KNEE 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.
