<p>A guide for use in determining the location of a plane for resecting one of the femoral condyles in a knee joint, relative to a reference surface on the tibia, to prepare the condyle for implantation of the femoral component of a unicompartmental knee joint prosthesis. The guide comprises a first limb which can be inserted between the femur and the tibia, in contact with the reference surface on the tibia, the first limb having a femoral surface which faces towards the femur and a tibial surface which faces towards the tibia. A second limb extends generally perpendicularly from the first limb so as to extend over the femur when the first limb is inserted between the femur and the tibia, which has at least two holes formed in it to locate fixation holes on the femur. The first limb is configured to fit between the reference surface of the tibia and the respective condyle. The tibial surface of the first limb has at least two generally flat portions when the limb is viewed in cross-section looking along its length so that the tibial surface is generally convex, the included angle defined by the flat portions being at least about 165°.</p> |
