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.

Product Questions

I am hypermobile (Ehlers-Danlos) and have partial labral tears in both hips which I am trying to prevent from becoming complete. My legs rotate inward due to lax connective tissue which causes my hips try to sublux. This does cause me mild knee pain and patellar popping. Can I wear the strap on both legs or do they make one that helps both legs at once? Will this help my situation- prevent subluxation of the hips, further completeness of labral tears, and knee discomfort?

Janet
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

If i have dislocated my knee cap and i am in volleyball, i wanted to know if this would be good for my knee. I really need a knee brace but i cant find one. Would this be good?
Question by: Katie on Jul 21, 2011, 7:13 PM
This brace is a great tracking brace, but it is not the best for Dislocation patellas. I would suggest looking at either the Tru-pull Lite, or the Tru-pull Advanced system, either of these will be a better choice for you.
