An implant (40) for installation into a portion of an articular surface (50) includes a protrusion (45) configured to cover and un-excised portion of articular surface proximate to the implant (40). Another implant may form a cavity to allow the un-excised portion of articular surface to remodel over a perimeter edge of the implant. The implant (40) may also includes indentations (6805) such as grooves (6807) to promote articular cartilage remodeling over a portion of the load bearing surface of the implant (40). An elongated or non- round implant (6600) is also provided having two opposing concentric arcuate shaped sides (6611, 6612), as well as a method to seat such an implant in an articular surface. A method for seating an implant without cutting articular cartilage is also provided.
La présente invention concerne un implant venant s'installer dans une partie d'une surface articulaire. Cet implant qui forme une surépaisseur, vient de par sa forme recouvrir une partie non excisée d'une surface articulaire à proximité de l'implant. L'invention concerne également un autre implant dégageant une forme creuse laissant la partie non excisée de la surface articulaire reconstituer une continuité des formes au-delà du pourtour de l'implant. L'implant peut également comporter des indentations, notamment des rainures, pour favoriser le remodelage du cartilage articulaire sur la partie de la surface de l'implant supportant les charges. L'invention concerne aussi un implant oblong ou non rond à deux côtés concentriques arqués et le procédé de mise en place d'un tel implant dans une surface articulaire. L'invention concerne enfin un procédé permettant la mise en place d'un implant sans découpe du cartilage articulaire.
