A process of orthopedic implantation of prosthetic devices such as hip and knee joints. The prepared bed of the bone cavity is lined with a pre-coating mixture of bone cement and resorbable particles, followed by filling of the bed with substantially pure bone cement and thereafter the prosthesis is positioned into the fully prepared bed. In this manner, resorbable particles along the lined prepared bed wall are resorbed by the patients body and replaced with new bone tissue ingrowth. As a result bonding of the bone cement to the bone is substantially improved, without weakening the bonding of the implant to the bone cement.
