  • Patent number: 11903836
    Abstract: A femoral component for a prosthesis used in a total knee arthroplasty includes a posterolateral taper on the lateral condyle. The lateral and medial condyles of the femoral component are asymmetric to accommodate for the asymmetry of a resected lateral and medial condyle of a femur. The taper is designed to improve the fit of femoral component on the femur to eliminate or reduce overhang of the femoral component's lateral condyle, thereby reducing pain, irritation, stiffness, soreness, or any other symptoms of an improperly fitting prosthesis.

  • Patent number: 9820855
    Abstract: The present invention provides a femoral prosthesis for a femur which can enable or allow deep knee flexion without creating excessive tension in the ligamentous structure of the knee. The femoral prosthesis includes an internal non-articulating surface, an external articulating surface, a medial condyle and a lateral condyle. The height of the medial condyle is less than the height of the lateral condyle. A proximal-posterior tip of the medial condyle is rounded and is shifted inwards relative to the native level of the proximal-posterior region of the femur bone to facilitate knee flexion. A method of mounting a femoral prosthesis on a femur is also described.

  • Patent number: 9808348
    Abstract: Implants, and processes for installing them, which replace the medial condyle and portions of the patellofemoral channel but preferably not portions of the lateral condyle that articulate relative to the tibia. Processes are provided which allow proper location and orientation of an anterior resection and a distal resection on the femur, which make use of a transition point which can be designated on the bone, for navigating proper positioning of such implants. Proper positioning of the implant relative to the femur for insuring a smooth transition between lateral portions of the implant and the lateral condyle is thus reduced to determining proper medial/lateral location of the implant on the anterior and distal resections.

  • Patent number: 9763791
    Abstract: A prosthetic head for a femoral component has a metal shell with a tapered cavity. The shell has a part-spherical outer surface defining an inner portion terminating in an open end. A polymeric material completely fills the inner portion of the hollow shell extending from an inner surface of the shell to the open end. The polymeric material includes a conically tapered socket centered about the polar axis intermediate ends of the open end wherein the shell is a hollow titanium shell having an inner surface with a porous structure for receiving a portion of the polymeric material. The hollow titanium shell inner surface has at least one rib extending inwardly toward the conically tapered socket.

  • Patent number: 9675441
    Abstract: A bearing component 2 for a joint replacement prosthesis comprises a first bearing element 4; a second bearing element 6, and a linking element 8, operatively connecting the first and second bearing elements 4, 6 and permitting relative motion there between. The flexible linking element 8 prevents dislocation of mobile bearings in a total knee replacement prosthesis. The invention also relates to a bridging element which retains the linking element 8 with some play, which acts as a ligament support 2051, and which causes a deflection of the line of action of a ligament 1018. A joint replacement prosthesis is also disclosed comprising a biasing element 1140 or a tensioning element 1220 operatively coupled to the artificial ligament 1018. The biasing element 1140 or tensioning element 1220 may be housed in the stem of a tibia tray 1006.

  • Patent number: 9522066
    Abstract: The present invention provides for a variety of fracture fixation options should a fracture occur after total hip arthroplasty or total knee arthroplasty, and provides associated methods and apparatus for application of provided fixation. The ability to pre-engineer fracture fixation contingent solutions into femoral or tibial components provides for a distinct clinical advantage in the planning and execution for periprosthetic fracture fixation. Said methods and apparatus include targeting devices which allow for intimate association of fixed angle locking screws in pre-drilled holes in an existing prosthetic, femoral nail, or other components including additional fixation components. Use of pre-engineered fracture fixation contingent solutions into femoral or tibial components provides for a distinct clinical advantage in the planning and execution for periprosthetic fracture fixation.

  • Patent number: 9427336
    Abstract: A dynamic trialing method generally allows a surgeon to perform a preliminary bone resection on the distal femur according to a curved or planar resection profile. With the curved resection profile, the distal-posterior femoral condyles may act as a femoral trial component after the preliminary bone resection. This may eliminate the need for a separate femoral trial component, reducing the cost and complexity of surgery. With the planar resection profile, shims or skid-like inserts that correlate to the distal-posterior condyles of the final insert may be attached to the distal femur after the preliminary bone resection to facilitate intraoperative trialing. The method and related components may also provide the ability of a surgeon to perform iterative intraoperative kinematic analysis and gap balancing, providing the surgeon the ability to perform necessary ligament and/or other soft tissue releases and fine tune the final implant positions based on data acquired during the surgery.

  • Patent number: 9398958
    Abstract: Tibial inserts and tibial femoral systems are provided for improved knee reconstruction systems. External rotation of a knee joint implant is enhanced by modifications to the post, providing a recess that allows clearance of the post against the corners of a box wall within the femoral component. The rotation provides for a more natural knee joint motion of the implant. The depth, size, and location of the post relief may be modified for certain applications to provide both improved rotational motion and constraint against undesirable motion of the knee.
