Quadriceps Morphology 6- to 60-Months After Anterior Cruciate Ligament Tear.

ABSTRACT: The purpose of this study was to compare quadriceps morphology between legs and individuals with a first-time anterior cruciate ligament (ACL) tear and uninjured controls. This was an exploratory cross-sectional study. We enrolled participants who were aged 19-35 years, and 6-60 months after a first-time ACL tear as well as uninjured controls. Participants attended two sessions separated by a minimum of 7 days. Bilateral knee extensor concentric and eccentric strength and rate of torque development (RTD) were assessed at the first session, and bilateral vastus lateralis muscle biopsies were obtained at the second. Muscle fiber-type specific cross-sectional area (fCSA), fiber-type proportions, and extracellular matrix area were calculated. Between-limb and between-group differences were est
