aJapanese Knee Osteoarthritis Measure:
JKOM I evaluates the pain component, with patients indicating their pain level on a continuous scale from 0–100, where 0 indicates "no pain at all" and 100 indicates "the most severe pain ever experienced"
JKOM II to V are for knee function components. JKOM-II asks eight questions about knee pain and stiffness, JKOM-III asks ten questions about activities of daily living, JKOM-IV asks five questions about general activities that require leaving the house, and JKOM-V asks two questions about the patient’s perception of their overall health and the contribution made by knee symptoms. Patients rate each of the 25 questions on a five-point Likert scale, with 0 indicating “best” and 4 indicating “worst”. A total score of 0 indicates little loss of function, while a total score of 100 indicates severe loss of function
Values were generated with two-sample two-tailed Student’s t-test and Fisher’s exact test. A p value < 0.05 was considered significant
