Synovial chondromatosis is a rare, benign condition of unknown etiology in which the synovium undergoes metaplasia leading to cartilaginous nodules that ultimately break free, mineralize, and even ossify. The most commonly involved joint is the knee. Patients may be asymptomatic or may present with pain, swelling, and limited range of motion. Plain radiographs can be diagnostic and mineralized nodules are pathognomonic. Recommended treatment involves arthroscopic or open removal of loose bodies with or without a synovectomy to prevent further articular and periarticular destruction and to relieve symptoms.
滑膜软骨瘤病是一种病因不明的罕见良性疾病，其中滑膜发生化生，导致软骨结节最终脱落、矿化甚至骨化。最常受累的关节是膝关节。患者可能无症状，也可能表现为疼痛、肿胀和活动范围受限。X线平片可用于诊断，矿化结节具有特征性。推荐的治疗方法包括通过关节镜或开放手术切除游离体，可同时或不同时进行滑膜切除术，以防止进一步的关节和关节周围破坏并缓解症状。
