Abstract：
Synovial osteochondromatosis (SOC) is a rare, benign condition of unknown etiology characterized by the formation of cartilaginous loose bodies. This often leads to early osteoarthritis with decreased range of motion and pain. Clinical presentation most often is reported as monoarticular pain affecting the knee or less commonly the hip shoulder or elbow. Diagnosis can be confirmed on x-ray imaging where the characteristic synovial bodies will be identified. Management with early debridement of the synovium will often be curative but more complex cases may require further surgical management. We present a 33-year-old male presented with localized left knee pain. Given the history of new-onset pain, left knee x-rays were obtained that revealed a displaced patella with multiple ossific densities around the left knee which were suspicious for a new diagnosis of SOC. Due to its nonspecific symptoms and imaging, the diagnosis of SOC is often delayed or missed. Therefore, prompt diagnosis and treatment are important in order to avoid irreversible cartilage destruction in the joint, prevent the development of chronic pain, and reduce the risk of malignant transformation.
摘要：
滑膜骨软骨瘤病（SOC）是一种罕见的，病因不明的良性疾病，其特征是软骨松散体的形成。这通常导致早期骨关节炎,具有减小的运动范围和疼痛。据报道，临床表现最常见的是影响膝盖或不太常见的髋肩或肘部的单关节疼痛。可以在X射线成像上确认诊断，其中将识别特征性的滑膜体。早期清除滑膜的治疗通常是治愈性的，但更复杂的病例可能需要进一步的手术治疗。我们介绍了一名33岁的男性，表现为局部左膝疼痛。鉴于新发疼痛的病史，获得左膝关节X线，显示左膝关节周围有多个骨化密度的移位髌骨，这对于SOC的新诊断是可疑的。由于其非特异性症状和影像学，SOC的诊断经常延迟或错过。因此,及时的诊断和治疗对于避免关节中不可逆的软骨破坏非常重要，预防慢性疼痛的发展，并降低恶性转化的风险。
