Abstract

L'invention concerne un implant d'articulation fémoro-patellaire (100) et une méthode correspondante pour son implantation. Dans certains modes de réalisation, l'implant d'articulation fémoro-patellaire est agencé et configuré pour être positionné (p. ex., reçu, inséré, etc.) dans une poche formée dans le fémur du patient. En outre, et/ou en variante, l'implant d'articulation fémoro-patellaire est disposé et configuré pour être implanté sans nécessiter de ciment (p. ex., application non cimentée). Ainsi agencé, l'implant d'articulation fémoro-patellaire peut être désigné comme un implant d'articulation fémoro-patellaire inséré non cimenté. Dans certains modes de réalisation, la poche peut être formée par un système chirurgical robotique orthopédique et l'implant d'articulation fémoro-patellaire peut être accouplé dans la poche par un ajustement serré entre l'implant d'articulation fémoro-patellaire et les parois de la poche.
