That : That blanket statement may not be true at face value. The falls may be have an underlying mechanical problem or be a poor training problem. Look into your technique and video your moves. Please indicate your sex, age and if you have knock or valgus knees. You may be able to avoid additional injuries with timely changes.

Possible: You need to see ortho doc for an eval. Not sure what injuries you already sustained.
