Patellofemoral Pain

Patellofemoral Pain (PFP)

PFP is one of the most common disorders of the knee affecting as many as 22% of the general population (Powers, Souza & Fulkerson, 2009)

70% to 90% of individuals with PFP have recurrent or chronic pain (Davis & Powers, 2010)

Research suggests that having PFP as a younger individual may predispose one to develop patellofemoral osteoarthritis later in life (Davis & Powers, 2010)

What is PFP?

-Refers to general or specific symptoms or pain and discomfort under and/or around the patella in one or both knees

– Tends to worsen with activity, while descending stairs and after long periods of inactivity

Causes of PFP

  • Pain can arise from various structures in and around the knee but the causes can be global, arising from the hip or as far as the foot
  • Misalignment of lower extremity including hip, knee and foot
  • Shape and location of patella leading to poor patellar tracking
  • Increased Q angle (angle from a line formed from the ASIS to the center of the patella, bisected by a line from the tibial tubercle to the center of the patella)
  • Tight lateral retinaculum
  • Incorrect firing patterns or decreased muscle strength in lower extremity

What can physiotherapy provide?

  • A rehabilitation program that is specific to the patient and that serves to correct or improve individual impairments. Evidence suggests that PFP is multifactorial in nature, and as a result, it is important to conduct a comprehensive assessment of potential contributing factors, including the hip, knee, ankle and lumbar spine.
  • A comprehensive program of physiotherapy rehabilitation that includes:
    • Exercise program of muscle retraining, stretching and strengthening, gait re-education
    • Modalities including acupuncture, and education for appropriate pain control
    • Manual therapy such as muscle release, patella mobilizations and taping
