目的报道膝关节滑膜软骨瘤病１５例，均用关节镜诊断及治疗，所有病例均经病理检查证实。作者对关节镜在本病诊断中的优点、分型及治疗方法进行探讨。方法所有１５例病例均为膝关节病变，左膝关节６例，右膝关节７例，双侧膝关节２例。主要临床症状为关节疼痛、交锁及反复肿胀。关节镜术野好，可全面检查关节腔，具有放大作用，可提高本病的诊断率并有助于分型，关节镜下可将本病分为三型：表浅型、深在型和游离体型。治疗采用关节镜下游离体取出术、局限性滑膜切除术和并发退行性关节病变者行关节清理术。结果随访１２例，平均３２年，所有病例术后功能良好，未见复发。结论关节镜有助于本病的诊断与治疗，关节镜下取出游离体及切除异常滑膜组织是治疗本病的良好手段。
Objective To report 15 cases of knee synovial chondromatosis, which were diagnosed and treated with arthroscopy. All cases were confirmed by pathological examination. The author discusses the advantages, types and treatment of arthroscopy in the diagnosis of this disease. Methods All 15 cases had knee joint disease, 6 left knee joints, 7 right knee joints and 2 bilateral knee joints. The main clinical symptoms are joint pain, interlocking and repeated swelling. Arthroscopic surgery is good, can fully check the joint cavity, has a magnifying effect, can improve the diagnosis rate of this disease and contribute to classification, arthroscopy can be divided into three types of this disease: superficial, deep in type and Free body type. Treatments were performed with arthroscopic dissection, local synovectomy, and joint debridement for patients with degenerative joint disease. Results Twelve patients were followed up for an average of 3. 2 years. All the patients had good postoperative function and no recurrence. Conclusion Arthroscopy is helpful for the diagnosis and treatment of this disease. Arthroscopic removal of free bodies and removal of abnormal synovial tissue are good means for the treatment of this disease.
