OBJECTIVE: To investigate the effect of progressive resistance exercise compared with low intensity home-based exercises on knee-muscle strength and joint function in people with anterior cruciate ligament (ACL) reconstruction and persistent hamstring strength deficits at 12–24 months after surgery.

CONCLUSION: In people with persistent hamstrings muscle strength deficits after ACL reconstruction, 12 weeks of supervised progressive strength training was superior to low intensity home based exercises for improving maximal knee flexor muscle strength and some patient reported outcomes.
