Graft impingement is when a graft, such as a cruciate ligament reconstruction graft, interferes with the smooth functioning of the joint by scraping along the sharp edge of bone or by bunching up into a lump.


Cyclops lesion

The most well known impingement after cruciate ligament reconstruction is the cyclops lesion, where the ligament tissue bunches up in the notch between the two rounded ends of the femur.
