Changes in stair ascent biomechanics two to eight years after ACL reconstruction are associated with patient-reported outcomes

摘要

Background: Anterior cruciate ligament (ACL) injury is often followed by quadriceps deficits that are apparent with gait analysis. The deficit frequently remains after ACL reconstruction (ACLR). As such, evaluation of ACLR patients could be enhanced by a simple method to detect quadriceps deficits. Analyzing forward trunk flexion during stair ascent has been suggested as an assessment of quadriceps function that can be visualized with relatively simple instrumentation.
