Ten years ago I had MCL, ACL, and PCL reconstruction. I was required to wear a brace for a long time and afterwards I noticed there was a huge dent in my thigh and a small lump. I am overweight and have extremely fatty thighs and it seemed like it only affected that fatty part of my leg. The muscle seemed ok. They told me they took out some of my muscle from my thigh to reconstruct my ligaments so I just thought it was fat damage because of that. Recently though, it's starting to bother me a little bit. It's not intense, it's kind of a dull pain every now and then. Should I be concerned?
