Background: The rates of return to play (RTP) after anterior cruciate ligament (ACL) reconstruction among professional and National Collegiate Athletic Association (NCAA) Division I athletes are well described in the orthopaedic literature. Less is known about these rates and risk factors for failure to RTP in Division II and III collegiate athletes. Purpose: To determine the RTP rate after ACL reconstruction among Division II and III collegiate athletes and to explore the factors associated with RTP. Study Design: Case series; Level of evidence, 4. Methods: Demographic and RTP data were retrospectively reviewed for collegiate athletes who underwent ACL reconstructions across high-risk sports over 6 years (2015/16 to 2021/22 seasons) at 5 northeastern NCAA Division II and III institutions. Clinical data collected included Patient Acceptable Symptom State (PASS) on the Knee injury and Osteoarthritis Outcome Score (KOOS) Sport and Recreation questionnaire, graft type, concomitant reparative surgery, reinjury, need for reoperation, and time to RTP and return to preinjury level. Participants completed the survey using a secure web-based questionnaire sent via email or over the telephone at a minimum 6-month follow-up. Descriptive frequencies were calculated for all documented variables, with chi-square and analysis of variance statistics used to assess for associations and significant differences between variables. Results: A total of 61 eligible student-athletes with primary ACL reconstructions were identified in this study period, and 40 knees were enrolled for analysis with a mean time from surgery to survey completion of 45.0 months. The overall RTP rate was 77.5% (31/40) at a mean of 10.1 months. However, only 50.0% (20/40) returned to their preinjury level of competitive play. There was a graft failure rate of 20% (8/40). Of the 32 athletes who did not reinjure their ACL, 81.25% (26/32) demonstrated a PASS on KOOS Sports and Recreation. Graft rerupture ( P < .001) and reoperation ( P = .007) had significant effects on rates of RTP. Concomitant procedures ( P = .010) influenced return to preinjury level of sports. Injury during the active season versus the off-season significantly influenced KOOS PASS status ( P = .038). Conclusion: This study demonstrated that the rate of RTP after ACL reconstruction in this patient population of Division II and III collegiate athletes was 77.5%, with only 50% returning to their preinjury level of competitive play. The graft failure rate in this population was 20%. Surgical factors, such as concomitant surgeries and reinjury of ACL graft, as well as athlete-specific data, such as injury in the off-season, were statistically significant negative influences on patient outcomes. Further research is needed to evaluate other potential factors that may play a role in RTP after ACL reconstruction.
