摘要:

背景:单髁置换越来越多的被应用于治疗单纯内侧胫股间室型膝关节骨关节炎。
目的:比较膝关节单髁置换与全膝关节置换对膝关节单纯内侧间室骨关节炎的修复效果。
方法:纳入单纯内侧间室型膝关节骨关节炎患者109例,根据修复方式分为两组,单髁置换组41例,全膝关节置换组68例。比较两组患者的平均住院时间、置换后并发症发生率、身体健康总评分、精神健康总评分、牛津膝关节评分以及置换后5年假体在位率。
结果与结论:单髁置换组患者平均住院时间(4.21±2.44) d,较全膝关节置换组(6.11±2.23) d短(P=0.001)。两组患者置换后并发症发生率、身体健康总评分、精神健康总评分、牛津膝关节评分等方面差异均无显著性意义(P > 0.05)。置换后5年,单髁置换组假体在位率(90%)较全膝关节置换组(100%)低(P < 0.05)。提示对于单纯内侧胫股间室型膝关节骨关节炎患者,单髁置换与全膝关节置换具有相似的修复效果,但单髁置换后5年假体在位率稍低。

Abstract:

BACKGROUND: Unicompartmental arthroplasty are more and more applied in the treatment of isolated medial compartment of knee joint osteoarthritis.
OBJECTIVE: To compare the repair efficacy of unicompartmental knee arthroplasty and total knee arthroplasty in the treatment of knee medial compartment osteoarthritis.
METHODS: Totally 109 patients with isolated medial compartment of knee joint osteoarthritis were enrolled, and then divided into unicompartmental arthroplasty group (n=41) and total knee arthroplasty group (n=68) according to the different repair methods. The average hospital stay, the incidence of complications after replacement, total scores of physical health and mental health, the Oxford knee joint scores and prosthesis survival rate after 5 years of replacement were compared.
RESULTS AND CONCLUSION: The average hospital stay of patients in the unicompartmental arthroplasty group ((4.21±2.44) days) was shorter than that in the total knee arthroplasty group ((6.11±2.23) days) (P=0.001). There were no significant differences in the incidence of complications, total scores of physical health and mental health, the Oxford knee joint scores and other aspects between these two groups (P > 0.05). After 5 years of replacement, the prosthesis survival rate of unicompartmental arthroplasty group (90%) was lower than that in the total knee arthroplasty group (100%) (P < 0.05). These results suggest that as for patients with isolated medial compartment of knee joint osteoarthritis, unicompartmental arthroplasty and total knee arthroplasty have similar repair effect; however, the prosthesis survival rate is a little lower after 5 years of unicompartmental arthroplasty.
