Abstract

The present invention relates to a prosthetic implant for the replacement of hard tissues of bones or joints that provides improved initial fixation to the bone or joint substrate. A t least a part of the outside of said implant is composed of a biocompatible construct, wherein at least a part of the exterior of the construct that is used to attach the implant to bone or joint consists of a curved or planar surface carrying a plurality of protruding parts each characterized by a height of 10 - 1000 ¼m and a maximum diameter of 10 - 1000 ¼m, said protruding parts being characterised in that they are sufficiently sharp to penetrate bone; and wherein the surface of the construct that is used to attach the implant to bone or joint has a total in - plane projection area of at least 1 cm 2 and contains at least 50 of the aforementioned protruding parts per cm 2.
