Abstract:Objective To investigate the effect of total knee arthroplasty on knee joint function score (HSS), visual simulation score (VAS) and anxiety self-rating scale (SAS) score in patients with knee osteoarthritis. Methods From January 2016 to January 2018, 116 patients with knee osteoarthritis who were admitted to our hospital were selected as the study objects. They were divided into observation group and control group by random draw. The control group was treated with arthroscopic removal and the observation group was treated with total knee arthroplasty. All patients were followed up for 6 months. HSS, VAS and SAS scores, efficacy and quality of life of the two groups were compared before and after surgery. Results The excellent and good rate in the observation group was 91.38% (53/58), which was higher than 72.41% (42/58) in the control group (P?0.05). HSS scores of the observation group were higher than those of the control group, while VAS and SAS scores were lower than those of the control group (P?0.05). The scores of SF-36 scales in the observation group were higher than those in the control group (P?0.05). Conclusions The application of total knee arthroplasty in patients conforming to indications with knee osteoarthritis, is beneficial to improve the knee function of patients, reduce pain, improve the anxiety, and improve the quality of life, which is worthy of clinical promotion and application.
