I have had two ACL reconstructions on the same knee, using my patellar tendon and quadriceps tendon as grafts. I am now almost two years post-op, but I’m experiencing an issue where my kneecap feels like it's shifting out of place, especially during pivoting movements. When this happens, I usually have to extend my leg fully until I hear a 'click,' after which the joint feels normal again. I find it weird because it doesn’t hurt, and there’s never any swelling. (Just a tiny bruise on the knee cap) Could this be patellar instability caused by using both the patellar and quadriceps tendons as grafts? I’m wondering if the harvesting of those tissues has made the kneecap less stable or 'anchored' than it should be.
