  • 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: 8974538
    Abstract: A temporary knee replacement assembly and kit includes a tibial plate that attaches to the tibia, a tibial rod that extends through the plate into the medullary cavity and abuts the plate. A femoral plate attaches to the femur, and a femoral rod extends through the second plate into the femur medullary cavity and abuts the plate. A locking spacer connects the two rods. The spacer may be length adjustable or may be provided in multiple sizes for length selection. One or both of the rods may include a bone cement/antibiotic coating to provide antibiotic treatment to the tissue. The kit may include multiple tibial and femoral rods, multiple tibial and femoral plates, and multiple locking spacers, to accommodate different applications.

  • Patent number: 8936648
    Abstract: A prosthesis for replacing a knee joint between a femur and a tibia can include a femoral component, a tibial component, a bearing and a yoke assembly. The yoke assembly can have a yoke disposed between the bearing and the femoral component and an axle having an axle axis. The axle can hingedly couple the yoke with the femoral component. Rotation of the femoral component about a rotation axis that is perpendicular to the axle axis causes concurrent rotation of the yoke about the rotation axis.

  • Patent number: 8932363
    Abstract: The present invention relates to methods for determining meniscal size and shape for use in designing therapies for the treatment of various joint diseases. The invention uses an image of a joint that is processed for analysis. Analysis can include, for example, generating a thickness map, a cartilage curve, or a point cloud. This information is used to determine the extent of the cartilage defect or damage and to design an appropriate therapy, including, for example, an implant. Adjustments to the designed therapy are made to account for the materials used.

  • Patent number: 8911502
    Abstract: Embodiments of the invention provide knee prostheses which more faithfully and closely replicate the function, anatomy and physiology of the normal human knee yielding a number of advantages. Among other things, such prostheses can provide an increased range of motion and function more normally particularly in extension, deep flexion and during normal gait. Knee prostheses according to various aspects of the invention recognize that during movement of the knee, particularly during flexion, the kinematics of the bones of the knee are a result of achieving equilibrium of the forces that cause motion of the knee. In addition, the shape of the articular surfaces acting in combination with forces imposed by various muscles, ligaments and tendons, determines the direction of the large contact forces.
