Abstract
An implant to replace a rear patella part is provided, which comprises a prosthesis part imitating the patella part and a metal attachment part fixed in the prosthesis part, with which the implant can be attached in the natural patella part. In order to produce a gentle and secure attachment for the implant, the attachment part has a convexly curved external contour, which at least in sections has an open-cell and open-pore surface structure.
