摘要： An instrument system for setting the internal-external rotation of a prosthetic femoral component with respect to a proximal tibia has a bone resection instrument having a planar surface for engaging a planar surface of a resected distal femur. The bone resection instrument system has a cutting guide for guiding a tool for resecting a posterior surface of the distal femur and forming a cylindrical surface on the posterior condyle intersecting the planar surface. The cylindrical surface defined by an axis extending in a direction generally perpendicular to the resected planar surface. The system includes a trial component having a planar surface for engaging the planar surface of the resected distal femur and having posterior condyles having a cylindrical anteriorly facing surface engagable with the resected cylindrical surface on the posterior condyle.

摘要： A method for setting the internal-external rotational position of a prosthetic femoral component with respect to the tibial comprises: forming a cylindrical surface on the posterior femoral condyles. The cylindrical surface is formed about an axis extending in a proximal distal direction with respect to the femur. A template is placed on the distal femur which has a cylindrical guide surface for engaging the posterior femoral condyles. When placed against a planar resected surface of the distal femur the guide surfaces contact the cylindrically shaped posterior condyles. The template is rotated on the cylindrical guide surface as the knee joint is moved from flexion to extension until the template cylindrical guide surfaces are in a position with respect to the tibial condyle surfaces to properly balance the knee ligaments.

摘要： A cutting block having a base, and a top connected to the base via four walls is disclosed. Each wall has an outwardly facing surface to guide a cutting tool. Each wall also has an attachment hole where a tracker may be attached. The cutting block is floated on the bone using the navigation system to position it at correct locations for the bone resection. After correctly locating the cutting block for each required cut, cutting block is fixed to the bone using pins and the bone resected. Same cutting block is suitable for resection of bone for installation of any size prosthetic device. For certain resections, the rotation angle may be mechanically set and need not be navigated.

摘要： A knee prosthesis and method for emulating movements, during flexion, of a natural knee joint replaced by the knee prosthesis, by enabling engagement and relative movement between the femoral component and the tibial component of the knee prosthesis along arcuate tracks, including rotational movement about a longitudinal axis of rotation, during flexion about a transverse axis of rotation, and maintaining the transverse axis of rotation essentially in a generally medial-lateral longitudinal plane maintained in close proximity with a generally coronal plane passing through the centers of curvature of the arcuate tracks during flexion within at least a prescribed range of flexion extending from about 0° of flexion to a predetermined degree of flexion, preferably about 60° of flexion. A stabilizing mechanism couples the femoral component with the tibial component within a portion of the prescribed range of flexion, the portion being between about 45° of flexion and about 60° of flexion, for providing stability and for assisting in maintaining the transverse axis of rotation essentially in the longitudinal plane, and the longitudinal plane in close proximity with the coronal plane as the longitudinal plane is rotated about the longitudinal axis of rotation.

摘要： An apparatus and method for tibial alignment which allows the independent establishment of two separate geometric planes to be used as a reference for the cutting of the tibial plateau during total knee arthroplasty. Two separate frame assemblies with telescoping rods are attached to the tibia with a fixed relative angle between them, thereby allowing alignment with the mechanical axis of the bone. A cutting block is mounted on one of the assembly frames and is positioned against the tibia. Stabilizing pins are then placed in the cutting block, allowing the proper tibial plateau resection plane to be created.

摘要： A method and apparatus for preparing a planar surface on the distal femur prior to implantation of a femoral knee prosthesis has a femoral plate with an opening therein for exposing both condyles of the femur. A guide with a central aperture is used to align the femoral plate on the distal femur. The guide is releasably secured to the femoral plate and an intramedullary guide rod is placed through the aperture therein and into the intramedullary canal of the femur. After alignment with the intramedullary canal, the femoral plate is pinned to the femur and the rod and guide are removed. A milling guide having two bores, one adjacent each condyle, is then placed on the femoral plate and an end mill is used to mill a planar surface on at least one of the condyles.
