  • Patent number: 11324518
    Abstract: A method of attaching prosthetic implants to bone, applicable to tibia, patella, acetabulum, glenoid, or femur, includes trimming an articular surface of the bone, leaving a trimmed surface. Holes are punched or drilled into the surface in a predetermined array before polymethyl methacrylate bone cement is used to attach the surface to the implant. In an embodiment, the holes are punched by placing a punch-plate with sharpened punch spikes on the surface, and striking the punch plate to drive punches into the trimmed surface. In another embodiment, holes are drilled using a drilling template with predrilled guidance holes placed on the surface of the bone. In another embodiment, holes are drilled by positioning a robotic drill over the trimmed surface; adjusting a drilling pattern of the robotic drill according to the trimmed surface; and using the robotic drill to drill holes of predetermined depth according to the drilling pattern.
