[Femoropatellar joint. Aspects of anatomy, physiology and pathophysiology].

The variety of anatomic conditions is critically confronted with the so-called dysplasias of the patella. Is chondromalacia or anterior knee pain a clinical diagnosis? The physiological aspects of the tension forces acting on the patella with its position in the midst of tendons and ligaments in valgus and in varus knees are discussed.
