旋转平台型假体在全膝关节置换术中的临床应用

Clinical application of rotating platform knee prosthesis in the total knee arthroplasty

目的：探讨旋转平台型假体Gemini MK Ⅱ在全膝关节置换术中的临床应用及早期疗效。方法2010年8月~2013年7月采用旋转平台型膝关节假体Gemini MK Ⅱ对87例（106膝）病变膝关节行人工全膝关节表面置换术。患者年龄52~81岁，平均65.3岁，采用HSS膝关节评分系统和X线检查对临床效果进行评价。结果本组患者平均随访时间为24.2个月（7~40个月）。术后患者膝关节疼痛明显缓解或消失，关节功能得到改善。 X线检查未发现有骨溶解、假体松动或旋转衬垫脱位等并发症。 HSS评分由术前（51.5±9.7）分提高到术后（87.3±6.4）分，差异有统计学意义（P〈0.01）。结论旋转平台型膝关节假体Gemini MKⅡ用于全膝关节置换术短期临床效果令人满意，其长期效果还需要进一步观察。

Objective To research clinical application of rotating platform knee prosthesis Gemini MK II in the total knee arthroplasty. Methods From August 2010 to July 2013, 87 patients （106 knees） underwent total knee arthroplasty using rotating platform knee prosthesis Gemini MK II. The average ages of the cases were 65.3 years （52-81 years）. The clinical results were evaluated by the HSS knee rating score system as well as X-ray films. Results The patients were followed up for mean 24.2 months （7~40 months）. The pain caused by the illness of knee obviously alleviated and the function of knee significantly improved. The complications such as osteolysis around the prosthesis, prosthesis loos-ening and dislocation of meniscus bearings were not found. The HSS knee rating score was （51.5±9.7） before total knee arthroplasty, which improved to （87.3±6.4）, The difference was significant（P〈0.01）. Conclusion There are satisfactory results in a short time for rotating platform knee prosthesis Gemini MK II in the total knee arthroplasty. A long term follow-up is obviously necessary to make more precise statement about the knee replacement system.
