Knee replacement surgery. Prosthetic knee implants ready for use in total knee replacement surgery. During the operation prostheses will be implanted into the thigh bone (femur) and shinbone (tibia) to form an artificial knee joint. These devices are tibial spacers, which go between the two prostheses. Knee joints need replacing when the protective cartilage that surrounds them is lost.
