DonJoy S.E.R.F. Strap Information

The DonJoy S.E.R.F. Strap is the revolutionary change in the way doctors' deal with patellofemoral pain. Traditional treatment of patellofemoral pain (PFP) has been based on the premise that abnormal patellar tracking and/or malalignment is the primary cause of symptoms. While this theory may hold true in some instances, it is not always the case. In fact, the true cause of PFP remains somewhat controversial...until now.

Rreasarch conducted by Dr. Christopher Powers at the University of Southern California has suggested that abnormal patellar tracking may be the result of excessive internal rotation of the femur (i.e. the femur moving under the patella). Donjoy and Dr. Powers have worked together to create a brace that treats the patient's condition at the source... The hip. The S.E.R.F. Strap stabilizes the patellofemoral joint and reduces pain through external rotation of the femur.
