Does the giving way cause pain after the acute episode?
Yes. It also can cause more damage to the articular surface and the meniscus. (leading to late osteoarthritis) Does the harvest of the graft cause a problem with the knee later on? Yes. There is some weakness of the hamstrings after removal of the semi-tendinosus and the gracilus tendons. There is usually no weakness after patellar tendon harvest, but pain around the knee cap is common post-operatively.
