An Approach to Managing Patellofemoral Pain
Developed in conjunction with Dr. Christopher Powers at the University of Southern California, the S.E.R.F. Strap™ is the FIRST patellofemoral brace designed to help alleviate patellofemoral pain stemming from abnormal hip motion(s). The S.E.R.F. Strap™ utilizes a unique 3-point hip-leg anchor to help alleviate patellofemoral pain caused by excessive hip internal rotation, adduction, and/or knee valgus. Made of thin Breathe-O-Prene®, the S.E.R.F. Strap™ is lightweight, breathable, and designed to be worn underneath clothing. The S.E.R.F. Strap™ can be used to control abnormal hip motion during leisure/sport activities and as a training tool in the clinic. The DonJoy S.E.R.F. Strap™…Ride the wave of change!
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 etiology of PFP remains somewhat controversial… until now.
Research 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). 1dj Ortho has worked with Dr. Powers to create a brace that supports alignment of the hip. The S.E.R.F. Strap™ stabilizes the patellofemoral joint and reduces pain through external rotation of the femur.
The S.E.R.F Strap™ is the first patellofemoral brace designed to help alleviate PFP stemming from abnormal hip motion(s). If you suspect that your patient’s PFP is related to poor proximal control, the S.E.R.F Strap™ is the right choice. The S.E.R.F. Strap™ can be used to control abnormal hip motion during leisure/sport activities and can be used as a training tool in the clinic.

The SERF Strap will rotate the hips outward, so this will prevent hip internal rotation and should help with the subluxation. You can wear straps on both hips
