- Primary Outcome Measures
Name Time Method <br> Cartilage measurements<br> Structural changes of the tibiofemoral and patella cartilage will be revealed by Magnetic Resonance Imaging (MRI) at 1.5T magnetic field strength. The combination of two techniques will be used, T2 relaxation time, indexing the collagen component of cartilage, and dGEMRIC, reflective of glycosaminoglycan concentration, volumetric MRI assessment of cartilage thickness and morphology. Also, the quality of subchondral bone will be evaluated. In our laboratory, the reproducibility of bulk dGEMRIC is good (CVrms 4.2 ?4.8%)<br><br> Body composition:<br> Dual energy X-ray absorptiometry (DXA) will be performed to assess body composition. The body fat, lean body mass as well as femoral neck and lumbar spine areal bone mineral density (BMD, g/cm2) and bone mineral content (BMC, g) will be analyzed.<br>
- Secondary Outcome Measures
Name Time Method <br> 1. Knee pain will be evaluated by a 100 mm visual analog scale (VAS)<br> 2. Physical function and clinically-important symptoms will be evaluated by Knee Injury and Osteoarthritis<br> 3. Knee Injury and Osteoarthritis Outcome Score (KOOS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)<br> 4. X-ray (weight-bearing anteroposterior and mediolateral radiographs) will be taken from both knees for the classification of osteoarthritis of the knee<br> 5. Quality of life will be evaluated by the RAND 36-Item Health Survey questionnaire<br> 6. Muscle strength (leg extension and flexion) will be measured using an adjustable dynamometer chair (Good Strength; Metitur, Jyväskylä, Finland)<br> 7. Muscle power will be measured with a Nottingham powerrig<br> 8. Dynamic balance and agility will be evaluated with a timed figure of 8 running test<br>
