Do knee caps really help to prevent knee/ LCL injuries? I do a lot of boot camp style/ PX90 workouts, my knees gets a good amount of impact when I do a lot of cardio during my workouts. Is it advisable to have knee braces/ supporters, do they help reduce the stress or is yet another medical myth?

Please advice

Is there a medical professional advising you to wear some sort of supportive device? The advice is not to go use a brace if you're healthy. –  Dave Liepmann May 28 '14 at 14:09
