摘要
目的探讨旋转铰链型人工膝关节临床应用的近期疗效。方法2002年7月～2005年4月，应用旋转铰链型人工膝关节假体进行全膝关节置换术治疗膝关节严重畸形和不稳定17例17膝。其中男8例，女9例；年龄41～79岁，平均59岁。左侧10例，右侧7例。患者均因膝关节疼痛人院，病程1～7年。其中骨性关节炎10例，类风湿性关节炎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合并前交叉韧带、内侧半月板损伤及内侧侧副韧带断裂1例。术前HSS（hospital for special surgery）评分36-58分，平均48．6分；术前膝关节屈曲活动度21～80°，平均57．4°。结果术后患者均获随访7个月～3年，平均23．6个月。无下肢静脉血栓形成或肺栓塞，无腓总神经麻痹、骨折或伸膝装置断裂等并发症发生。1例患者术后3个月出现迟发感染，再次手术取出假体，应用抗生素骨水泥间隔行膝关节旷置待二期置换。其余16例最后随访时，HSS评分78～98分，平均91．1分，较术前平均增加45．5分，且差异有统计学意义（P〈0．05）；术后2周，膝关节屈曲活动度为75～100°，平均85．2°，最后随访时膝关节屈曲活动度为85～123°，平均108．3°，与术前比较差异有统计学意义（P〈0．05）。结论旋转铰链型人工膝关节置换术近期疗效肯定，远期疗效尚待进一步随访。
Objective To discuss short-term effect of rotating hinge knee prosthesis. Methods 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 41 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° to 80° with an average of 57.4°. Results 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° to 100° with an average of 85.2° at 2 weeks postoperatively. The flexed motion range of articular was 85° to 123° with an average of 108. 3°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）. Conclusion The short-term outcome of rotating hinge knee prosthesis is good and a long term follow-up is necessary.
