Participants in the ACL reconstructed group should have had an ACL reconstruction in the last 4-24 months using a semitendinosus gracilis graft.
Participants in the osteoarthritis group will have radiologically diagnosed osteoarthritis of the knee with a kellgren lawrence score of greater than or equal to 2.
Control subjects who volunteer but have a history of injury or pathology in either knee joint may be excluded
Participants from all groups may be excluded if they have a history of spinal surgery, low back pain in the last 6 months with associated neurological signs and symptoms or any systemic disease that prevents them from participating in maximum strength testing.
