Rehabilitation duration and time of starting sport-related activities associated with return to the previous level of sports after anterior cruciate ligament reconstruction

Objectives: To determine predictors for return to previous level of sports after anterior cruciate ligament reconstruction (ACLR). Design: Cross-sectional; Setting: Athletic teams. Participants: Ninety-one athletes who had ACLR with hamstring-tendon autograft within 1-5 years participated in this study. Athletes indicated their sport participation levels, injury profile, rehabilitation duration, and time to start sport-related activities (running, cutting-pivoting) after ACLR. Athletes answered whether they returned to the same previous level of frequency, duration, and intensity of sports. Main outcome measures: Athletes' characteristics, injury and surgical factors, duration of post-operative rehabilitation program, and time to start sport-related activities after ACLR were evaluated by univariate logistic regression to determine predictors for return to previous level of sports. Results: Nine athletes (10%) returned to their self-described previous level of sports. Predictors for returning to previous level of sports were rehabilitation duration > 4 months (OR:6.78; p = .011), time to start running < 4 months (OR:8.62; p = .047) and cutting-pivoting < 6 months after surgery (OR:5.02; p = .030). Conclusion: Longer post-operative rehabilitation duration and time to start sport-related activities after ACLR predicted return to previous level of sports. Spending adequate time in post-operative rehabilitation program and time-based resumption of sports-related activities after ACLR might be key factors for returning to previous sports level.
