Abstract
- Localized pigmented villonodular synovitis (LPVNS) is a rare lesion that can affect any joint, although it is most frequently found in the knee. When LPVNS affects the knee, it is usually a single mass of pedunculated appearance. We present a LPVNS occurred from the junction of the anterior horn of the lateral meniscus and the joint capsule in the knee. It detached and then moved at an unusual location, which caused pain, limitation of knee flexion and locking.
