Brief Summary

The participants will be prepared for image-capture data collection by putting four squared markers, each 4 cm in diameter, will be attached to their leg at three locations while the subject in this position: (1) proximal to a quarter of the distance along a line joining the greater trochanter to the lateral knee joint line, (2) over the neck of the fibula, (3) over the proximal part of the lateral malleolus. A fourth marker will be attached over the iliotibial tract adjacent to the superior border of the patella when the subject in a sitting position. Each participant will seat on the end of an orthopedic assessment plinth and blindfolded . Each subject will be asked to extend his/her leg and make two angles arbitrarily from the resting position (90º) to the full extension. Photos will be taken, while they keep their leg at each position for five seconds.The bubble inclinometer will be attached to the patient leg at the resting position 90 º knee flexion. The tested leg will be passively moved by the researcher through 20° to 60° of knee extension from a starting knee angle of 90° to a target angle which will be measured by the bubble inclinometer , the participant then actively held the leg in this position for 5 second. A photograph of the leg in the target position will be taken using the camera which will be positioned 185 cm from the subject and 65 cm from the ground The leg will then be passively returned to the starting angle, and the participant will be instructed to actively move that leg to the target angle and hold it in this position another photograph will be taken, and the participant will be instructed to move the leg back to the starting position , the process will be repeated 3 times for each target angle with rest time 5 seconds between shots. After completing the procedure for all subjects, the test and replicated angles will be measured using the AutoCAD software and determine the center of the markers. Also , same angles will be measured via clinometer smart phone application in those patients to assess its validityand reliability where the participant will hold the leg for five seconds for each angle where this process will be reapeated for three times for each angle.

Sampling MethodNon-Probability Sample
Study Population

1. Anterior or retropatellar knee pain from at least 2 of the following Activities : (1) prolonged sitting; (2) stair climbing; (3) squatting; (4) running; (5) kneeling; and (6) hopping/jumping. 2. Insidious onset of symptoms unrelated to a traumatic incident. 3. Age of the subject 18-35 years to limit the possibility that PFPS over age 35 may have been complicated by arthritic changes, and also the subjects should have closed epiphyseal growth plates. 4. Patient with chronic PFPS (pain \> 3 months
