What Is Patellofemoral Pain Syndrome?
Patellofemoral Pain Syndrome also commonly known as PFPS is a general term for anterior knee pain or discomfort.
Usually arises from increased contact of the posterior surface of the patella with the femur or inflammation of structures around the patella.
What causes PFPS? The cause of PFPS is usually from
malalignment or biomechanical dysfunction with the patellofemoral joint.
According to Mascal and Powers, this includes impairments that cause an increased functional Q-Angle such as: Femoral anteversion, external
tibial torsion, genu valgum, foot hyperpronation, or increased hip flexion and adduction.
There may also be a tight retinaculum, weak VMO, patella alta, patella baja, or dysplastic femoral trochlea.
All these can predispose the person to abnormal patellar tracking, which increase contact forces between patella and femur, increase pull on patellar tendon, or inflamed fat pads or bursa, thus causing the pain.
Signs & Symptoms Pain or poor control
when ascending or descending stairs.
Pain with walking, running, and jumping.
Pain and stiffness associated with prolonged sitting and squatting.
Grating and grinding under patella with movement.
Current Treatment Protocol
There is none because every patient has different causes of PFPS.
Most included strengthening muscle and stretching muscles and soft tissue around the knee.
Selectively Strengthening the VMO
