About

Patellofemoral pain syndrome is a common source of anterior knee pain. The causes of PFPS may be multifactorial such as biomechanical disorders, muscle weakness which affect the dynamic stability of lower limb and alter patellar tracking in trochlear groove. Moreover, the syndrome associated with muscular tightness of iliotibial band, gastrocnemius, soleus, hamstring and quadriceps. Strengthening and stretching exercises are effective in improving patient's symptoms. However, they do not sufficient in correction of kinematic changes associated with PFPS. Patellar mobilization is effective in improving patient'symptoms in cases with PFPS. However, studies that conducted patellar mobilization were either low quality studies or no study combined patellar mobilization with hip and knee exercises.

Therefore, APTA guidelines recommended for conducting high quality study to investigate the effect of adding patellar mobilization to exercise therapy to support the definite recommendation delivered to therapists.

Full description

this is interventional study in which patients will receive stretching and strengthening exercises in control group. in addition, experimental group will receive the same exercises of control group in addition to patellar mobilization, retinacula release and deep friction message.
