My injury was quite different than many of you who have commented, but nerve damage was a huge part of it. I completely dislocated my knee blowing out all my ligaments, Iliotibial Band, and hamstring....basically leaving my tibia on top of my femur about 8 inches higher than its original location. Well, that obviously caused nerve damage in my leg to a point where I was unable to move any part of my leg for nearly 3 months, but most of it did come back. I still have little to no activity in my Vastus Medialis Obligue, so the leg looks goofy as shit. Nerves regenerate something like 3-5mm per/day depending on the size, so it takes some time. My damage was in the femural nerve, so I had to relearn how to use my leg. Someone mentioned l-carnitine...thats what my PT's put me on along with basic leg exercises, and a tens unit. Basically, there are no special excersises that will help the nerve regenerate faster, so my advice is to work your ass off retraining the muscle and be patient. Oh, one thing I did was use my tens unit while I was doing my leg excersises, which seemed to help me increase the weight and ultimately build that muscle back up. The tens unit will also help a little bit with the pain. Hope this helps!
