An orthopaedic prosthesis including a tibial tray is disclosed. The tibial tray includes a distal pocket and a plurality of inner pockets. Each inner pocket includes a channel sized to receive bone cement. The tibial tray includes distal-facing surfaces that have a surface roughness (Ra) equal to about 5.0 microns.

Tibial tray with fixation features

An orthopaedic knee prosthesis includes a tibial insert and a femoral component configured to articulate on the tibial insert. The tibial insert includes a lateral articular surface and medial articular surface that is asymmetrically shaped relative to the lateral articular surface. The medial articular surface is shaped to reduce anterior translation of a medial condyle of the femoral component, while the lateral articular surface is shaped to allow a lateral condyle of the femoral component to pivot, relative to the medial articular surface, along an arcuate articular path. Additionally, one or both condyles of the femoral component may include a femoral articular surface having a curved femoral surface section defined by a continuously decreasing radius of curvature.

Medial stabilized orthopaedic tibial insert

Methods and apparatus for planning and/or carrying out a total knee replacement surgical procedure on a knee of a leg of a patient are described. Anatomical data for the leg of the patient is obtained, which allows the femoral mechanical axis, the tibial mechanical axis, and the joint line of the knee to be determined. A planned proximal tibial cut angle and a planned distal femoral cut angle are determined. A total knee replacement procedure is carried out on the knee of the patient such that a distal femoral cut is made using the planned distal femoral cut angle and a proximal tibial cut is made using the planned proximal tibial cut angle.

Surgical planning and method

A total knee implant prosthesis is disclosed. The total knee implant prosthesis includes a tibial component including a pair of bearing surfaces and a post positioned between the bearing surfaces, and a femoral component configured to rotate relative to the tibial component. The femoral component includes a pair of condyles sized and shaped to articulate on the bearing surfaces and a cam positioned between the pair of condyles. The cam engages the post at a first contact point when the femoral component is at 0 degrees of flexion and engages the post at a second contact point located lateral of the first contact point when the femoral component is at a first degree of flexion greater than 0 degrees. The cam is disengaged from the post when the femoral component is at a second degree of flexion greater than the first degree of flexion.

Total knee implant prosthesis assembly and method

An orthopaedic prosthesis system and associated instrumentation is disclosed. The system includes femoral and tibial components configured to be used in a number of different implanted configurations. The instrumentation is configured to facilitate preparation of the bones and selection of the implant configuration. A method of using the system is also disclosed.

Orthopaedic knee prosthesis system and methods for using same

Medial stabilized orthopaedic knee prosthesis

An orthopaedic knee prosthesis includes a femoral component having a condyle surface. The condyle surface is defined by one or more radii of curvatures, which are controlled to reduce or delay the onset of anterior translation of the femoral component relative to a tibial bearing.

Orthopaedic knee prosthesis having controlled condylar curvature

Methods and apparatus for planning and/or carrying out a total knee replacement surgical procedure on a knee of a leg of a patient are described. Anatomical data for the leg of the patient is obtained, which allows the femoral mechanical axis, the tibial mechanical axis and the joint line of the knee to be determined. A planned proximal tibial cut angle and a planned distal femoral cut angle are determined. A total knee replacement procedure is carried out on the knee of the patient, wherein a distal femoral cut is made using the planned distal femoral cut angle and a proximal tibial cut is made using the planned proximal tibial cut angle.

An orthopaedic surgical system for a total knee implant includes a plurality of commonly-sized femoral trial components. Each commonly-sized femoral trial component includes a first femoral condyle having a first articulation surface configured to engage a tibial component, and a second femoral condyle may be spaced apart from the first femoral condyle. The second femoral condyle has a second articulation surface configured to engage the tibial component. An anterior cam is positioned between the first femoral condyle and the second femoral condyle. A method of using such a system is also disclosed.
