Effects of Anterior Cruciate Ligament Reconstruction Timing on Post-Operative Motor Performance and Proprioception

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Rehabilitation Science

Background:

• Anterior cruciate ligament (ACL) injuries are common in athletes, often requiring surgical reconstruction.
• The optimal timing for ACL reconstruction remains a subject of debate, influencing patient outcomes.
• Understanding the impact of surgical timing on functional recovery and performance is crucial for clinical decision-making.

Purpose of the Study:

• To evaluate the long-term effects of early versus delayed ACL reconstruction on motor performance and proprioception.
• To compare clinical outcomes, including knee stability and functional scores, between patients undergoing early and delayed ACL reconstruction.
• To determine if surgical timing influences psychological readiness for returning to sport.

Main Methods:

• Retrospective follow-up study of 56 patients who underwent ACL reconstruction.
• Patients were categorized into early surgery (≤3 weeks post-injury) and delayed surgery (>3 weeks post-injury) groups.
• Evaluations included clinical assessments, proprioception tests, motor performance tests, and patient-reported outcome scales (e.g., ACL-RSI, KOOS, IKDC).

Main Results:

• The early surgery group demonstrated significantly higher ACL-RSI scores, indicating better psychological readiness for return to sport.
• No significant differences were observed between groups in knee range of motion, pivot shift test results, or functional scores (Tegner, Marx, Lysholm, KOOS, IKDC).
• Motor performance and proprioception showed no significant differences between early and delayed ACL reconstruction groups.

Conclusions:

• Early ACL reconstruction is associated with improved psychological outcomes and confidence in returning to sport.
• Surgical timing does not significantly affect short-term postoperative knee stability, function, motor performance, or proprioceptive recovery.
• Early ACL reconstruction is recommended to enhance overall clinical outcomes and patient confidence.
