背景：Deluxe-PS 型人工膝关节假体是根据中国人膝关节解剖特点尤其是股骨髁的形态特征而设计的，其膝关节假体股骨髁内外侧距(M-L)较进口假体少3.5 mm。 　　目的：探讨Deluxe-ps膝关节假体行一期双膝关节置换中的近期疗效。 　　方法：纳入使用Deluxe-ps型膝关节假体行一期双侧膝关节置换的膝关节炎患者15例(30膝)设为实验组，对照组为同期采用P.F.C.Sigma膝关节假体行一期双侧膝关节置换的20例患者(40膝)。采用KSS评分和关节功能HSS评分、膝关节关节活动度评估两组手术前、后膝关节功能，对比两组手术时间、及术中输血量。 　　结果与结论：两组患者置换后均得到12-24个月随访，平均16个月。置换后患者膝关节疼痛均缓解，关节功能恢复满意。两组膝关节置换后与置换前 KSS 评分、HSS 评分及膝关节关节活动度比较，差异均有显著性意义(P<0.05)。置换后，两组间KSS评分和HSS评分及膝关节关节活动度，差异均无显著性意义(P>0.05)，两组间置换过程中出血量比较，差异均无显著性意义(P>0.05)，手术时间比较，差异有显著性意义(P<0.05)。说明采用Deluxe-ps膝关节假体行一期双膝关节置换近期疗效满意。

BACKGROUND:Deluxe-PS knee prosthesis is designed based on the anatomical characteristics of the Chinese peoples’ knee joint, especial y the morphological features of femoral condyle. The distance between median and lateral knee prosthesis femoral condyle is less than that of the imported prosthesis for 3.5 mm. OBJECTIVE:To explore the short-term efficacy of Deluxe-ps knee prosthesis in simultaneous bilateral total knee arthroplasty. METHODS:Fifteen knee osteoarthritis patients (30 knees) were included as the experimental group, and treated with simultaneous bilateral knee arthroplasty by Deluxe-ps knee prosthesis. Twenty patients (40 knees) in the control group were treated with simultaneous bilateral knee arthroplasty by PFCSigma knee prosthesis. The knee society score, hospital for special surgery knee score and knee joint range of motion were compared between two groups;the operation time and the intraoperative blood loss were compared between two groups. RESULTS AND CONCLUSION:The patients in both groups were fol owed-up for 12 to 24 months, with an average of 16 months. Postoperative knee pain was relieved, and the joint function was recovered satisfactorily. The knee society score, hospital for special surgery knee score and knee joint range of motion in two groups were improved significantly after treatment (P<0.05). There were no significant differences in postoperative knee society score, hospital for special surgery knee score and knee joint range of motion between two groups (P>0.05), and there was no significant difference in intraoperative blood loss between two groups (P>0.05), while there was significant difference in operation time between two groups (P<0.05). The results showed that the short-term effect of Deluxe-ps knee prosthesis in simultaneous bilateral total knee arthroplasty was satisfied.
