    Abstract: The invention relates to a prosthesis for implantation into a long bone during joint arthroplasty and a method for use. An exemplary long bone implant comprises a first end, a second blunt tip end, and a stem of the implant disposed there between, such that a proximal portion of the stem comprises an anterior surface, a posterior surface, a medial surface and a lateral surface, wherein a measure of said medial surface taken in a plane perpendicular to the longitudinal axis of the implant is greater than a measure of said lateral surface taken in the same plane and a distal portion of the stem comprises an anterior surface, a posterior surface, a medial surface, and a lateral surface wherein a measure of said lateral surface taken in a plane perpendicular to the longitudinal axis of the implant is greater than a measure of the medial surface taken in the same plane.

    Abstract: A trial system for an implantable joint replacement includes a guide assembly having a baseplate and a guide plate, the guide plate translatable relative to the base plate along a straight path while directly connected to the baseplate. A first adjustment mechanism may selectively control the translational juxtaposition of the guide plate relative to the baseplate. The guide plate may further be rotatable relative to the baseplate around a rotation axis. A second adjustment mechanism may selectively control the rotational juxtaposition of the guide plate relative to the baseplate, and can lock the plates together. The rotation axis may be medially offset from the center of the guide assembly. The guide plate provides in situ positionable cutting guidance for implantation of prosthetic joint components. The system may further include an articulating insert trial to determine preferred joint alignment, implantable insert configuration and/or positioning of the guide plate.

    Abstract: A knee prosthesis including a femoral implant, a tibial implant, a tibial insert and a cam post. The femoral implant is secured to a femur and has a gap for receiving a natural PCL. The tibial implant is secured to a tibia. The tibial insert comprises a medial cavity with a rotational axis. The tibial insert has articulating surfaces that match the contours of the condyles of the femoral implant and a notch for retaining the natural PCL. The tibial insert has a medial boss that aligns with the medial cavity allowing it to rotate about the rotational axis. A post is secured to the tibial implant and enters a hole of the tibial insert providing anterior and posterior stops for the rotation of the tibial insert about the rotational axis.

    Abstract: A tibial insert includes a base and a post extending from the base along a longitudinal axis. The post has a medial surface, a lateral surface, and a height along the longitudinal axis. The medial surface has a medial section, and the lateral surface has a lateral section oriented substantially parallel to the medial section. The medial section and the lateral section each have a width in a substantially anterior-posterior direction that is sufficient to enable varus/valgus constraint over a flexion/extension range from extension to about 90 to 120 degrees of flexion when the tibial insert is mated with a femoral component.

    Abstract: A knee prosthesis (410) including femoral (412) and tibial (414) implants, a tibial insert (416) and a cam post assembly (419). The femoral implant is secured to a femur and has a cam feature and condyles. The tibial implant is secured to a tibia. The tibial insert has articulating surfaces that match the contours of the condyles of the femoral implant, and may have a medial boss that aligns with the tibial implant to provide rotation about a medially displaced rotation axis. A cam post is secured to the tibial implant and passes through a channel of the tibial insert. A motion limiting structure provides limits to motion between the tibial insert and the tibial baseplate. The cam post assembly interacts with the femoral implant cam feature (444) and allows more anatomically correct rollback and femoral external rotation during knee flexion, and varus/valgus support to the femur.

    Abstract: Certain versions generally provide an improved tibial base member (for example, but not limited to, 10) comprising keel portions (for example, but not limited to, 14a, 14b, 14c) that allow one or both cruciate ligaments to be preserved. Other versions provide improved lateral and/or medial inserts (for example, but not limited to, 110, 210) having a mesial lip (for example, but not limited to, 118, 128) that helps relieve and/or prevent impingement between the femoral component (for example, but not limited to, 400) and the tibial eminence. Other versions provide improved femoral components (for example, but not limited to, 400) having various chamfers (for example, but not limited to, 404, 410, 470) to provide additional clearance with respect to the tibial eminence and posterior cruciate ligament without decreasing bone coverage.
