膝关节人工单髁置换的近期疗效分析

目的:探讨膝关节人工单髁置换治疗晚期膝关节单间室骨性关节炎的近期疗效。方法:选择2007年3月至2011年9月我院采用膝关节人工单髁置换且随访超过2年的单间室病变的骨性关节炎的患者37例,采用膝关节人工单髁置换治疗,随访时行膝关节X线摄片检查,观察有无松动、下沉及另外一侧间室有无退变或是否加重,末次随访时评估HSS评分,比较与术前的疼痛及功能的差异。结果:37例患者均获得随访,随访时间22~38个月,平均29.8个月,所有患者均无松动、下沉及另外一侧间室退变或退变加重,末次随访时HSS评分(95.5±1.7)分,显著高于术前(68.5±2.1)分,差异有统计学意义(P=0.016)。结论:膝关节人工单髁置换手术治疗晚期膝关节单间室骨性关节炎创伤小,患者并发症少,术后功能恢复良好,近期疗效好。

Analysis of the Short-term Efficacy of Artificial Unicompartmental Replacement of Knee

Objective:To explore the short-term efficacy of artificial unicompartmental replacement of knee in the treatment of advanced unicompartmental knee artificial replacement.Methods:37 cases of dvanced unicompartmental knee artificial replacement who were treated by artificial unicompartmental replacement and had been followed-up for more than 2 years from March 2007 to September 2011 were selected. X-ray of knee joint, wobbles, sinking and the other side compartment for any degenerative were observed. HSS score in the last follow-up, and the difference of pain and function were compared between bwfore and after operation.Results:All of 37 patients were followed-up, the time of follow-up was 22-38 months, on average 29.8 months, there was no aggravation of loosery, subsidence and the other side compartment degeneration or degeneration. HSS score was 95.5± 1.7 in the last follow-up, which was significantly higher than that before surgery(68.5± 2.1). The difference was statistically significant(P=0.016).Conclusions:Knee artificial unicompartmental replacement surgery possessed less invasive, fewer complications, quick recovery and good term efficacy, good function and good short-termoutcome.
