摘要： A surgical saw blade guide or milling instrument guide comprising a guide body having a guiding surface thereon, and containing a magnet therein which exerts attractive force in a direction toward the guide body for attracting a bone saw blade or milling instrument to the guiding surface. The surgical saw blade guide or milling instrument guide can comprise a plurality of magnets and the magnet or magnets can themselves form part of the guiding surface. Also, a method of cutting a bone comprising the steps of magnetically attracting a surgical bone saw blade or milling instrument to a surgical saw blade guide or milling instrument guide containing a magnet, actuating a bone saw coupled to the bone saw blade or actuating a milling instrument, advancing the bone saw blade or milling instrument into the bone thereby cutting the bone, and detaching the saw blade or milling instrument from the guide.

摘要： A knee prosthesis for use in a total knee replacement surgical procedure may include a femoral component, a tibial component and a meniscal component. Optionally, the prosthesis may also include a patellar component. The femoral component may include a bone attachment side and a joint facing side, the latter including an anterior joint surface, a posterior joint surface having a cross-sectional shape defining a portion of a cylinder, and medial and lateral grooves between the anterior and posterior joint surfaces. The meniscal component may include a number of features designed to mate with the femoral component to provide relatively natural movement and range of motion about the knee joint as well as stability and resistance to wear and tear.
