Patellofemoral joint and contact characteristic

Abstract EN

The patella form patellofemoral joint .

this joint is a complex articulations with high functional and biomechanical requirements.

Multiple clinical problems of the knee joint may caused by anatomical and physiological abnormalities of this joint.

So exact knowledge about the anatomy, the biomechanical and function of patellofemoral joint is there fore required to understand its wide rang of pathology.

So 10 patella of adult human where measured the surface area of medial and lateral articular surfaces.

The result indicated that lateral articular surface area of patella is larger than medial one.

This lead to conclusion that there is increase pathological regions on the lateral side of the knee joint, beside increasing contact area in human weight bearing and cause pain on the lateral side with increasing contact area during flexion exercise of the knee joint.
