Seven patients of chondropathia patellae and patello-femoral arthrosis were operated by ventralisation of tibial tuberosity during 1974 to 1976. Their average length of follow-up was 1.8 years and the maximum was 3 years after operation.
All knees of these patients were characterized by either malalignment (patella subluxation, patella alta) or a history of a blow the knee cap.
In arthroscopic examination, cartilagnous surface of the patella showed degenerative changes of various forms.
This operation gave satisfactory results in all cases with regardless of age, the severity of preoperative symptoms and x-ray findings.
It is supposed that the indication of this operation could include not only early stage of patello-femoral arthrosis but also severe stage.
