Patellofemoral Pain Syndrome

  • Steven F. DeFroda


Patellofemoral pain syndrome is a common cause of anterior knee pain. It often affects females more frequently than males, with the most common complaint being pain posterior to the patella when ascending or descending stairs. It can be caused due to patellar maltracking, chondral injury, or early osteoarthritis. The patella is a large sesamoid bone, which transmits a great deal of force from the quadriceps across the knee and through the lower extremity. Repetitive loading of this joint can lead to micro trauma and injury in the form of chondromalacia. The primary treatment for this condition is nonoperative, with a focus on lower extremity strengthening, and symptomatic management (Crossley et al. BMJ 351:h3939, 2015).
