目的评价旋转铰链型人工膝关节置换治疗膝关节周围骨巨细胞瘤的疗效。方法自2001年1月至2008年1月收治膝关节周围骨巨细胞瘤31例,男性13例,女性18例,年龄19～56岁,平均33.5岁。股骨远端20例,胫骨近端11例。Companacci分级,Ⅱ级7例,Ⅲ级24例。肿瘤已穿破骨皮质或侵犯至关节软骨下者2例,已发生病理性骨折者3例,瘤组织病理检测具有较强的侵袭性者5例,已有一次或多次复发者21例。所有患者行瘤段切除、旋转铰链型人工膝关节置治疗。结果随访12～96个月,所有患者无局部复发或远处转移。患者MSTS评分为17.0～27.0(24.0±2.5)分,肢体功能优23例,良6例,中2例,优良率为93.5%。结论旋转铰链型人工膝关节置换是治疗膝关节周围骨巨细胞瘤的有效方法 ,能减少局部复发及提高临床效果。
Objective To evaluate the therapeutic effect of rotary-hinge type artificial knee joint replacement on giant cell tumor of the knee. Methods From January 2001 to January 2008, 31 cases of giant cell tumor of the knee were treated around the knee. There were 13 males and 18 females, aged from 19 to 56 years (average 33.5 years). 20 cases of distal femur and 11 cases of proximal tibia. Companacci grade, grade Ⅱ 7 cases, Ⅲ grade 24 cases. The tumor had penetrated the cortical bone or infiltrated into the articular cartilage in 2 cases, pathological fracture occurred in 3 cases, tumor histopathology in patients with strong invasive in 5 cases, one or more recurrence in 21 cases. All patients with tumor resection, rotation hinge type artificial knee joint therapy. The results were followed up for 12 to 96 months, all patients without local recurrence or distant metastasis. The MSTS score was 17.0-27.0 (24.0 ± 2.5) points, excellent in 23 cases of limb function, good in 6 cases and fair in 2 cases. The excellent and good rate was 93.5%. Conclusion Rotating hinge artificial knee joint replacement is an effective method for the treatment of giant cell tumor of the knee. It can reduce the local recurrence and improve the clinical effect.
