Abstract 

In 78 patients undergoing a total hip replacement we examined the production of matrix metalloproteinases (MMP) by the fibroblasts from the connective tissue of the acetabulum; we then correlated these findings with clinical and radiological characteristics of the same patients. In 53 patients only MMP-2 was produced; in 15 cases MMP-1, -2 and -3 were present; and in 10 cases not only MMP-1, -2, -3 but also MMP-9. Significant differences among the clinical and radiological parameters were found in the 3 subsets. A positive correlation between the production of MMP-9 and a rapid destruction of the hip joint was found.

Résumé

 Nous avons examiné la production de métalloprotéinases (MMP) par des fibroblastes dans 78 patients souffrant d’une ostéo-arthrite de la hanche. La production de MMP fut classée en 3 sous-sembles: 53 patients dans lequel seulement des MMP-2 furent détectées; 15 patients dans lequels des MMP-1, -2 et –3 étaient présentes; et 10 patients où des MMP-1, -2, -3 et aussi des MMP-9 furent détectées. Des différences importantes furent découvertes pour des paramètres cliniques et radiologiques parmi les sous-sembles. Il y’a une correlation positive entre la production de MMP-9 et une destruction rapide de la hanche.
