I feel ya on this one when I was playing foot ball in H.S. I had my knee scoped and they removed about 90 percent of the cartilige on my left knee
sewed me back up and said that I was good to go.
2 weeks later they said I was ok to practice . I lasted 20 minutes and dislocated my knee be cause it was not strong enough broke my knee cap in half when it dislocated.was in a straight leg brace for 8 weeks was on crutches for four of those 8 weeks, end of football career, that summer sucked.
