
You can look at the swimmer's mechanics and change the position of the swimmer's hand as it enters the water, with less torque on the shoulder. The swimmer can enter just short of midline.
That is just one example, but you need to look at the mechanics first of all and change the mechanics because you can do that, much like a weightlifter can change the position of his hands on the weight bar. You want the muscles of the shoulder to work through a stable arc. You don't want an unstable shoulder, with too much motion.
The key remedies for swimmer's shoulder are physical therapy, working on mechanics, and working on core strength. Why core strength? Core strength allows the swimmer to streamline well, and in swimming, streamlining is making sure you don't wobble side to side.
Think of the midline or the lane line. You want the body to stay on that lane line. It's like an airplane landing. Side-to-side movement, also called "body roll," can be reduced by core strengthening. Core strengthening will also put the shoulder in a better position. The exercise ball is really good for that.
There are so many good exercises for swimmers, such as the supine back extension stretch, that can be done with a core ball. Another exercise is called "Superman." Most swimmers know what a Superman is. You lay on the core ball face down, your opposite leg goes up from your arm, and you go back and forth doing a back extension.
Push-ups and trunk rolls can be done on the core ball. The upper and lower abdominal muscles must be kept very strong. This will stabilize the pelvis, stop the lateral trunk movement in the water and stabilize the shoulders and trunk. This will make the swimmer more powerful and less apt to get injured. Physical therapy and looking at mechanics will solve 90% of the problems with swimmer's shoulder.

Injuries in Practice

Medscape: What if you are in a situation where somebody is injured during competition? Do Olympic swimmers develop swimmer's shoulder during competition?
Dr. Frey: Most injuries happen during practice, when athletes are swimming 20,000 meters. They don't swim 20,000 meters during a competition; they swim 200 meters. I can't think of an example where an injury has happened during competition. That is how rare it is. The injuries at competition are accidents, not overuse.
Medscape: You were a Division I swimmer. Did that lead to your medical career, or were you already embarked on it?
Dr. Frey: I probably always wanted to be a doctor. I may have been brainwashed a little bit by my grandmother, who was a medical missionary. She used to say, "You would be a great doctor," so I always had it in the back of my mind.
What solidified orthopedics, and this is probably true of a lot of orthopedic surgeons, was that I had an injury in college. I was a swimmer but I also played volleyball, having grown up at the beach, and during a pick-up volleyball game right after coming out of the pool, I tore my anterior cruciate ligament.
My injury didn't hurt my swimming. I actually rehabilitated in the pool really well. Just going through that -- and I was at Stanford University at the time -- I got to know orthopedics and orthopedists, and I thought it was a brilliant career. The patients you see are wounded, not really sick, and they get better. If you do the right thing, they get better in 6 or 12 weeks. Very few specialties in medicine are like that. There is instant feedback that makes orthopedics a very positive career.
Medscape: You follow the Olympics swimming very closely. Do you follow the rest of the Olympics, and do you have any general observations about orthopedics in the Olympics?
Dr. Frey: My husband is one of the Olympic doctors. He is an orthopedic surgeon, as well. To be an Olympic doctor, you have to train for 2 weeks. You have to leave your practice, go to Colorado Springs, move into a dormitory, and train with the Olympic people and personnel to learn how to treat the athletes. You get to know their specific trainers. These are not random doctors. They are selected by the Olympic committee.
There are other international games that take place before the Olympics. For example, the US volleyball team was in Bulgaria 2 weeks ago, and my husband was with the US volleyball and weightlifting teams. Each sport has at least 1 physician, and often more, who travel with those teams when they go to the international qualifying games leading up to the Olympics.

