Patellofemoral (knee) disorders are among the most common conditions managed in the orthopedic and sports medicine setting. The patellofemoral joint consists of the patella (knee cap) and trochlea (femur or thigh bone).
The differential diagnosis of anterior knee pain is extensive and usually diagnosed using medical history and a physical examination. Some of the more common pathologies seen are patellar tendinopathy, IT band syndrome, and patellofemoral pain syndrome. These injuries are more common in, but not limited to, people who participate in running or jumping activities. These pathologies are usually caused by overuse or overload.
Common knee injuries and symptoms include:
- Patellar tendinopathy
- Inferior knee pain
- Tenderness around inferior patella and patella tendon
- Common in sports involving frequent jumping
- Iliotibial (IT) band syndrome
- Lateral knee pain
- Tenderness in lateral knee
- Common in runners and bikers
- Patellofemoral pain syndrome
- Pain in or around the knee
- Increased pain with increased knee flexion with weightbearing exercises
Some risk factors include abnormal alignment, abnormal biomechanics and muscle weakness. Patellofemoral pain is treated with conservative care. This includes early reduction in symptoms, activity modification and physical therapy. If indicated, injections and imaging may be warranted.
Other differential diagnoses include Hoffa disease, lateral patellar compression syndrome, patellar instability, plica syndrome and arthritis. A thorough clinical examination will determine what tissues are involved and allow the physical therapist to prescribe appropriate exercises based on the pathology.
