An orthopaedic prosthetic includes a femoral component including a pair of condyles spaced apart to define an intercondylar notch. A tibial component includes a tray and a platform pivotally coupled to the tray. A modular insert is configured to be selectively coupled to the femoral component to couple the femoral component to the tibial component.

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.

Methods and systems are provided for a hinge knee system. A hinge knee system may comprise a femoral component; an insert; a tibial tray configured to be coupled to the insert; a tibial bushing configured to be disposed between the tibial tray and the insert; a poly locking screw configured to secure the tibial tray to the insert; a hinge box configured to be disposed between the femoral component and the insert; one or more cross-pin bushings configured to be disposed within the hinge box; a cross-pin configured to secure the hinge box to the femoral component; a hinge post configured to couple the hinge box to the tibial tray; and a hinge post set screw configured to secure the hinge box to the hinge post.

An orthopaedic prosthesis system includes a femoral component configured to be attached to a distal end of a patient's femur. A tibial tray is configured to be attached to a proximal end of a patient's tibia. A tibial insert is configured to be positioned between the femoral component and the tibial tray. An elongated pin rotatably couples the tibial insert to the femoral component.

A two-part joint replacement device for replacing damaged soft joint tissue, such as a meniscus or cartilage tissue. In one form, the device may include a free floating soft joint tissue replacement component comprising a first tissue-interface surface shaped to engage a first anatomical (bone and/or cartilage) structure of a joint having damaged soft tissue. The device may also include a free floating rigid base component comprising a second tissue-interface surface shaped to engage a second anatomical (bone and/or cartilage) structure of the joint. The free floating soft joint tissue replacement component may be shaped to slidably interface with the rigid base component. In another form, the free floating soft joint tissue replacement component and the rigid base component are fixed together.

An orthopaedic surgical instrument system that includes an orthopaedic surgical instrument adapted to be positioned on a proximal end of a patient's tibia, and a tibial bearing trial assembly, and a tibial evaluation component, and a tibial base trial component configured to be coupled to the orthopaedic surgical instrument. A tibial evaluation component includes a base plate and a generally Y-shaped posterior buttress extending upwardly from a superior surface of the base plate, such that the posterior buttress of the insert component is configured to be received in the opening of the tibial bearing trial assembly to prevent rotation of the tibial bearing trial component relative to the tibial base trial component.

A method of navigating a cutting instrument, via a computer system, the method comprising: (a) mounting a patient-specific anatomical mapper (PAM) to a human in a single known location and orientation, where the PAM includes a surface precisely and correctly mating with a human surface correctly in only a single location and orientation; (b) mounting a reference inertial measurement unit (IMU) to the human; (c) operatively coupling a guide to the PAM, where the guide includes an instrument inertial measurement unit (IMU) and at least one of a cutting slot and a pin orifice; (d) outputting data from the reference IMU and the instrument IMU indicative of changes in position and orientation of the guide with respect to the human; (e) repositioning the guide with respect to the human to a position and an orientation consistent with a plan for carrying out at least one of a cut and pin placement; and, (f) visually displaying feedback concerning the position and orientation of the guide with respect to the human using data output from the reference IMU and the instrument IMU, which data is processed by a computer program and the computer program directs the visually displayed feedback.

The present disclosure is a femoral preparation guide and a kit of surgical components related to the femoral preparation guide. The femoral preparation guide is for use on a condyle of a femur during a surgical procedure in which the condyle receives a femoral condylar implant. The femoral preparation guide includes a posterior portion for fitting over a posterior region of the condyle and a distal portion for fitting over a distal region of the condyle. The distal portion is at an angle relative to the posterior portion. The distal portion includes first and second resections slots for receiving cutting tools that provide two resections of the condyle. The first and second resections slots being at angles relative to each other.

An orthopedic knee prosthesis includes a femoral component, a tibial bearing, a tibial component, a first magnetic portion associated with the femoral component and including a first pole having a first pole polarity the first magnetic portion not physically interrupting any articulating portion of the curved medial condyle surface or curved lateral condyle surface, and a second magnetic portion associated with one or both of the tibial bearing and/or the tibial component and including a second pole having a second pole polarity, the second pole polarity the same as the first pole polarity, the second magnetic portion not physically interrupting any articulating portion of the concave medial bearing surface or concave lateral bearing surface, wherein the first pole and the second pole are in sufficient proximity to each other such that a magnetic repulsive force is present therebetween.

A kit of parts for use in a unicondylar knee replacement procedure having a keel punch, a unicondylar tibial trial and an impactor. The keel punch including a cutting formation on the inferior side configured to form a slot in a resected part of a patient's tibia, and a first attachment formation on the superior side. The unicondylar tibial trial having a body defining a slot passing therethrough between an upper surface and a lower surface that extends parallel to a longitudinal axis extending from an anterior end to a posterior end of the body. The slot configured to slidably receive the keel punch. The impactor includes a second attachment formation and is releasably attachable to the keel punch by slidingly engaging the second attachment formation with the first attachment formation. An assembly for use in and methods of trialing during a unicondylar knee replacement procedure are also disclosed.
