ARTHROGENIC INHIBITION IN THE POSTOPERATIVE PERIOD OF ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION: A LITERATURE REVIEW

Abstract

Anterior cruciate ligament (ACL) reconstruction is a common procedure, especially in active individuals. However, quadriceps arthrogenic muscle inhibition (AMI) represents a significant challenge in postoperative rehabilitation, compromising muscle activation and functional return. This bibliographic review aims to analyze the main findings of recent literature on AMI after ACL reconstruction, addressing its causal mechanisms, functional impact, and therapeutic strategies. Scientific articles published between 2020 and 2026, in Portuguese and English, were consulted in the PubMed and Scielo databases. The results indicate that AMI persists for months after surgery, affecting neuromuscular activation. Interventions such as neuromuscular electrical stimulation (NMES), cryotherapy, and biofeedback have shown effectiveness in its reduction. It is concluded that a deep understanding of AMI and the application of evidence-based therapeutic approaches are crucial to optimize rehabilitation and safe return to activities.
