Patellofemoral pain syndrome (PFPS) is a broad term used to describe pain in the front of the knee and around the patella, or kneecap.

2024年7月28日 · The patellofemoral joint is where the back of your patella (kneecap) and femur (thigh bone) meet at the front of your knee. It's involved in climbing, walking on an incline, and several other knee movements. It's also the joint affected by a …

Patellofemoral arthritis affects the underside of the patella (kneecap) and the channel-like groove in the femur (thighbone) that the patella rests in. It causes pain in the front of your knee and can make it difficult to kneel and go up and down stairs.

The patella contacts the femur with its inferior pole. At 60-90 degrees knee flexion the patella occupies the intercondylar groove. There is maximum contact between the patella and the intercondylar groove (1/3 of the posterior surface area of the patella).

The tibia bears 85% of the load during weight-bearing activities, while the fibula provides lateral stability.
