Abstract:

BACKGROUND: Knee society score of Peking Union Medical College 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 College. 
METHODS: Fifty-five patients with osteoarthritis of the knee were included, and the patients were divided into three groups: the preoperative group; 3 months postoperative follow-up group; 6 months postoperative follow-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 overall knee society score of the patients after 6-month follow-up was significantly improved compared with that before treatment. The knee society score after 3- and 6- month follow-up was significantly higher than that before treatment, and the score was quite with the hospital for special surgery score. The overall 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 follow-up were significantly better than those before treatment (P < 0.05); the visual analog scale score was poor after 3-month follow-up, and there was significant difference in visual analog scale score before and after treatment which was related with the pain level; the score accompanied by function and joint stiffness was significantly improved. The knee society score of Peking Union Medical College obtained four dimensions of 22 assessment projects, and the goodness-of-fit analysis showed that the scale had good goodness which had scientific nature and application value.

Key words: bone and joint implants, artificial knee joint, surface replacement, knee osteoarthritis, knee function score, followed-up, goodness-of-fit, visual analogue scale score
