Stability 2: ACL Reconstruction +/- Lateral Tenodesis with Patellar vs Quad Tendon (Protocol # PRO19020231)


The purpose of this multicenter study is to compare outcomes between patients who will undergo different types of ACL reconstruction. All patients will have a tendon from their own knee used to reconstruct the ACL. Prior to knee surgery, researchers will randomize (i.e. a coin toss) to determine if ACL reconstruction will be done with patellar or quadriceps tendon and if the lateral extra-articular tenodesis will or will not be added to the ACL surgery. We will follow-up with participants as they undergo treatment and recovery after surgery for 2 years.
