Replying to I Knee'd some answers...

Some background info... Last season I put a tear in my MCL. I went to physio, got some exercises to do (which i was sloppy about) and started skiing again; overall it seemed like a pretty minor inconvenience. But this past summer I went to physio again and they said that there was scar tissues built up and my good leg has been compensating. But that's not really whats been worrying me, it's the HOLE IN MY KNEECAP?! It's probably about a cm wide and two cm's long, and its on my "bad knee". Has anyone ever had this same phenomenon happen to them? I know there's lots of ppl on here who have had knee injuries and perhaps have asked their doctors about similar things??
