摘要： A method and apparatus for correcting limb alignment in a unicondylar knee arthroplasty and linking the distal femoral cut and the proximal tibial cut. Alignment rods are connected to a spacing apparatus to facilitate correction of limb alignment. The alignment rods are positioned along the mechanical axis of the femur and the tibia and the knee joint is positioned to correct alignment. A spacing apparatus is positioned in the relevant knee compartment and utilized to hold the knee in position to correct limb alignment. The spacing apparatus includes a femoral cut slot through which the distal femoral cut is made and further includes tibial affixment apertures through which a headless securing device can be positioned to secure the spacing apparatus to the tibia. After the distal femoral resection is complete, the spacing apparatus is removed, with the headless securing devices remaining positioned in the tibia. The headless securing devices are used as a reference for securing a tibial cut block to the tibia for making the proximal tibial resection. With the mechanism of the present invention, the knee can be placed in flexion when making the proximal tibial cut and the distal femoral cut is linked to the proximal tibial cut.

摘要： A mobile bearing unicondylar tibial knee prosthesis includes a tibial base plate and a tibial articular surface component. The inferior surface of the articular surface component engages the superior surface of the base plate in sliding relationship. The tibial articular surface and a stop on the tibial base plate define a tab and groove engagement between them such that the tibial articular surface component is permitted to slide anteriorly-posteriorly on the tibial base plate while movement of the tibial articular surface component superiorly away from the base plate is restricted.

摘要： The present invention relates to a bone-cutting guide used during arthroplasty. The bone-cutting guide is intended to be temporarily positioned against the distal femur or proximal tibia bone surface and to receive a cutting member. The bone-cutting guide is intended to cut the bone generally transverse to the length of the bone, and includes a main body and a paddle. The main body has a width defined between first and second surfaces. A cutting tool receiving portion, which is configured and arranged to receive the cutting member, extends from the first surface to the second surface. The main body is configured to be placed against a side surface of the bone. The paddle extends from the main body and includes a bone-contacting surface that is configured and arranged to be positioned generally parallel against the distal femur or the proximal tibia bone surface.
