Summary

Fifty-one knees with patellofemoral symptoms, but with normal conventional radiographs, were studied by CT-scan. All but five showed evidence of malalignment, and when operated on had an abnormality of the articular cartilage. The authors conclude that in many cases a CT-scan is the best diagnostic procedure for the evaluation of disorders of the patellofemoral joint.

Key words

Patella Patellofemoral syndrome Computerized tomography 

Résumé

Cinquante et un genoux présentant une symptomatologie fémoro-patellaire, mais dont les radiographies standard étaient normales, ont bénéficié d'un examen par tomodensitométrie. Tous, sauf cinq, montraient une désaxation évidente et présentaient, lors de l'intervention, des altérations cartilagineuses. Les auteurs concluent que dans de nombreux cas la tomodensitométrie est le meilleur moyen de diagnostic en cas d'atteinte de l'articulation fémoro-patellaire.
