title: A case report: locking because of cyclops syndrome occurring after partial rupture of the anterior cruciate ligament.
abstract: There have been a few reports of cyclops syndrome following a partial rupture of the anterior cruciate ligament (ACL) without surgical reconstruction. We have reported for the first time a case of cyclops lesion with locking symptoms after partial rupture of the ACL. A 14-year-old girl twisted her right knee when landing after a jump while playing basketball, and locking symptoms of the knee appeared. Cyclops syndrome occurred because of a partial rupture of the posterolateral bundle of the ACL was diagnosed and removed as a lump by punch. After resection of the lesion, the locking symptom was no longer observed.
