[Chondropathy of the patella. Experiences with 100 medializations].

After a brief reference to the biomechanics of the patellofemoral joint, the anamnesis and the clinical and the radiologic symptomatology of chondropathia and the possibilities of its therapy are described. Patellofemoral arthrography is very helpful for the diagnosis. The technique of our operation is also described. After close study of current available literature and careful control of our 100 medialization cases, the results after 6, 12, 24, and 36 months are shown in tabular form. The operation is recommended for primary chondropathia patellae with lateroposition or lateral-tipped patella.
