Quadriceps Srength and Neuromuscular Strategies Continue to Improve Two Years after Acl Reconstruction

After anterior cruciate ligament (ACL) rupture, some individuals demonstrate the ability to dynamically stabilize their injured knee (potential copers). The majority of ACL deficient individuals, however, are classified as non-copers; they have knee instability with daily activities, exhibit quadriceps weakness, and have altered movement patterns. Prior to surgery, non-copers have been shown to make initial contact with less knee flexion on their involved side, achieve less peak knee flexion, and exhibit reduced knee power absorption during weight acceptance [1]. These non-copers customarily undergo ACL reconstructive surgery (ACLR) to repair the damaged ligament.
