Abstract:
BACKGROUND:Unicompartmental knee arthroplasty for osteoarthritis can be accepted by more and more scholars, but some scholars believe that total knee arthroplasty is a better choice. OBJECTIVE:To compare knee scores between patients before and after unicompartmental knee arthroplasty and total knee arthroplasty. METHODS:A total of 53 patients with knee osteoarthritis, who underwent unicompartmental knee arthroplasty in the First Affiliated Hospital of Xinjiang Medical University from March 2013 to November 2014 and obtained fol ow-up, were enrol ed in this study. Simultaneously, 53 patients, who received total knee arthroplasty in the same period and obtained fol ow-up, were selected. Knee scores before surgery and in final fol ow-up were recorded in both groups, including KSS score, WOMAC score, OKS score and HSS score. The knee maximum flexion and patient satisfaction were recorded in final fol ow-up. RESULTS AND CONCLUSION:Patents with complications were excluded in both groups. Knee scores were significantly higher in final fol ow-up than in pre-operation (P<0.05). No significant difference in knee scores was detected in final fol ow-up between the two groups (P>0.05). Maximum range of motion in final fol ow-up was significantly larger in unicompartmental knee arthroplasty group than in total knee arthroplasty group (P<0.05). Patient satisfaction was similar between the two groups. Moreover, the association between WOMAC scores and OKS scores was high. These results suggest that unicompartmental knee arthroplasty could improve patient’s quality of life as total knee arthroplasty so long as physicians grasp strict indications;standard replacement operation and good functional exercise after replacement, but its long-term outcomes stil need further investigations.
