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?
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.
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.
Parallel
Popliteus Muscle Release
Other interventionthe participant will lie supine and relaxed on a treatment bench. The therapist will begin the treatment by flexing the participant's knee to approximately 15-25 degrees. Then, the therapist will apply pressure to the popliteus muscle while simultaneously extending the knee to approximately 5 degrees of flexion. When the knee is extended, the pressure will be released. The therapist will repeat this procedure for up to 2 minutes plus tradional therapy
Patellofemoral Mobilization
Other interventionFollowing the clinical guidelines established by Brukner and Khan, the mobilization will be performed with the patient in a supine position to ensure complete relaxation of the quadriceps musculature, thereby minimizing joint compressive forces. The intervention will include multidirectional glides tailored to specific functional deficits:Superior glides,Inferior glides,Medial-lateral excursions and tilt mobilization.Each mobilization will be applied as a gentle sustained glide for duration of 30 to 60 seconds per repetition
traditional therapy
Other interventionpatients will receive quadriceps muscle strength, hip extension strength, hamstring stretch.
pain intensity
The scale used will be the visual analogue scale (VAS), which consists of a line, usually 10 cm long, the patient will be instructed to place a vertical mark on to indicate his/ her pain, ranging from no pain or discomfort (0), to the worst pain that could possibly feel
knee disability
The Kujala Arabic version will be used to assess knee disability. it is 13 items on the scale are used to assess subjective symptoms and functional restrictions. A score can have a minimum of 0 points or a maximum of 100 points.Lower scores reflect greater pain and disability
quadriceps muscle strength
A handheld dynamometer will be used to assess quadrecips muscle strength
