Discoid lateral menisci were common morphological anomaly and several classifications were proposed. Watanabe et al classified all discoid menisci, as seen arthroscopically, into three types 1) complete 2) incomplete and 3) Wrisberg ligament type. The purpose of this study is to report a rare case of both painful snapping knee joints in 6 year-old female. On arthroscopic examination, complete lateral discoid meniscus which consisted of taut Wrisberg ligament and intact tibial insertion of posterior horn was found, and abnormal anterior cruciate ligament(ACL) which has expanded femoral origin over the posterior articular surface of lateral femoral condyle was also found. At the time of arthroscopic surgery, hypertrophied high-riding Wrisberg ligament was resected, and expanded femoral origin of the anterior cruciate ligament was partially resected nearly to normal margin, and discoid lateral meniscus was saucerized. After these procedures, abnormal snapping sound was disappeared in full range of motion. On the follow-up examination after 1 year, pain and snapping sound were disappeared and any instability and limping were not found.

Discoid lateral meniscus is a well-known entity of the knee whereas Wrisberg ligament-type discoid lateral meniscus is extremely rare. This is a report of a case of bilateral discoid lateral meniscus with peripheral detachment.
