Re: Ankle Arthroscopy
Okay, so they diagnosed a ligament tear. If this tear hasn't healed on its own by this time, it probably should be repaired surgically. The surgeon could do this at the same time as the arthroscopy, whether he will I don't know.
If the surgeon just goes in, looks around and maybe removes scar tissue, you'll be on crutches just for a few days, and mostly recovered within a few weeks. I had exactly that procedure in March 2008, and I had a marvelous outcome. I did have to stay home and ice and elevate for a couple days, though, as it was very swollen at first.
However, if he does the ankle ligament repair, that can't be done arthroscopically, so he'll have to make a bigger incision. Also, you'll be on crutches in a boot or cast for several weeks, because the sewn-up ligament needs to heal and harden before you can walk.
About that pain behind the ankle: It could be peroneal tendonitis, or it could just be spasms in the peroneal muscles. I had a lot of trouble with that during my ankle war, because limping put abnormal strain on those muscles. Even though the problem came from the muscles, I felt it down in the ankle. Try massaging the outer side of the calf, along the fibula. See if that loosens it up any.
If not, do let the surgeon know before you go under. The peroneal tendon is in back of the ankle, and the traditional arthroscopy portals are in the front. It's tough to see that area from where they put the camera.
