Pins don't usually move. I had two in my wrist years ago. The bone grows around them pretty quickly. I don't remember what your surgery date was, but is he moving around too much? Don't let him overdo it yet, especially if he's dragging the leg. Healing takes time, and he's better off keeping it immobile. Some swelling will be there and it'll be abnormal looking.
Also, remember that you don't really notice his knee anatomy when he has hair. It's going to make you uneasy for a while. Has he had a checkup recently? |