Developments in Training

Medscape: Are there new things in swimming that orthopedic physicians would like to hear about? Are there new developments coming down the line?
Dr. Frey: The developments have to do with training. Everybody wants to know what makes Michael Phelps or Ryan Lochte so good. Why are they so spectacular? There is a lot of talk about how big Phelps' hands and feet are. You can't do anything about that. That is a genetic lottery.
One of the things that has come out of the Olympics happened when the East Germans came on the scene. It was in Munich. Everybody disapproved of their methods. They looked for markers -- physical traits -- and funneled kids into sports really early, like at 5 years old, on the basis of these traits. This information came out when the Berlin Wall came down and the Cold War ended.
They were the ones who started the weightlifting and emphasized dry-land exercises for swimmers. When I was swimming, which was in the 1970s, we weren't doing much dry-land work, and when we saw how big and powerful the East Germans were, that was a turning point for swimming. Maybe there was a lot more going on behind the scenes, but we started weightlifting and realizing it was important to have strong upper-body muscles, a strong trunk, and core strength.
The practice of doing genetic testing and picking kids on the basis of genetic traits sounds awful to the sensibilities of the Western world, and some of the books also show that the East German athletes were using steroids and strength-enhancing drugs. It wasn't all dry-land work, as it turns out.
I have a true story about swimming against the East Germans. The first time we saw them, upon walking into the women's dressing room with the showers in our peripheral vision, and just seeing them from behind -- their backs, their shoulders -- and hearing their voices, I walked out and said, "Are we in the boys' locker room?" I was not small. I was 5' 11" and 165 lb. I was considered big in those days, and those girls were bigger than me.
Medscape: As I think back on that, the East Germans were notorious.
Dr. Frey: They were, but we can learn from them. We learned that we needed dry-land exercises, that we couldn't just swim in the pool 20,000 meters. Even today, we are learning new training techniques. When you pick up a magazine, such as Triathlon or Outside, which profiles a lot of athletes, their nutrition gets as much publicity as anything.
Ryan Lochte is famous for saying that he eats French fries and hamburgers all the time, but in a recent edition of Outside magazine, he said that he has changed his diet. One US decathlon player spent half an article giving recipes for highly nutritious meals. Nutritional status, flexibility, and body work have become much more important in our training. It is not just how many miles you log or how many laps you swim anymore.

The Personality of an Athlete

Medscape: Any final words?
Dr. Frey: What we need to understand about athletes is that so much of their personality is being an athlete. All of their spare time has been devoted to their sport. These people essentially gave up their youth to train and watch their diets, to go to meets, and to try to prevent injuries. To help them as physicians, we have to let them know that we are part of their team and will work to keep them in the game. I know that's a cliché. We don't want them to play so that they injure themselves, but 99% of the time, there is a way to keep them in the game.
When athletes get injured, they need to know they are on the injury list. Most people at an elite level have had an injury at some point in time and have lost a week or more of playing time or practice. It is part of getting to that level. I can't think of one player who hasn't had an injury at some point that required an orthopedic surgeon, a physical therapist, or time off from play.
If you can manage it, keep them in the game even when they are injured, by seeing a physical therapist and getting them in the pool doing pool exercises, side steps, and Pilates exercises, which were actually designed for injured warriors.
Remember that mentally, this is their identity. They have given up so much, and you have to keep them positive.

Abstract

Anterior cruciate ligament injuries in skeletally immature patients usually involve tibial bony avulsion fractures rather than the midsubstance tears usually observed in adults. Several surgical techniques have been reported to provide stable fixation and avoid physeal injury in this pediatric population. The authors propose a novel, reproducible surgical technique using bioabsorbable anchors to obtain biomechanical stability and minimal physeal or articular cartilage damage.

Anterior cruciate ligament (ACL) injuries in skeletally immature patients usually involve tibial bony avulsion fractures rather than the midsubstance tears usually observed in adults. Anterior cruciate ligament avulsion fractures are more common than midsubstance injuries in the skeletally immature population due to the relative increased strength of the ligament compared with the developing bone and growth plate. The avulsion usually occurs at the tibial rather than the femoral side.1,2
Although several techniques to fix these avulsion injuries reportedly provide stability and reliable clinical outcomes, physeal damage is a major concern. This makes the surgery difficult, especially when comminuted fragments are present.2–5 The authors propose a simple surgical repair technique that can help avoid physeal damage and obviate additional procedures or procedure-related morbidity.

