摘要： A computer-implemented method determines an orientation parameter value of a prosthetic component. The method includes receiving a first desired separation distance between a tibial prosthetic component and a femoral prosthetic component at a first flexion position of a knee joint and estimating a first estimated separation distance between the tibial prosthetic component and the femoral prosthetic component at the first flexion position of the knee joint for at least one potential orientation of the femoral prosthetic component. The method also includes determining a first orientation parameter value of the femoral prosthetic component by comparing the first estimated separation distance to the first desired separation distance and outputting the first orientation parameter value via a user interface.

摘要： A tibial prosthesis comprises a medial base portion configured to engage a medial surface of a tibia and a lateral base portion configured to engage a lateral surface of the tibia. At least a portion of the medial and lateral base portions are separated by a passage interposed therebetween. The tibial prosthesis also comprises a bridge coupling the medial base portion and the lateral base portion, wherein at least a portion of the bridge is elevated above a portion of the passage between the medial base portion and the lateral base portion. The bridge may define an underlying area that receives at least a portion of a tibial eminence when the tibial prosthesis is engaged with the tibia, wherein the height of the bridge varies in a superior direction across the passage.

摘要： A prosthetic device for a knee joint includes a body portion and a first keel. The body portion attaches to a bone of a knee joint. The body portion can have a bearing surface configured to replace at least a portion of the bone and an implantation surface configured to face the bone upon implantation. The first keel can be configured to be inserted into a corresponding first keel void formed in the bone. The first feel can be configured to project outwardly from the implantation surface by an amount sufficient to inhibit movement of the body portion relative to the bone in both medial and lateral directions upon insertion into the first keel void. The first keel can extend along a longitudinal direction of the body portion and is offset from a longitudinal centerline of the body portion. Methods of implanting and removing the prosthetic device are also provided.

摘要： A prosthetic device for forming at least a portion of a joint may have a plurality of segmented components fixed relative to a femur of a body including: a patellofemoral component and a condyle component. Each segmented component may be configured such that a placement at which the segmented component will be fixed relative to the femur is not constrained by a connection to another of the segmented components that is fixed relative to the femur. In an installed configuration, the patellofemoral and condyle components may be fixed relative to the femur such that: a gap is provided between an edge of the patellofemoral component and an opposing edge of the condyle component, and a transition region is provided that extends from a first femoral coronal plane that intersects the patellofemoral component to a second femoral coronal plane that intersects the condyle component.
