Abstract:
Locking of the knee is commonly reported in patients presenting to an orthopedic surgeon. This case report describes a rare cause of knee locking: subluxation of the lateral meniscus without an associated tear. This case highlights the importance of the popliteus recess in stability of the lateral meniscus. Injury to this area may lead to meniscal subluxation and knee locking.
