【摘要】：背景人工全膝关节置换术在临床治疗上已经成熟。高屈曲旋转平台型膝关节假体在设计上更具优势,更加接近膝关节生理结构。目的探讨应用LPS-Flex Mobile Bearing System人工膝假体(Zimmer,USA)行全膝关节置换的近期疗效。方法回顾性分析2012-02/2014-03苏州大学附属第一医院收治的行Zimmer LPS-Flex Mobile Bearing System人工膝假体置换的患者37例(42膝),男9例(10膝),女28例(32膝),年龄47-78岁,平均63.7岁;置换术前诊断:骨性关节炎35例(39膝),类风湿性关节炎2例(3膝)。采用骨水泥固定,不进行髌骨置换;观察术后并发症,比较术前、术后膝关节活动度,并根据HSS膝关节评分系统进行评估。结果获随访34例(38膝),时间6-28(平均15.14)个月。活动度从术前平均88.5改善到术后平均124.2;术前HSS评分平均为52.5分,术后HSS评分平均为91.1分;均较术前有明显改善(P0.01)。根据HSS评分系统评定疗效:优20例,良16例,中2例,优良率达94.74%。各种并发症的发生率低。到最后一次随访为止,所有病例均未出现下肢深静脉血栓形成、假体周围骨折、髌骨撞击等并发症。置换后随访X射线片均未显示任何骨溶解、关节脱位、假体-骨界面的X射线透亮带、以及与松动相关的假体力线改变等X射线征。结论高屈曲旋转平台型人工全膝关节置换的近期临床效果满意,长期效果还需进一步观察。
[Abstract]:Background Total knee arthroplasty is mature in clinical treatment. The high-flexion rotary platform knee prosthesis has more advantages in design and is closer to the physiological structure of the knee joint. Objective to investigate the short-term effect of total knee arthroplasty with LPS-Flex Mobile Bearing System artificial knee prosthesis (Zimmer,USA). Methods A retrospective analysis was made on 37 patients (42 knees) treated with Zimmer LPS-Flex Mobile Bearing System prosthesis replacement in the first affiliated Hospital of Suzhou University, 2012-02 / 2014-03, including 9 males (10 knees) and 28 females (32 knees), aged 47-78 years (mean 63.7 years). 35 cases (39 knees) of osteoarthritis and 2 cases (3 knees) of rheumatoid arthritis were diagnosed before replacement. Using bone cement fixation without patellar replacement, the postoperative complications were observed, the preoperative and postoperative knee motion were compared, and evaluated according to the HSS knee scoring system. Results 34 cases (38 knees) were followed up for 6-28 months (mean 15.14 months). The average range of activity was improved from 88.5 before operation to 124.2 after operation, the mean HSS score was 52.5 before operation, and the average HSS score after operation was 91.1, which was significantly improved compared with that before operation (P0.01). According to the HSS scoring system, 20 cases were excellent, 16 cases were good, 2 cases were fair, and the excellent and good rate was 94.74. The incidence of various complications was low. Up to the last follow-up, there were no complications such as deep vein thrombosis, periprosthetic fracture and patellar impact in all cases. There were no X-ray signs such as osteolysis, dislocation of joint, X-ray clear zone at the prosthetic bone interface, and pseudo physical force changes associated with loosening. Conclusion the short-term clinical effect of high-flexion rotation platform total knee arthroplasty is satisfactory, and the long-term effect needs further observation.