Case Report

A 9-year-old girl with no significant medical history sustained a right knee injury after falling from a trampoline a few days prior to presentation. Neither she nor her parents were able to recall the exact mechanism of injury, but she reported a twisting sensation of her right leg on contact with the ground. Physical examination showed a moderate knee effusion and tenderness over the anterior aspect of the knee. Lachman testing was positive; formal pivot shift testing was deferred secondary to patient guarding.
Radiographs revealed isolated avulsion and elevation of the tibial attachment of the ACL and open physes (Figure 1). The T1-weighted magnetic resonance sequence showed displacement of the distal avulsed ACL fragment (Figure 2). No evidence of meniscal injury or associated chondral lesions was observed. The patient and family consented for arthroscopic fixation of the injury.

Under general anesthesia, the anterior drawer sign was positive. The patient was placed in the supine position with the right knee held in a leg holder. Initially, arthroscopic examination through anterior portals was blocked by a displaced osteochondral fragment attached to the ACL (Figure 3A). Viewing from the anterolateral portal, a probe was introduced from an anteromedial portal to attempt fragment reduction.

Once a clear visual field was obtained with appropriate reduction, a Crescent Suture Hook on a Spectrum suture delivery system (ConMed Linvatec, Largo, Florida) was introduced from the anteromedial portal to pass through the substance of the ACL proper. A #1 PDS suture (Ethicon, Inc, Somerville, New Jersey) was then passed through the ACL tissue and retrieved from the accessory anterolateral portal. This step was repeated to create a 4-strand grasping construct. The 4 strands of suture controlling the ACL were tensioned from both anterior portals and then threaded into a PushLock anchor (Arthrex, Inc, Naples, Florida) (Figures 3B, C). Figure 4 shows the 4-strand suture configuration after appropriate suture shuttling through the ACL.

The PushLock anchor was introduced from the anteromedial portal while tensioning the other side of the suture material (Figure 5A). Finally, the anchor was fixed into the intact osteochondral junction, away from the avulsion fracture site and the medial and lateral menisci on either side, and the reduction was completed (Figure 5B). Figure 6 shows the final location of the suture fixation anchors. Gentle Lachman and pivot-shift tests were normal after fixation.

Postoperatively, a hinged knee brace was used with the knee in full extension for 6 weeks, with gradual increases in ROM. A transition from partial to full weight bearing was also initiated, and continuous passive machine and careful guided physical therapy were also started. At 12 weeks postoperatively, the brace was removed and full ROM and weight bearing were allowed. At 7-month follow-up, the patient had returned to preinjury level of sports and activity. No evidence of growth disturbance was noted on subsequent imaging at 24-month follow-up.

Technical Pearls and Pitfalls

Pearls

  • ▪ As with all procedures in skeletally immature patients, a spinal needle inserted percutaneously may be used to confirm on static fluoroscopic imaging the precise localization of the undulating physes about the knee and to ensure all-epiphyseal fixation.
  • ▪ Both anterior portals must be of sufficient height to properly visualize the fracture donor site, as well as for ease of fragment and ligament reduction.
  • ▪ Consider regional anesthesia techniques in conjunction with a trained anesthesiologist to afford adequate perioperative pain control.
  • ▪ Patients’ and families’ expectations must be carefully discussed preoperatively; although minimized with this technique, the potential of physeal damage must be discussed.
  • ▪ Consider slightly recessing the bony fragment in place by approximately 1 to 2 mm at the attachment site.
  • ▪ It is important to visualize the ACL and fixation through the entire ROM to verify no movement at the repair site, no impingement, and precise anatomic reduction of the ACL.

