Abstract

BACKGROUND: Preoperative quadriceps and hamstring muscle weakness may predispose patients to strength deficits and prolonged recovery in the setting of anterior cruciate ligament (ACL) injury. Three-dimensional (3D) magnetic resonance imaging (MRI) analysis has been developed to provide a comprehensive assessment of the thigh musculature. PURPOSE: To (1) describe the magnitude of quadriceps and h…
