Pigmented villonodular synovitis (PVNS) is a relatively rare condition. It occurs in two forms: a diffuse form involves the entire synovium and occurs in the majority of cases, and a localized form involves a discrete section of the synovium. The disorder almost always involves a single joint and the knee is most commonly affected. We report on three cases of localized PVNS that involved the patellar fat pad and synovium. Diagnostic and therapeutic arthroscopies were performed, and typical localized PVNS was found. Complete resection of the lesions was performed arthroscopically. Arthroscopy can be used as an effective diagnostic and therapeutic tool for identification and treatment of intra-articular localized PVNS of the knee.
色素沉着绒毛结节性滑膜炎（PVNS）是一种相对罕见的病症。它有两种形式：弥漫性形式累及整个滑膜，在大多数病例中出现，而局限性形式累及滑膜的一个离散部分。该病症几乎总是累及单个关节，膝关节最常受累。我们报告了3例累及髌下脂肪垫和滑膜的局限性PVNS病例。进行了诊断性和治疗性关节镜检查，发现了典型的局限性PVNS。通过关节镜对病变进行了完整切除。关节镜可作为识别和治疗膝关节关节内局限性PVNS的有效诊断和治疗工具。
