摘要
目的探讨半限制性膝关节假体（LccK）在晚期类风湿性关节炎伴严重膝内翻畸形患者施行初次膝关节置换中应用的方法和疗效。方法应用LCCK对我院关节外科在2012年2月至2014年9月收治的20例晚期类风湿性关节炎伴严重膝内翻患者施行初次膝关节置换。结果所有患者在3个月～2年复查时膝关节正侧位片显示假体位置良好，体检膝关节屈曲畸形均小于5°，关节活动度均超过100°，关节稳定性好，内外翻应力试验阴性。结论晚期类风湿性关节炎伴严重膝内翻患者膝关节韧带功能不全，随着类风湿病变进展，若使用非限制性假体施行表面置换早期发生膝关节不稳者较多，此时应考虑使用半限制性假体。
Objective To discuss the effect and the application of LCCK in the primary TKA with advanced rheumatoid arthritis and severe varus knee. Methods A total of 20 cases of advanced rheumatoid arthritis with severe varus knee were se- lected from February 2012 to September 2014 in the joint surgery in our hospital. These patients were operated with primary TKA using LCCK. Results All cases were followed up in 3 months to 2 years. The X-ray of the postoperative prosthesis posi- tion was good. In the physical examination of all the cases, the flexion deformity of the knee was less than 5° and knee active range of motion was more than 100°. The stability of the knee was good, both valgus and varus test under stress were negative. Conclusion The ligament funtion of advanced rheumatoid arthritis patients with severe varus knee is insufficient. With the pro- gress of rheumatoid disease, the early instability of the surface replacement of the knee with the unconstrained prosthesis is more, which happened especially on the coronal plane of tibiofemoral joint. At this time, the constrained condylar of the knee prosthesis should be considered.
