What causes patellofemoral pain syndrome?
The true underlying cause in any one patient may be remote - such as a bony rotation in the hip or thigh, or even a structural problem in the foot and ankle - any of which can put pressure on the patella (kneecap) area because the patella is the pulley through which any abnormal lower limb forces pass.
Peer-reviewed papersQuote from peer-reviewed paper:
Patellofemoral pain syndrome "...includes an amalgam of conditions that are typically non-traumatic in origin....[and]....[e]xercise therapy, including hip, knee, and core strengthening as well as stretching and aerobic exercise, are central to the successful management...."

Pain may of course also be a result of local issues, such as -
- tight structures at the side of the kneecap causing it to tilt, eg a tight lateral retinaculum
- a patellar tendon attached to the tibia too far to the side, and putting stress on the patella
- constitutional ligament laxity, allowing the patella to frequently sublux
- an irritated fat pad
- a synovial plica being nipped between patella and femur
- an inflamed and impinging fat pad under the patella
- inflammation of the synovial lining of the joint
How is patellofemoral pain syndrome managed?
Management begins with a full assessment of the patient, looking from the lower back to the feet for all those structural issues that may be putting strain on the pulley system of the patella.
Correction of alignment may include shoe inserts, core strengthening, building muscle strength and balance, patellar mobilisations, stretches.
Surgery should not be considered until all physiotherapy and orthotic options have been exhausted.
