    摘要: A set of instruments for preparing a femur and tibia for receipt of a partial knee prosthesis can include a femoral drill guide that is selectively connected to an intramedullary (IM) rod. At least one sizing spoon can communicate with the femoral drill guide. The femoral drill guide can have terminal cutting surfaces. A tibial cut guide can be selectively connected to the femoral drill guide. A dial member can be disposed on one of the femoral or tibial cut guides that when rotated moves at least one of the spoons in a superior/inferior direction.

    摘要: A modular knee prosthesis can include a femoral component having a superiorly extending portion, a first femoral bearing surface and a second femoral bearing surface. The superiorly extending portion can define a first tapered augment receiving surface. A tibial component can have an inferiorly extending portion and a tibial bearing surface. The inferiorly extending portion can define a second tapered augment receiving surface. A first augment can define a first receiving bore and a first stepped surface. A second augment can define a second receiving bore and a second stepped surface. The first and second augments are adapted to mate at the first and second stepped surfaces in a first position at the first tapered augment receiving surface of the femoral component and in a second position at the second tapered augment receiving surface of the tibial component.

    摘要: A method for preparing at least a first bone for receiving a prosthesis can include positioning an IM member in a bone. A scaffold, skeleton or frame can be located onto the bone at a desired location. An alignment assembly can be coupled to the frame. The alignment assembly can be moved relative to the IM member to position the frame at a desired location relative to the bone. The frame can be fixed to the bone at the desired location. A cavity can be reamed into the bone using at least a portion of the alignment assembly as a guide. The alignment assembly can be removed from the frame. A cutting block can be coupled to the first attachment portion. Cuts can be prepared in the bone using the cutting block as a guide.

    摘要: A method of positioning a femoral cutting guide on a distal end of a femur establishes at least a first reference plane to perform a distal femoral planar cut. The method includes inserting a mounting member into an intramedullary canal of the femur and coupling a bridge member to the mounting member. The method also includes placing a cutting guide member over a medial anterior portion of the distal femur. The cutting guide member has a first channel that establishes the first reference plane. The bridge member has a bridge channel. A wall of the bridge channel is inserted into the first channel of the cutting guide member. A mounting mechanism generates resistance between the bridge member and the cutting guide member. The resistance is overcome by positioning the cutting guide member relative to the femur.

    摘要: A system for cooperating with an elongated IM member during preparation of a bone for receiving a prosthesis can include a scaffold, skeleton or frame. An alignment assembly can be selectively coupled to the frame. The alignment assembly can cooperate with the IM member to position the frame relative to the bone. A cutting block can be selectively coupled to the frame. According to other features, a posterior stabilized (PS) box guide assembly can have a PS box guide attachment portion that selectively couples with the first attachment portion of the frame. A posterior foot can selectively couple with a second attachment portion on the frame. The posterior foot can be positioned to occupy space of a joint line in an installed position.
