Total knee arthroplasty:Goodness-of-fit analysis of intraoperative knee society score of Peking Union Medical College / 中国组织工程研究

ABSTRACT

BACKGROUND:Knee society score of Peking Union Medical Col ege has been promoted and used in the 306th Hospital of PLA for 2 years and we have accumulated some clinical data. OBJECTIVE:To analyze the stability and feasibility for suitable clinical medical practice of knee society score of Peking Union Medical Col ege. METHODS:Fifty-five patients with osteoarthritis of the knee were included, and the patients were divided into three groupsthe preoperative group;3 months postoperative fol ow-up group;6 months postoperative fol ow-up group. The measurement results obtained by the application of the scale were compared to those of the Western Ontario and McMaster Universityies Ostroarthritis Index, visual analog scale, and hospital for special surgery score, and then knee society score goodness-of-fit analysis was performed based on the structural equation model. RESULTS AND CONCLUSION:Knee society score performance assessment of the signs and symptoms of osteoarthritis of the knee patients was positively correlated with the pain severity of visual analog scale score;the overal knee society score of the patients after 6-month fol ow-up was significantly improved compared with that before treatment. The knee society score after 3-and 6-month fol ow-up was significantly higher than that before treatment, and the score was quite with the hospital for special surgery score. The overal assessment of the knee society score after treated for 3 and 6 months was improved for more than grade Ⅰ, the visual analog scale score was decreased for more than 30%. The pain assessment items and physiological functional assessment items of Western Ontario and McMaster Universityies Ostroarthritis Index after 6-month fol ow-up were significantly better than those before treatment (Pgoodness-of-fit analysis showed that the scale had good goodness which had scientific nature and application value.
