Mobility, Range of Motion, then strength are the keys to healthy knees... hip mobility, hamstring strength, and proper alignment can all be achieved with an appropriate approach to strength and conditioning.
I've torn my left ACL (high school basketball) and broken my left femur (skiing accident 2010) and suffer absolutely 0 negative effects from either injury. That said, I hammer my legs at the gym with square stance for strength/power, split stance for mobility, single leg for symmetry and balance, and plyometric activities on a weekly basis. I don't believe in tights, orthotics, or other exterior contraptions used to make up for physical compensations.
