BLOCKED KNEE EXTENSION DUE TO A CYCLOPS LESION IN A TOTALLY TORN ACL WITH NO PRIOR RECONSTRUCTION. CASE REPORT
Keywords:
CYCLOPS LESION, KNEE ARTHROSCOPY, TORN ACL, BLOCKED EXTENSIONAbstract
The cyclops lesion, also known as localized anterior arthrofibrosis is a widely recognized complication of anterior cruciate ligament (ACL) reconstruction that may lead to a mechanical block. In this report, we describe a rare case, where the patient was suffering from progressive loss of knee extension without having any prior surgery. An arthroscopy revealed a completely torn ACL along with the presence of a cyclops lesion. Subsequently, the patient was treated by resection of the cyclops lesion and ACL reconstruction using hamstring-tendon graft which enabled the patient to regain stability and full joint range of motion.
