title: [Diagnosis and operative treatment of chondromalacia patellae by osteotomy and ventral or ventral and medial transposition of the tuberositas tibiae (Maquet/Bandi-procedure) (author's transl)].
abstract: The clinical picture of chondromalacia patellae is outlined by the patellar syndrome. The diagnostic value of double contrast arthrography by tangential X-ray (skyline-view)-technique of the femoro-patellar-joint is stressed. If conservative treatment is not satisfactory, osteotomy and ventral transposition of the tuberositas tibiae should be performed. When the patella and the extensor apparatus are dislocated laterally, it is necessary to displace the tuberositas in medial direction. From 1976 to 1980 159 patients have been treated this way. Follow-up study in 86 cases (1 to 5 years after operation) shows excellent and good results in a percentage of 77.
