使用DELUXE假体及REVOLU截骨器行膝关节置换术的初步临床报告

目的探讨选用DELUXE假体及REVOLU截骨器行膝关节置换术的近期结果。方法对2008年2月至2009年4月,本组采用后稳定型固定衬垫DELUXE假体及REVOLU五合一截骨安装系统行TKA的26例31侧膝关节病变患者进行临床随访、分析。结果随访时间8～22个月,平均12.5个月。全组优良率为90.3%,HSS评分平均为（80.74±5.45）分;单侧手术时间为（74.5±5.8）min,术后切口均Ⅰ期愈合,无深部感染。X线检查证实未发现有骨溶解、假体松动或衬垫脱位等并发症。患者主观感觉满意。结论 DELUXE膝关节假体是根据国人膝关节解剖特点设计的新一代膝关节假体,改进了国外假体对国人膝关节尺寸不匹配及覆盖率不良的问题REVOLU作为一种新型五合一截骨系统,可一次同时完成股骨远端五个面的截骨,提高了截骨精确度,减少了手术时间,操作简便,近期临床疗效满意,其长期效果需要进一步观察。

Preliminary clinical outcomes of DELUXE prosthesis and REVOLU osteotomy system in knee replacement

Objective To investigate the preliminary clinical outcomes of DELUXE prosthesis and REVOLU osteotomy system in knee replacement. Methods 31 knees of 26 cases with arthropathy were treated by knee replacement with DELUXE prosthesis and REVOLU osteotomy system from Febrary 2008 to May 2009. All the patients were followed up. HSS scale was recorded and analyzed. Results All cases were followed up for eight to 22 months. The excellent and good rate was 90.3%. HSS score was (80.74±5.45) in average. The average operation time of single knee was (74.5±5.8) min. No infection was ocurred. No osteolysis, aseptic loosening or dislocation of polyethylene pad was revealed from post-operative X-ray films. All patients were satisfied. The maximum flexion of knee was 130 degrees. Conclusions DELUXE prosthesis is a good design, which referenced the anatomic data of the Chinese people’s knees. It is simple for manipulation. The surface design of the polyethylene pad conduces to less wearing and tearing. It can get better cover of the osteotomy section. REVOLU system is a new method for the osteotomy of distal femur, which can obtain five facets by one step in TKA. This system can provide a better conformity between the prosthesis and distal femur, and reduce the operation time. The preliminary clinical outcome is superior and these two devices need further investigation.
