| Measure | Description | Time Frame |
|---|---|---|
| Pain intensity | Pain intensity will be measured using the numerical pain rating scale. Patients are asked to circle the number between 0 and 10 that fits best to their pain intensity. Zero usually represents 'no pain at all' whereas the upper limit represents 'the worst pain ever possible'. | 6th week |

Zero usually represents 'no pain at all' whereas the upper limit represents 'the worst pain ever possible'. | 3rd month |
| Function | Functional status of the patients will be evaluated by The Western Ontario and McMaster Universities Arthritis (WOMAC) Index. It is a self-administered questionnaire consisting of 24 items divided into 3 subscales (Pain, Stiffness and Physical Function). The test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4). Higher scores on the WOMAC indicate worse results. | 6th week |
| Functional performance - 40m fast-paced walk test | Functional performance of the patients will be evaluated by 40-meter fast-paced walk test. Participants are asked to walk as quickly but as safely as possible, without running, along a 10-meter walkway for a total distance of 40 meters. Walking speed will be measured in meters/second (m/s). | 6th week |
| Functional performance - 10-step stair-climb test | Functional performance of the patients will be evaluated by 10-step stair-climb test. Patients are instructed to ascend and descend the flight of stairs as quickly as possible but in a safe manner. The time needed is recorded in seconds. |
| Measure | Description | Time Frame |
|---|---|---|
| Range of motion | Knee joint ROMs will be measured using a universal goniometer. The process will be repeated three times and the average value will be recorded. | 6th week |
