Pathophysiology
The joint where the kneecap (Patella) meets the upper leg bone (Femur) is called the patellofemoral joint, the kneecap sits in a groove here. Pain is often caused by an imbalance of the muscles that surround and support the knee; this can alter the load and positioning of the patellofemoral joint. Also known as: anterior knee pain, runner’s knee.
Symptoms
- Pain at the front of the knee, often vague and intermittent
- Pain with kneeling/direct pressure
- Often gradual onset related to increased load or activity
- May be creaking noise of the knee on movement
- Often aggravated by walking, running, stairs and deep squatting
- Swelling on acute episodes
Management
- Activity modification
- Ice or heat
- Pain relief
- Suitable footwear which provide support
- Physiotherapy including range of movement exercises and a graded strengthening programme
- Orthopaedic options - 3-6 months conservative measures unless dislocated on more than 3 occasions
