Description
Pigmented villonodular synovitis (PVNS) is one of the rare conditions, which typically involves the knee joint. There are two main types of PVNS-localized and diVuse, with localized type relatively rare when compared to diVuse PVNS. This case report describes a 30-year-old man presenting with a short history of swelling, posterolateral joint line pain and intra-articular mechanical locking of the left knee. There was localized tenderness, and McMurray’s test was positive. Arthroscopy revealed a Wrm pedicular localized pigmented villonodular synovitis originating from the beneath of the body and posterior horn of the lateral meniscus. The lesion was excised arthroscopically. This allowed a return to normal daily activities. Localized pigmented villonodular synovitis (LPVNS) arising from posterolateral aspect of knee mimicking lateral meniscal tear has not been reported in the literature. Though rare, LPVNS should be kept as diVerential diagnosis of meniscal tear. LPVNS can be managed eVectively with arthroscopy.
