I am almost 3 months out from knee replacement. I wanted to ask a question that is not terribly crucial but is of interest to me. I have noticed (and so has my wife) that the hair growing on my knee after being shaved before surgery, is much thicker and darker than it was before the surgery and also thicker than on my other knee. It is as if someone had put Rogain on steroids on my knee. Has this happened to anyone else? If so, will the hair return to normal at some point?
