Re: stretched ligaments in ankle
Yes, the recovery period is long. Trying to shorten it will probably result in the surgery coming undone. However, most people who've had it are much better afterwards. The surgeon could clean up any bone chips or scar tissue that are causing you pain or restricted motion, and he could tighten the ligaments so your ankle is stable. You might always have to be a tiny bit careful of the ankle, but it should be close to normal. If the ligaments stay loose, repeated sprains could cause more damage.
Talk to an orthopedic surgeon who does these types of procedures regularly. Ask him if you are a good candidate, and what the probable outcome would be. Also ask him what will happen if you don't have the surgery.
How much trouble are you having with the ankle right now? If you are rolling it frequently, or having regular significant pain, it's probably worth it.
