摘要：
The invention relates to a rotary mill and guide for use in preparing a bone for total or partial joint replacement surgery. The mill comprises a body portion 4 with a milling surface 10, and a central bore 20 extending along an axis of rotation 18 of the body portion 4. The guide comprises a guide portion 6 with a guide body 22 and a guide peg 24 extending from the guide body 22 which is received in the central bore (20 figure 3) of the body portion 4. The guide body 22 has at least one alignment feature 28, 30 which is the same as that of a prosthesis component. A later embodiment relates to a method of implanting a unicondylar femoral component comprising the steps of, a) reaming the femoral condylar surface to accept the unicondylar femoral component b) drilling peg holes for affixing the unicondylar femoral component c) affixing a guide portion of a rotary mill onto the prepared condylar surface using the drilled peg holes d) reaming a portion of bone anterior to the affixed guide portion e) removing the guide portion from the bone and f) affixing a unicondylar femoral component to the prepared condylar surface.
