I'm 50. I have been playing a lot on a hard court, probably too much and I play basketball a couple of times a week. Last week my left knee felt weak, no pain, just kind of wonky. When riding my scooter for an hour to work it was uncomfortable unless I straightened it, I couldn't keep in bent. I rested because we had a tournament on Sunday. Sunday morning I played singles early and felt great. At the tournament I jumped once and then a second time for an overhead and when I came down there was a pronounced click-click and I had to stop, but then played on, but couldn't move. The next day I couldn't walk. After another day of rest and getting some crutches it feels better and I can walk around now less than 48 hours since the injury. My question is what happened and is it possible I will be able to play again soon? Thanks in advance.
