To discuss short-term effect of rotating hinge knee prosthesis.
From July 2002 to April 2005, 17 cases of severe knee joint deformity and instability received rotating hinge knee prosthesis for total knee arthroplasty. There were 8 males and 9 females, aging from 4l to 79 years. The left joints were involved in 10 cases and right joint in 7 cases. All patients were admitted because of pain. The course of disease was from 1 to 7 years. There were 10 cases of osteoarthritis, 5 cases of rheumatoid arthritis, 1 case of traumatic arthritis after operation of left femur fracture,and 1 case of traumatic arthritis with injury of anterior cruciate ligament, meniscus medialis and medial collateral ligament after operation of left fracture of tibial plateau. According to HSS (hospital for special surgery) scoring system, the preoperative score was 36 to 58 with an average of 48.6. The preoperative flexed motion range of articulation was 21 degrees to 80 degrees with an average of 57.4 degrees.
All patients were followed up from 7 months to 3 years with an average of 23. 6 months. There were no complications of thrombogenesis of veins of lower extremity, pulmonary embolism, palsy of peroneal nerve, fracture, and breakage of extended knee structure. Infection occurred in 1 case at 3 months postoperatively, the prosthesis was dislodged, antibiotic-impregnated cement was filled with knee joint, two-stage arthroplasty was expected. At the last follow-up, the HSS score was 78 to 98 with an average of 91.1 in 16 patients. The flexed motion range of articulation was 75 degrees to 100 degrees with an average of 85.2 degrees at 2 weeks postoperatively. The flexed motion range of articular was 85 degrees to 123 degrees with an average of 108.3 degrees at the last follow-up. There were significant differences in HSS score and motion range of articular between preoperation and the last follow-up (P < 0.05).
The short-term outcome of rotating hinge knee prosthesis is good and a long term follow-up is necessary.
探讨旋转铰链膝关节假体的短期疗效。
2002年7月至2005年4月，17例膝关节严重畸形和不稳定患者接受旋转铰链膝关节假体全膝关节置换术。其中男性8例，女性9例，年龄41～79岁。左膝10例，右膝7例。所有患者均因疼痛入院。病程1～7年。骨关节炎10例，类风湿关节炎5例，左股骨骨折术后创伤性关节炎1例，左胫骨平台骨折术后创伤性关节炎伴前交叉韧带、内侧半月板及内侧副韧带损伤1例。根据美国特种外科医院（HSS）评分系统，术前评分为36～58分，平均48.6分。术前关节屈曲活动范围为21°～80°，平均57.4°。
所有患者随访7个月至3年，平均23.6个月。未发生下肢静脉血栓形成、肺栓塞、腓总神经麻痹、骨折及膝关节伸展结构断裂等并发症。术后3个月1例发生感染，假体松动，膝关节腔内填充抗生素骨水泥，拟二期置换。末次随访时，16例患者HSS评分为78～98分，平均91.1分。术后2周关节屈曲活动范围为75°～100°，平均85.2°。末次随访时关节屈曲活动范围为85°～123°，平均108.3°。术前与末次随访时HSS评分及关节活动范围差异有统计学意义（P<0.05）。
旋转铰链膝关节假体的短期疗效良好，仍需长期随访。
