Effects of Anterior Cruciate Ligament Reconstruction Timing on Post-Operative Motor Performance and Proprioception
Objective To evaluate the effects of anterior cruciate ligament(ACL)reconstruction tim-ing on the motor performance and proprioception by clinical evaluation as well as proprioception and motor per-formance tests on the patients more than 2 years after ACL reconstruction.Methods The patients who underwent ACL reconstruction in the National Institute of Sports Medicine,General Administration of Sport of China from January 2015 to January 2021 and met the inclusion criteria were followed up,and the postoperative data were collected retrospectively.Fifty-six patients who met the inclusion criteria were included in this study and categorized into two groups:early surgery(n=28,who underwent ACL reconstruction ≤3 weeks after injury)and delayed surgery(n=28,who underwent ACL reconstruction＞3 weeks after injury).The basic information,clinical evaluation results,proprioception,and motor performance were compared between the two groups.Results The ACL return to sport after injury scale(ACL-RSI)score in the early surgery group was higher than that in the de-layed surgery group[(68.68±22.04)scores vs.(55.82±24.87)scores,P=0.045].There was no difference in the range of motion of the knee joint,the positive rate of pivot shift test,or the scores of Tegner,Marx,Ly-sholm,knee injury and osteoarthritis outcome score(KOOS),and international knee documentation committee(IKDC)between the two groups(all P＞0.05).Although there was no significant difference in range of motion of the knee joint between the two groups,the proportion of knee flexion and extension affected in the early surger-y group was smaller than that in the delayed surgery group.Neither motor performance(isokinetic strength test,Y-balance test,and single-leg jump test)nor proprioception had difference between the two groups(all P＞0.05).Conclusions Early ACL reconstruction outperformed delayed ACL reconstruction in improving the psy-chological health,emotions,and confidence in returning to sport,accelerating functional recovery of the pa-tients.The timing of ACL reconstruction has no significant effect on the short-term postoperative knee stability,knee function,motor performance,or proprioceptive recovery of the patients.Early ACL reconstruction is recom-mended for improving the clinical outcomes.
