title: Total hip joint replacement using a CoCrMo metal-metal sliding pairing.
abstract: Late loosening in total hip replacement is explained by a foreign body reaction of the connective tissue along the bone-implant interface due to polyethylene debris. In contrast, metal-metal prostheses of the McKee type implanted in the sixties, may still work perfectly today without any signs of osteolysis along the bone-cement interface, proving that metal-metal pairing is superior to prostheses with polyethylene cups and proving also that cement anchorage may be adequate for fixation. A new metal-metal total hip joint is presented, that has been implanted 90 times between 1988 and 1991.
