KPS=knee pain scale.
Repeated measures analysis of variance compared between-group KPS scores after adjusting for baseline scores, age, sex, and body mass index.
↵a Change in dextrose score was greater than change in saline (P <.05) and exercise (P <.05) scores, and there were no statistically significant differences between saline and exercise scores.
