I really don't want to make you all feel bad but I've been at it for 18 years. I get it fixed and it stretches back out. So far I've had at least one of each of the following: PCL, MCL, LCL, HTO, Femoral Ost., TKR, Posterior Capsule and Quad Tendon. They used the cadaver with my quad tendon hoping it wouldn't stretch out and ended up taking it out and tried using my hamstring. I now have a 55º lag on a SLR and will fall if my leg isn't completely straight when I put weight on it. (I use a full length leg brace and crutch to walk.) I'm having the whole extensor mechanism replaced in 3 weeks. The OS is going to use a cadaver patella, patellar tendon and quad tendon in place of my own. I didn't know this forum was here and while I don't wish this problem on anyone, it's nice to know there are others out there who understand and have been through it. Good Luck!
