PFC—Sigma固定平台和PFC—Sigma旋转平台人工膝关节应用的早期临床疗效

目的：探讨固定平台膝关节假体和旋转平台膝关节假体的临床疗效。方法：2010年1月～2011年3月，分别接受PFC—Sigma固定平台假体和PFC．Sigma旋转假体置换的患者共66例（83膝），其中男13例、女53例，年龄27～89岁，平均64岁。术后随访并根据HSS评分、生存质量评分系统、关节活动度、最大屈膝度数评价临床效果，数据采用SPSS13．0统计软件分析。影像学评估采用Centricity Enterprise WebV．30专业图像分析软件。结果：66例均获得随访，随访时间12～24个月，平均18个月。疼痛评分由术前（7．19±2．21）分提高至（26．25±2．68）分（P〈0．05），HSS评分由术前（43．28±6．72）分提高至（87．50±5．00）分（P〈0．05），活动度由术前（74．26±19．32）°提高至（115．74±11．44）°（P〈0．05），最大屈膝度数由术前（111．40±10．22）°提高至（115．7±11．44）°（P〈0．05），生存质量评分由术前（44．63±7．30）分提高至（83．99±4．36）分（P〈0．05）。影像学评估假体对位、对线良好，无假体松动。结论：合理选择膝关节假体，熟练运用TKA技巧及早期康复功能训练，可使患者获得较好的早期临床效果。

Application and Early Clinical Analysis of Total Knee Replacement with PFC-Sigma Fixed - platform Prosthesis and PFC-Sigma Rotating-platform Prosthesis

Objective：To analyze the clinical effect of fixed-platform and rotating-platform knee pros- thesis. Methods：From Jan. 2010 to Mar. 2011, a total of 66 patients （83 knees） were treated with PFC-sigma fixed-platform prosthesis or PFC-Sigma rotating-platform knee prosthesis. Among them, 13 males and 53 females, aged from 27 to 89 years （average, 64 years）. All the patients were followed up by the HSS knee rating score system, quality of life rating score system, the range of motion, the maximum knee flexion degree. All the results were analyzed by SPSS 13.0. Radiographic results were analyzed by Centricity Enterprise Web V. 30 professional image analysis software. Results： After a mean follow - up survey of 18 months （ from 12 to 24 months） ,the score of pain assessment increased from （7.19±2.21 ） before operation to （26.25 ±2.68） after operation（ P 〈 0.05 ）, the Score Hospital for Special Surgery was improved from （ 43.28± 6.72） to （ 87.50 ± 5.00） （ P 〈 0.05 ）, the rang of knee joint movement was improved from （ 74.26 ± 19.32 ） o to （ 115.74 ± 11.44） ° （ P 〈 0.05 ）, the maximum knee flexion degree was improved from （ 111.40 ± 10.22）° to （ 115.74 ± 11.44） ° （P 〈 0.05 ）, the score of quality of life improved from （44.63 ± 7.30） to （ 83.99 ± 4.36 ） （ P 〈 0.05 ）. Radiographic assessment showed that the knee prosthesis had a good alignment on the line and no prosthesis loosening. Conclusions： Reasonable selection of knee joint prosthesis, the application of skilled technology and the early rehabilitation make patients have good early clinical effect at short - term follow - up.
