    摘要: A combination of a first assembly for guiding resection of a femur and tibia of a knee joint and a second assembly including femoral and tibial knee components. The combination of the first assembly and the second assembly provides optimal placement and positioning of the femoral and tibial knee components to achieve near-normal knee kinematics and tension. The preparation for and placement of the prosthetic knee components provides medial-pivoting kinematics mimicking that of the natural knee thereby promoting improved outcome for the patient.

    摘要: An assembly for guiding resection of a femur and tibia of a knee joint in preparation for installing a femoral and tibial knee components. For example, the assembly can include tibial and femoral IM rods to which are connected through a tensioning bolt that allows controlled adjustment of the distraction of the tibia and femur during cut positioning in a range of flexion angles. Also, the assembly is usable with relatively small, noninvasive approaches to the knee joint by way of relatively narrow, low profile components that attach to tibial and femoral IM rods. Further, the assembly includes several quick-release components to allow fast assembly and disassembly in a surgical setting. Each of these aspects, along with the ability of the assembly to accurately guide initial reference cuts to the tibia and femur, promotes an improved outcome for the patient.

    摘要: A system for use in a total knee arthroplasty procedure can include a first cutting guide, an alignment guide and a femoral prosthetic implant. The first cutting guide can include at least one planar guide surface adapted to guide a cutting tool to cut femur. The alignment guide can contact the femur and provide for markings to be made in the femur that dictate a location and orientation of the first cutting guide. The implant is adapted to be implanted on the resected femur. The implant can have an inwardly protruding structure to provide medial-lateral fixation stability, and can have an anterior fixation path that diverges proximally away from a long axis of the femur and a posterior fixation path that converges proximally towards the long axis such that the posterior fixation path and anterior fixation path converge toward one another proximally of a distal contact surface.

    摘要: A method for making a surgical cutting guide and the guide made by this method. The method includes obtaining a number of cross sectional images of a patient joint taken at a defined interval. On each image a patient contour is imaged. These patient surface contours are used to generate a pattern of parallel ridges on a surgical cutting guide.
