Tracking Muscle Quality Following ACLR

The ACL (anterior cruciate ligament) is a ligament in the knee that helps control how the knee moves. When someone tears their ACL, the muscles around their knee get weaker because they can’t fully use and exercise the knee. ACL reconstruction surgery repairs the torn ligament, but the muscles are still weak from not being used normally. After surgery, physical therapy helps strengthen the muscles again through exercises that safely move the knee joint. This research is being done to compare methods of examining skeletal muscle quality during rehabilitation following ACL reconstruction. This study will help researchers and clinicians better understand the changes that occur in muscles following ACL reconstruction, and what methods are useful for tracking progress.

  • Ages 15-40
  • Individuals who have undergone ACL reconstruction surgery in the past two weeks.
  • Willingness to participate in physical therapy (including coverage of financial costs) and scheduled laboratory visits after reconstruction surgery.