Pitfalls

  • ▪ A careful diagnostic arthroscopy must be performed to rule out associated injuries and remove any hemarthrosis or clot that may obscure adequate visualization.
  • ▪ If significant time has passed between injury and planned fixation, intraoperative assessment must be performed for arthrofibrosis that might compromise surgical outcome and postoperative ROM.
  • ▪ Entrapment of the menisci, particularly the anterior horns, may hinder adequate reduction.
  • ▪ Likewise, the transverse meniscal ligament may block full reduction back into the bed onto the tibial plateau and must be carefully freed from the tibial avulsion site.
  • ▪ Overly aggressive reduction maneuvers or repeated attempts at grasping suture passage may further fragment the avulsed bony tissue.
  • ▪ Timing of the surgical procedure, as with all forms of ACL repair, is critical; arthrofibrosis in an acute inflammatory period may necessitate lysis of adhesions or challenge postoperative ROM.
  • ▪ A detailed and individualized physiotherapy program must be established and reviewed with the physical therapist and with the patient and family.

Discussion

The treatment of ACL avulsion injuries in skeletally immature patients is controversial, and a major concern exists for potential physeal damage.4,6,7 Although reports have examined modern fixation methods, these techniques include risks to the open physis.3,6 Bonin et al3 recommended that the smallest fixation device available should be chosen to avoid physeal damage; the authors suggested removal of the device once fracture consolidation occurred. Ahn et al8 described a new technique of a physeal-sparing all-inside repair. Although it has merits in terms of grasping small fragments in skeletally immature patients, it requires large suture hooks to grasp the ACL and peripheral soft tissues, and this method has concerns regarding the integrity of the transverse ligament.
Other alternative treatments exist. A trial of extension casting in an attempt to reduce the avulsed fragment through nonoperative means may be reserved for minimally displaced fragments that demonstrate acceptable reduction after cast placement. Arthroscopic reduction with crossed suture–bridge fixation of the tibial spine fracture may be performed with a cannulated drill bit and ACL targeting guide.
After establishing a tibial bone tunnel, a Prolene suture (Ethicon Inc) may be used to shuttle #2 FiberWire sutures (Arthrex, Inc) to the posterior aspect of the fracture fragment. A Scorpion suture passer device (Arthrex, Inc) may be used to then pass the suture through the ACL at its insertion point onto the avulsed fragment. A Bunnell-type suture weave across the footprint of the avulsed fragment with both suture limbs may be used to reduce the avulsed fragment into the donor site and be tied over the bone bridge at the anterior aspect of the tibial epiphysis.
Zhao et al5 used a figure-of-8 suture technique with a transpatellar tendon portal: a 45° curved cannula (ConMed Linvatec) was used to pass Ethibond suture (Ethicon, Inc) for ligament fixation. Hsu9 used an Acufex ACL drill guide (Smith & Nephew, Andover, Massachusetts) and a straight or curved Penetrator (Arthrex, Inc) to tie suture strands over a bony bridge or button.
Several other fixation methods have been reported with satisfactory outcomes. Generally, Kirschner wire or screw fixation can fix avulsed bony fragments.10–13 Arthroscopic reduction and antegrade cannulated screw fixation through a high anteromedial portal or a pull-out suture via a tunnel drilled from the proximal tibia remain popular fixation strategies.11,14–16
However, disadvantages include possible further comminution of fracture fragments during insertion, possible impingement of the screw head during knee extension, and the requirement of a secondary procedure for screw removal.11 Suture cerclage is also used as alternative method.6,9 Eggers et al7 support this technique because, in their experience, suture fixation provides more biomechanical strength than screw fixation.
A similar technique to the current authors’ bioabsorbable suture anchor method was reported by In et al.17 This study used a 2.9-mm arthroscopic drill (DePuy Mitek, Raynham, Massachusetts) followed by Bioknotless and Panaloc anchors (DePuy Mitek) to secure the PDS suture for ligament repair.
The current authors’ repair technique has several advantages over those described in the study of In et al.17 It uses more suture strands to capture and control the ACL proper and to provide better mechanical strength of the repair site, it obviates the need for an additional portal and larger cannula for suture hook introduction, and it easily controls the tension of the ACL on each side of the tibial avulsion fracture site.

