Implant assemblies, systems, kits, and methods for replacing a knee joint may include a universal femoral trial component for preparing and trialing a femoral bone of a patient to receive a plurality of different femoral implant types. The assembly may include a body and drill guide and an attachment mechanism including first and second compressible tabs and a rotatable handle operationally connected to the first and second tabs. The universal femoral trial component may be configured to receive any of a plurality of femoral bone preparation attachments and any of a plurality of femoral trial attachments in order to facilitate the preparation and trialing of the femoral bone to receive the plurality of different femoral implant types.

Universal femoral trial system and methods

A knee joint prosthesis may be for implantation in a knee of a patient. The knee prosthesis may comprise a tibial component configured to be implanted on the tibia and a femoral component configured to be implanted on the femur. The femoral component may comprise a medial condyle with a medial articulation surface and a lateral condyle with a lateral articulation surface. The medial articulation surface and the lateral articulation surface may be shaped substantially symmetrically to each other across a femoral component plane bisecting the femoral component. The tibial component may comprise an articulation surface with a medial articulation side configured to articulate with the medial articulation surface and a lateral articulation side configured to articulate with the lateral articulation surface. The medial articulation side and the lateral articulation side may be shaped substantially asymmetrically to each other across a tibial component plane bisecting the tibial component.

Knee prosthesis

A knee joint prosthesis system for implantation in a first knee joint of a patient. The first knee joint has a condition. The knee joint prosthesis system includes a tibial baseplate component, a femoral component having a femoral articulation surface, and a tibial insert. The tibial insert includes a tibial articulation surface configured to articulate with the femoral articulation surface. The tibial articulation surface includes a medial tibial compartment asymmetrical to a lateral tibial compartment. The tibial articulation surface is shaped to cooperate with the femoral articulation surface to adapt kinematics of the first knee joint having the condition and the tibial articulation surface is also suitable for implantation in a second knee joint on a second side, the second knee joint lacking the condition.

Implant assemblies, systems, and methods for replacing a knee joint may include a method of revising a knee joint prosthesis implanted in a knee of a patient to provide increased stability to the knee joint prosthesis by replacing a first tibial insert with a second tibial insert that provides more constraint that the first tibial insert. A knee joint prosthesis system and kit are also provided that may include a tibial baseplate component, a femoral component, and a tibial insert that is selectively interchangeable with other tibial inserts to provide varying levels of constraint and stability to the knee joint prosthesis.

Implant assemblies, systems, kits, and methods for replacing a knee joint may include a universal femoral trial component for preparing and trialing a femoral bone of a patient to receive a plurality of different femoral implant types. The universal femoral trial component may be configured to receive any of a plurality of femoral bone preparation attachments and any of a plurality of femoral trial attachments in order to facilitate the preparation and trialing of the femoral bone to receive the plurality of different femoral implant types.

A knee arthroplasty system may have a femoral joint prosthesis with a femoral bone engagement surface with an anterior portion, a posterior portion, and a distal portion that connects the anterior portion to the posterior portion. A first femoral anchoring member may protrude from the distal portion, and may be connected to the anterior portion with a primary femoral web. A tibial resection guide may have a base member and a guide member with a slot that guides a cutting blade to resect the tibial plateau. The guide member may slide along an arcuate path relative to the base member.

Knee arthroplasty systems and methods

A tibial tray component includes a tibial tray portion with a post portion protruding from a bone-contacting side of the tibial tray portion. The tibial tray portion may include ribs extending along the bone-facing side in areas of high stress during the gait cycle. The post portion may include at least one fin projecting outwardly from the post portion and extending along a portion of the length of the post portion. A cut block assembly includes a cut block and at least one pin. The cut block may include several mounting locations for the pin. The pin may include an anti-rotation portion and a tapered free end.
