(English) episode 212-Fixing Quad Muscle Shutdown After ACL Surgery

This scoping review examines the effectiveness of various medical interventions for arthrogenic muscle inhibition (AMI), a common neurological barrier to quadriceps recovery following ACL reconstruction. The authors analyzed twenty studies to determine which therapies best address quadriceps activation failure and related muscle weakness. Their findings provide moderate-quality evidence supporting the use of cryotherapy and physical exercise, including both resistance training and hamstring fatigue protocols, as primary treatments. In contrast, researchers found only low-quality evidence for the efficacy of electrical stimulation (NMES and TENS) and vibration therapy. Other common methods, such as taping, bracing, and superficial heat, showed no clinical benefit in restoring muscle function. The review concludes that ice and structured movement are currently the most reliable tools for overcoming the neural pathways that inhibit muscle strength after knee surgery.(Sonnery-Cottet B, Saithna A, Quelard B, Daggett M, Borade A, Ouanezar H, et al.
