Function will be measured by the Kujala Patellofemoral Knee Score. The total score on the Kujala Patellofemoral Knee Score questionnaire can range from 0 to 100, with higher scores indicating better knee function and less impairment. General breakdown of the score interpretation:

100: No limitations or symptoms 85-99: Mild limitations or symptoms 70-84: Moderate limitations or symptoms Below 70: Severe limitations or symptoms

The single-leg hop distance is an indicator of lower extremity function. The test evaluates an individual's lower limb strength, power, and overall functional performance. It specifically focuses on assessing an individual's ability to generate power and stability while performing a single-leg hop for maximal distance. When performing the test, the individual starts by standing on one leg at the starting point. The opposite leg is lifted slightly off the ground, and the hands can be placed on the hips or kept at the sides for balance. On the command to start, the individual hops forward on the single leg, aiming to jump as far as possible while maintaining control and balance. Perform 3 repetitions and record the longest distance jumped.

Dynamic balance will be measured by Y Balance Test. The Y Balance Test involves a person standing on one leg while reaching in anterior (forward), posteromedial (backward and to the side), and posterolateral (backward and to the other side) directions with the other leg. The person places their stance foot at the starting point on the central part of the Y-shaped device.While maintaining balance on the stance leg, the person reaches the free leg as far as possible along each of the three arms of the Y.The distance reached in each direction is measured and recorded.

Static balance will be measured using a Biodex Balance System, single leg sway index test procedure. The device reports the person's body oscillations as sway index. A high stability index indicates poor postural control.
