A total of 165 meniscal tears were observed in 140 participants. A meniscal tear was observed in 39.6% (140/353) of cadets who sustained an ACL tear at arthroscopy (95% confidence interval [CI], 34.5%-45%). Of the 140 cadets who sustained meniscal tears, 68 had isolated medial meniscal tears, 47 had isolated lateral meniscal tears, and 25 had medial and lateral meniscal tears.
No significant difference was found between acute vs delayed treatment and the incidence of meniscal tears.
Compared with other sports, wrestling and volleyball had the highest incidence of concomitant meniscal tears at 77% and 125%
Because of the nature of the service academy and the process by which injuries are documented, we are confident that we identified all ACL injuries and did not underreport rates. Most importantly, 352 of 353 ACL injuries underwent ACL reconstruction, allowing us to identify all meniscal tears. Despite our large and well-documented cohort, our rates of concomitant meniscal injury based on laterality, level of sport, mechanism of injury, timing of treatment, and sex did not reach statistical significance.
Nice paper.
