[Surgical treatment of chondromalacia patellae according to Maquet/Bandi--indication, technique, results (author's transl)].

Degenerative changes of the femoropatellar joint are being observed increasingly more often. These may be due to various disturbances of the gliding movement and gliding plane. The article describes the clinical and x-ray symptoms and the therapy; in most cases, additional surgery will be necessary besides antepositioning according to the technique described by Bandi.--Follow-up examinations of 32 patients showed that in 28 of 35 surgically treated knee joints, a positive influence had been exercised on the complaints, load capacity and walking distance.
