Abstract

Restriction of extension of the knee joint is one of the most common complications after anterior cruciate ligament (ACL) reconstruction surgery. Impingement caused by a fibrous tissue mass related to the graft (named as cyclops lesion) has been found to be an important cause of blocking complete extension.
We present our experience of managing two cases of cyclops lesions who reported with pain and loss of knee extension after arthroscopic ACL reconstruction.
The clinical and radiological findings were suggestive of a cyclops lesion which were later confirmed during arthroscopic procedure. After a trial of physiotherapy, these patients were treated arthroscopically with shaving, radiofrequency ablation and removal of obstructing nodules which were present near the tibial insertion of ACL graft. Post-operatively, pain subsided and full range of motion was restored.