Conclusion

This article described a novel technique for the fixation of ACL tibial avulsions in a skeletally immature patient population. This simple suture fixation technique is easily reproducible and minimizes risks to the immature physis. It should be formally compared with other fixation strategies in future clinical studies, and it may be a viable alternative in skeletally immature patients. Further studies regarding biomechanical strength of the fixation are also needed before widespread application.

Abstract

Background: The patellar tendon has limited ability to heal after harvesting its central third. Platelet-rich plasma (PRP) could improve patellar tendon healing.
Hypothesis: Adding PRP to the patellar tendon harvest site would improve donor site healing and improve clinical outcome at 6 months after anterior cruciate ligament (ACL) reconstruction with a patellar tendon graft.
Study Design: Randomized controlled trial; Level of evidence, 1.
Methods: Twenty-seven patients were randomly divided to receive (n = 12) or not receive (n = 15) PRP in the patellar tendon harvest site during ACL reconstruction. The primary outcome was magnetic resonance imaging (MRI) assessment of patellar tendon healing (gap area) after 6 months. Secondary outcomes were questionnaires and isokinetic testing of ACL reconstruction with a patellar tendon graft comparing both groups.
Results: Patellar tendon gap area was significantly smaller in the PRP group (4.9 ± 5.3 mm2; 95% confidence interval [CI], 1.1-8.8) than in the control group (9.4 ± 4.4 mm2; 95% CI, 6.6-12.2; P = .046). Visual analog scale score for pain was lower in the PRP group immediately postoperatively (3.8 ± 1.0; 95% CI, 3.18-4.49) than in the control group (5.1 ± 1.4; 95% CI, 4.24-5.90; P = .02). There were no differences after 6 months in questionnaire and isokinetic testing results comparing both groups.
Conclusion: We showed that PRP had a positive effect on patellar tendon harvest site healing on MRI after 6 months and also reduced pain in the immediate postoperative period. Questionnaire and isokinetic testing results were not different between the groups at 6 months.

CBO estimates repeal of Affordable Care Act would increase spending by $109 billion

  • July 26, 2012
Two analyses from the Congressional Budget Office and the Joint Committee on Taxation released in light of the recent Supreme Court decision to strike down the state-mandated Medicaid expansion provision in the Patient Protection and Affordable Care Act estimate the act will save $84 billion over the next decade, while repealing the act under recently passed legislation would increase federal spending by $109 billion.
Insurance provisions of the Patient Protection and Affordable Care Act (PPACA) have reduced spending from a projected $1,252 billion in March down to $1,168 billion, the report stated.
H.R. 6079 passed by the House of Representatives on July 11, would increase the net deficit of the federal budget by $109 billion, according to an open letter to current Speaker of the House of Representatives John Boehner.
The decrease in federal spending is attributed to lower than expected Medicaid enrollment resulting from new requirements outlined in the Supreme Court PPACA decision. The Court struck down a provision requiring that states expand eligibility for Medicaid to qualify for continued federal funds in any part of their Medicaid program.
Since every state is no longer required to expand Medicaid, the budget office estimates that, in 2022, Medicaid and the Children’s Health Insurance Program will cover 6 million fewer people; 3 million people will shift to private health exchanges and 3 million will remain uninsured, according to the the report. Of the people who were covered under the new Medicaid requirements in states not expected to expand the programs, nearly two-thirds will have income considered too high to qualify for private exchange subsidies, while one-third will have income high enough for the subsidies.
“In addition, those who become eligible for subsidies will have to pay a portion of the exchange premium themselves, which will affect their decisions about whether to enroll in the exchange,” the report stated.
