I ruptured my Anterior Cruciate ligament 5 years ago. I can't seem to regain strength endurance in that leg. I ran my first half marathon for some time this weekend and found all sorts of issues with my biomechanics leading to anterior ankle pain Thor the first 4 miles and hip pain for the last 4 miles all on the alledly good leg. I think I am overcompensating. Any suggestions to build up the leg above and beyond one legged a squats, lunges, leg curls and squats on a balance board?
