ObjectivesThe psychological and physical recovery after anterior cruciate ligament (ACL) reconstruction (ACLR) may or may not occur in parallel. A common scenario is the uninformed athlete who lacks awareness of physical deficiencies and returns to sport prematurely. There is increasing evidence that most patients do not meet return to play criteria at 6 months and physical deficits may still persist 1 year after surgery. We hypothesise that a Quality of Movement Assessment for Return to Sport (QMA-RTS) testing programme may have a negative impact on athletes’ perception of psychological readiness to return.MethodsA total of 30 athletes who had ACLR and underwent the QMA-RTS 4–10 months after ACLR were recruited. They were randomised to one of two groups that both completed a baseline ACL Return to Sport after Injury (ACL-RSI) scale before their QMA-RTS appointment. In the intervention group, participants completed a second ACL-RSI after the QMA-RTS. In the control group, participants completed their second survey before the session. The mean difference in scores between the two groups was compared using an independent samples t-test.ResultsThe groups were balanced for sex (9/15 female), mean age (16 years) and average time since surgery (6 months). The baseline ACL-RSI scores were not statistically different between groups (4.6 (95% CI −10.6 to 19.8), p=0.54). In the controls, there was an increase in scores (+4.4) between the first and second surveys, while there was a decrease in the intervention group (−3.4). This difference between groups was not statistically significant (7.8 (95% CI −1.7 to 17.3), p=0.10).ConclusionsThe QMA-RTS programme did not significantly reduce patients’ mean scores on the ACL-RSI compared with controls. The limited effect on psychological responses may be due to the athletes’ self-awareness of their physical deficits at 6 months after ACLR.Level of evidenceLevel II, randomised controlled trial.

Background and Purpose The purpose of this study was to determine the effect of a 6-month neuromuscular training (NT) program versus a traditional strength training (ST) program following anterior cruciate ligament (ACL) reconstruction. Subjects Seventy-four subjects with ACL reconstruction participated in the study. Methods The study was a randomized, single-blinded, controlled trial. The NT and ST groups were tested preoperatively and at 3 and 6 months. The main outcome measure was the Cincinnati Knee Score. Secondary outcome measures were visual analog scales (VASs) for pain and function, the 36-Item Short-Form Health Survey (SF-36), hop tests, isokinetic muscle strength, proprioception, and static and dynamic balance tests. Results The NT group demonstrated significantly improved Cincinnati Knee Scores and VAS scores for global knee function compared with the ST group at the 6-month follow-up. There were no significant differences between the groups for the other outcome measures (ie, hop, balance, proprioception, and muscle strength tests). Discussion and Conclusion The results of this study suggest that exercises included in the NT program should be part of the rehabilitation program following ACL reconstruction.
