Knee Osteoarthritis, Knee Osteoarthritis (Knee OA)
Conditions
Brief summary
Knee osteoarthritis (KOA) is a common chronic joint condition leading to pain, functional limitations, and reduced quality of life. This randomized controlled trial aims to evaluate and compare the effectiveness of a structured home-based exercise program versus topical diclofenac sodium therapy in improving pain, functional outcomes, and health-related quality of life among adults with early-stage KOA. The results are intended to provide evidence on the optimal components of home-based conservative management strategies.
Interventions
Patient education + structured, video-based home exercise program Participants instructed to perform exercises 5 days per week for 6 weeks Adherence monitored via logs and telephone follow-up at week 3
Patient education + 1.5% diclofenac sodium gel Participants applied gel to anterior, medial, and lateral aspects of the knee, once daily, without massage techniques, for 6 weeks

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Numeric Pain Rating Scale (NPRS) | Baseline | Pain intensity will be measured using an 11-point numeric pain rating scale, with 0 indicating no pain and 10 indicating the worst pain conceivable. Patients will be asked to rate their knee pain's severity with a number between 0 and 10 using this scale. The minimum clinically important difference (MCID) of this validated pain scale is accepted as \>2. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) | Baseline | The assessment of functional difficulty will be measured the WOMAC index. The total score of the WOMAC ranges from 0 to 100 (lower scores representing lower level of disability), and the MCID was reported as 12 points. |
| 12-Item Short Form Survey (SF-12) | Baseline | The assessment of health-related quality of life will be measured the 12-Item Short Form Survey (SF-12). The SF-12 physical and mental scores (range 0 to 100, representing worst to best; MCID of 5) was used to evaluate health-related quality of life |
