To explore the technique of diagnosis and treatment of intra-articular giant cell tumor of tendon sheath (GCTTS) in knee joint, and to evaluate its clinical results.
Twelve patients with GCTTS treated during 15 years were reviewed. Nine cases were misdiagnosed with meniscus injury (6 cases) and chronic synovitis (3 cases) before operation, only 3 cases were confirmed the diagnosis of GCTTS by MRI. Complete tumorectomy under arthroscope was performed on all 12 cases.
The results of clinical and radiographic followed-up of 9 patients for 1 to 10 years after operation was satisfactory. Clinical symptoms disappeared, range of motion and X-ray findings were normal. There was no recurrent case found.
Arthroscopic removal of GCTTS is an effective treatment. Tumor wide resection and debriding the channel which tumor passed through are the key point to prevent the recurrence after operation.
探讨膝关节腱鞘巨细胞瘤（GCTTS）的诊断与治疗技术，并评估其临床效果。
回顾性分析15年间收治的12例GCTTS患者。术前9例误诊为半月板损伤（6例）和慢性滑膜炎（3例），仅3例经MRI确诊为GCTTS。12例均在关节镜下行肿瘤全切除术。
9例患者术后1至10年的临床及影像学随访结果满意。临床症状消失，活动范围及X线表现正常。未发现复发病例。
关节镜下切除GCTTS是一种有效的治疗方法。肿瘤广泛切除并清理肿瘤通过的通道是预防术后复发的关键。
