Clinical Trial Summary

Background: The effect of exercise on knee osteoarthritis (OA) is often evaluated with patient-reported scales. The Minimal Clinically Important Difference (MCID) values of these scales are needed to understand the change in patients after treatment and to manage the treatment.

It is also one of the most important data in calculating the MCID sample size. Aim: In the literature, MCID studies for exercise applied to knee OA are limited especially for those who did not undergo surgery. Thus new studies are needed.

Method: 100 patients who were diagnosed with knee osteoarthritis will be recruited for the study. Participants will be included in an exercise program tailored to their needs for 15 sessions. WOMAC, OKS, LEFS scales will be used also knee range of motion will be assessed in the baseline, after treatments and in the 4th month follow up.
