The lower
end of the thigh bone (femur) is resurfaced with a metal cap.
The upper end of the leg bone (tibia) is replaced
with a plastic and metal implant with cement and or screws.
The back of the kneecap (patella) is also resurfaced with an all-plastic
implant. Highly specialized instruments are used that allow precision
cutting of the bone so that the new joint fits perfectly. The type
of implant used depends on surgeon's preference and patient requirements.)
