全膝关节置换术与单髁置换术治疗老年膝关节骨关节炎的疗效比较

目的:探讨全膝关节置换术与单髁置换术对老年膝骨关节炎患者的临床疗效及术后恢复情况。方法:收集我院就诊的94例膝骨关节炎患者,随机分为UKA组和TKA组,每组各47例。UKA组采用单髁置换术治疗,TKA组采用全膝关节置换术治疗。观察并比较两组患者治疗前后膝关节功能评分(KSS)、疼痛视觉模拟评分(VAS)以及手术时间、术中出血量及术后并发症的发生情况等。结果:与治疗前相比,治疗后两组患者KSS评分均升高,VAS评分均下降,差异具有统计学意义(P0.05);与TKA组相比,UKA组VAS评分水平较低,KSS评分水平较高,差异具有统计学意义(P0.05);与TKA组相比,UKA组手术时间短,术中出血量少,差异具有统计学意义(P0.05);两组患者治疗后的并发症发生率差异无统计学意义(P0.05)。结论:在掌握适应证的前提下,与全膝关节置换术相比,单髁置换术创伤小、出血量少,关节功能恢复较好。

Comparison of Clinical Efficacy of Total Knee Arthroplasty and Single Condyle Replacement in Treatment of Knee Osteoarthritis for Elderly Patients

ABSTRACT Objective: To investigate the clinical effect of total knee arthroplasty and unicompartmental knee arthroplasty on the treatment of knee osteoarthritis for elderly patients. Methods: 94 cases with knee osteoarthritis who were treated in our hospital were se- lected and randomly divided into the UKA group and the TKA group, with 47 cases in each group. The patients in the UKA group were treated with unicompartmental knee arthroplasty, while the patients in the TKA group were treated with total knee arthroplasty. Then the knee score (KSS), visual analogue scale (VAS), the operation time, blood loss and the incidence of postoperative complications of pa- tients in the two groups were observed and compared before and after the treatment. Results: Compared with before treatment, the KSS scores in the two groups increased, while the VAS scores decreased after the treatment, and the differences were statistically significant (P<0.05); Compared with TKA group after treatment, the VAS score in the UKA group was lower, and the KSS score was higher, and the differences were statistically significant (P<0.05); Compared with TKA group, the time used for operation in the UKA group was shorter, and the quantity of bleeding was lower, and the differences were statistically significant (P<0.05); There was no statistically sig- nificant difference about the incidence of postoperative complications between the two groups (P>0.05). Conclusion: Compared with total knee arthroplasty, the unicompartmental knee arthroplasty had less invasive and bleeding and better recovery of joint function on the condition that the mastering indications of patients were clearly.
