    Abstract: A joint prosthesis includes e.g., a femoral component and a tibial component. The medial and lateral condylar articular surfaces may have substantially uniform and equal radii from full extension to about 90° of flexion. From 90°, the lateral condylar articular surface has a smaller radius than the medial condylar articular surface such that the medial condyle gradually becomes increasingly more proud than the lateral condyle to facilitate internal rotation of the tibia at deep flexion. Also, the tibial articular component may include a post intermediate the medial and lateral compartments that engages a cam on the femoral articular component between the medial and the lateral condylar articular surfaces. The cam and post become congruent at flexion angles of approximately 70° flexion and mate symmetrically during the first 20°-30° of further flexion, and then mate asymmetrically at greater degrees of flexion to force internal rotation of the tibia.

    Abstract: An implantable orthopaedic knee prosthesis includes a femoral component including an articular surface configured to engage a tibial bearing and a laterally-angled trochlear groove defined in the articular surface. The trochlear groove of the femoral component is configured to receive a patella component in a first location at a first degree of flexion and a second location at a second degree of flexion. The second degree of flexion is greater than the first degree of flexion. An arced imaginary line defines a central section of the trochlear groove. When the femoral component is viewed in a first coronal plane extending through the first location, the arced imaginary line has a first radius of curvature. When the femoral component is viewed in a second coronal plane extending through the second location, the arced imaginary line has a second radius of curvature that is less than the first radius of curvature.

  • Patent number: 8721732
    Abstract: Systems and methods for providing deeper knee flexion capabilities. In some instances, such systems and methods include an asymmetrical femoral component that includes a femoral prosthesis that is configured to attach to a distal portion of a femur. In some such instances, the prosthesis includes a medial condyle and a lateral condyle, wherein a medial-lateral width of an articulation surface of the lateral condyle is approximately 75% or less of a medial-lateral width of an articulation surface of the medial condyle. Other implementations are also discussed.

  • Patent number: 8715361
    Abstract: Systems and methods for providing deeper knee flexion capabilities. In some instances, such systems and methods include a knee prosthesis that includes a femoral component for replacing at least a portion of a distal end of a femur. In some cases, the femoral component has a posterior condyle that is configured to articulate against a tibial articular surface. In such cases, an articular surface at a proximal portion of the posterior condyle is sized and shaped to extend at least half of an antero-posterior distance between a most posterior portion of the posterior condyle and a plane that is a continuation of a distal one fourth to one third of a posterior cortex of a femoral shaft of the femur. Other implementations are also discussed.

  • Patent number: 8715358
    Abstract: A new class of total knee replacement includes a posterior cruciate ligament retaining anterior cruciate ligament substituting apparatus and method. Particular design considerations include: 1) a specific extension surface separate from the flexion surface, 2) rotational control in full extension to create the so-called screw-home mechanism, 3) translation restraints that will substitute for ACL function including a CAM-post or other abutment mechanism while allowing normal PCL function which should improve natural proprioception, 4) a modified femoral component with separate radii of curvature for the flexion and extension arcs of at least one condyle, and 5) a tibial component with slope built into the posterior aspect of its bone contacting surface on both sides of the PCL.

  • Patent number: 8709090
    Abstract: A system for manipulating energy transferred by members defining a joint. The system includes a first attachment structure configured to be attached to a first member of the joint and a second attachment structure configured to be attached to a second member of the joint. There is also an adjustable energy absorbing device attached to the first attachment structure and second attachment structure, wherein adjusting the energy absorbing device changes the load manipulating characteristics of the energy absorbing device.

  • Patent number: 8702802
    Abstract: A joint assembly incorporated into a reconditioned end surface established between upper and opposing lower bones. At least one first component is anchored into a first of the reconditioned bone end surfaces and exhibits a rotatably supported wheel. A second component is anchored into a second opposing reconditioned bone end surfaces and exhibits a second exposed support surface in contact with the rotatably supported wheel. The first component includes a supporting well anchored into the reconditioned bone end surface for supporting the wheel in rotatable fashion. A laterally inserting pin displaces relative to a side of the wheel well and into an interior thereof and includes a central axial through hole which receives the pin for supporting the shaft.

  • Publication number: 20130317621
    Abstract: A prosthetic knee joint assembly includes a femoral component and a bearing that supports articulation of the femoral component. The assembly further includes a tibial tray. Furthermore, the assembly includes a ligament link operably coupled to the tibial tray or the femoral component via a coupling component. The ligament link extending through the other of the tibial tray or the femoral component to couple to the respective one of the femur or tibia. The ligament link extends between first and second ends and includes an outer wall defining an interior longitudinal passage portion. First and second apertures extend through the wall. The first end extends through the first and second apertures and the longitudinal passage portion to define a first adjustable loop, and the second end extends through the first and second apertures and the longitudinal passage portion to define a second adjustable loop.

  • Patent number: 8591594
    Abstract: An orthopaedic tibial prosthesis includes a tibial baseplate sized and shaped to cover substantially all of a resected proximal tibial surface, and a tibial bearing component sized to leave a posteromedial portion of the tibial baseplate exposed when the tibial bearing component is mounted to the baseplate. The exposed posteromedial portion of the tibial baseplate includes a chamfered profile which cooperates with a correspondingly chamfered profile at a posteromedial edge of the tibial bearing component to create a substantially continuous chamfer extending from the resected tibial surface to the medial articular surface of the tibial bearing component. Advantageously, this chamfer leaves an absence of material (i.e., a relief or void) at the posteromedial edge of the tibial prosthesis, thereby enabling deep flexion of the prosthesis without impingement between the tibial prosthesis and adjacent anatomic tissues or prosthetic structures.
