Inverted cyclops lesion after anterior cruciate ligament reconstruction.

We report the case of an inverted cyclops lesion limiting extension of the knee joint after a four-strand hamstring anterior cruciate ligament (ACL) reconstruction. One case has been reported previously following a bone-tendon-bone reconstruction of the ACL but a similar case has not been reported.
