Popliteus Muscle Release Versus Patellofemoral Mobilization in Patellofemoral Pain Syndrome

This study will be conducted to compare the effect of popliteus muscle release and patellofemoral mobilization on pain intensity, function, and quadriceps muscle strength in patients with patellofemoral pain syndrome?

Inclusion Criteria: * Male and female participants aged 18-30 years. * minimum history of 3 months of unilateral PFP. * pain intensity score of ≥3 on a 10-cm Visual Analog Scale (VAS) for worst pain experienced during the previous week. * Pain reproduced during at least two of the following functional activities: stair ascent or descent, running, hopping, prolonged sitting, squatting, or kneeling. * Presence of pain on at least one of the following clinical tests: patellar compression test or palpation of the patellar facets. Exclusion Criteria: * Clinical, x-ray, or MRI findings indicative of other specific pathology including osteoarthritis, meniscal, ligament or cartilage injury, apophysitis. * Recurrent patellar subluxation or dislocation. * Cortisone use over an extended period of time. * Previous surgery to the knee joint; trauma to the knee joint affecting the presenting clinical condition. * Lower limb deformities.
