Patellofemoral Pain Syndrome
Anatomy
Normally the patella (kneecap) has a wedge shape, with a medial and a lateral facet and a central crest. The patella slides in the intercondylar sulcus of the femur during knee flexion and extension, forming the patellofemoral joint (PFJ).
Mechanism of Injury
- Altered biomechanics due to muscle weakness and soft tissue tightness is thought to contribute to PFJ dysfunction.
Symptoms
- Pain is generally of gradual onset, is often difficult to localise, and is widespread.
- Pain is generally felt anteriorly and behind the patella during exertion or load.
- Pain and stiffness can be felt when rising to standing from a prolonged sitting.
- Local tenderness may be present on the medial or lateral patellar facets around the patella and on compression of the patella.
- Creaking during flexion and extension of the knee may be experienced behind the patella.
- Sometimes a slight swelling in the knee joint is noticeable.
Treatment
Please consult with your medical professional for a complete diagnosis and treatment plan.
