My second one is different. It's taking longer. They were both very similar pre-op. Both needed a lot of straightening and re-alignment. This one at six months is giving tenderness and sometimes sharper pain on the lateral part of my knee where the lateral co-lateral ligament (I believe) is. It feels like it catches on something and locks. Then it takes up to a day to be able to straighten it and relieve the pain. Surgeon said it might be catching on some soft tissue and should go away and physio has worked on it with no effect. If anyone ever had a torn cartilage lock they would know the feeling. Just wondered if anyone else had this? So many different problems on here!
