Our Story

Why Was The Patellofemoral Foundation Created?

Anterior Knee Pain is very common in the general population, creating chronic disability, limitation from participation in sports, lost time from work, and generally diminished quality of life for many people of all ages. Clinicians noted that one third or more of all complaints at their sports medicine clinics were patellofemoral pain. Although these problems are common, many people with anterior knee pain never get relief. Too many never return to sports or work.

The Challenge

Despite these advances, many remain disabled and live with daily pain or discomfort. Criteria for proper treatment have been based largely on individual experience. Randomized control studies must be initiated in addition to broad-based research and education dedicated to patellofemoral disorders. There is a great need to refine the indications for anterior knee pain management and surgery, improve bracing and non-operative measures, standardize operative approaches, and develop an educational network that reaches well into the sports medicine and orthopaedic communities.


There has been some progress in the understanding of anterior knee pain. Anatomic and clinical studies have revealed sources of pain not previously recognized and opened the door to specific treatments of pain around the front of the knee. New radiologic techniques, particularly computerized tomography and MRI, have led to a greater understanding of the mechanical behavior of the patella.

A Successful Patellofemoral Treatment
  • Listen to the patients. Let them guide you to the source of pain and disability
  • Establish core lower body stability, starting at the hips
  • Maximize nonoperative treatment first, but do not overlook the patient who needs help beyond what nonoperative treatment can achieve
  • If surgery becomes necessary, always aim to restore balance without adding abnormal load, particularly to articular lesions
  • Release only what is too tight, and tighten only what is too loose
  • Unload articular lesions, restore balance Beware of medial PF instability in patients who are more unstable after surgery
  • Early controlled motion after PF surgery
