Abstract: Methods, systems and devices for pre-operatively planned total or partial joint surgery including, for example, anatomic and reverse shoulder surgery guides and implants. There are also methods for pre-operative planning methods for designing glenoid implants and prostheses, particularly with patient-specific augmentation, based on considerations of multiple factors affecting the outcome of a selected reverse or anatomic shoulder surgery. There are also described methods of performing total or partial joint surgery, including anatomic or reverse shoulder surgery, using surgery guides and implants in patients undergoing joint surgery.

Abstract: A powered device augments a joint function of a human during a gait cycle using a powered actuator that supplies an augmentation torque, an impedance, or both to a joint. A controller estimates terrain slope and modulates the augmentation torque and the impedance according to a phase of the gait cycle and the estimated terrain slope to provide at least a biomimetic response. The controller may also modulate a joint equilibrium. Accordingly, the device is capable of normalizing or augmenting human biomechanical function, responsive to a wearer's activity, regardless of speed and terrain, and can be used, for example, as a knee orthosis, prosthesis, or exoskeleton.

Abstract: A system and method for improving mechanical assemblies, such as prosthetic implants, intended to be installed in living tissue such as bone. Force-imparting devices are adapted and may include angularity, which may be introduced with specialized additive manufacturing, which may impart congruent cross-sections while providing variable stiffness. In some cases, the variable stiffness may be “stretchy” in a longitudinal direction and “rigid” in a radial directional which may provide an assembly bias. Additive manufacturing may allow the material of a prosthesis to be varied (e.g., density/porosity) to create variable stiffness over a length.

Abstract: A knee prosthesis for total knee replacement has femoral and tibial joint components. The femoral component has a medial condyle, a lateral condyle and an intercondylar recess between the condyles. The condyles in sagittal profile both have spiral outer surfaces, wherein the increasing anterior-to-posterior radii of curvature for the medial condyle is smaller than the corresponding radii of curvature for the lateral condyle. The tibial component has shallow concave medial and lateral condyle surfaces for receiving corresponding condyles of the femoral component as bearing surfaces when the femoral and tibial components are biased together under applied tension by ligaments. Posterior portions of each femoral condyle that contact the corresponding tibial condyle up to 90° flexion are substantially spherical in shape, with gradually increasing radii in coronal profile as flexion increases, while the anterior portions beyond 90° flexion are substantially elliptical in shape in coronal profile.

The cavity is sized to receive a femoral head of a femoral prosthetic component. The inner wall includes a curved surface extending inwardly from the outer rim to an inner end, and a semi-spherical surface connected to the inner end of the curved surfac. The inner wall is shaped to resist dislocation of the femoral head component from the cavity and permit the femoral head component to articulate over a range of motion.

Abstract: A knee prosthesis for total knee replacement has femoral and tibial joint components. The femoral component has a medial condyle, a lateral condyle and an intercondylar recess between the condyles. The condyles have in sagittal profile a spiral outer surface with increasing anterior-to-posterior radii of curvature, such as radii that follow a Fibonacci sequence ratio per every quadrant.

Abstract: An impaction cradle (50) for supporting a femoral (10) or tibial (70) implant on a planar support surface such as a tabletop. The impaction cradle can orient the femoral or tibial implant on the impaction cradle such that an attachment feature of the implant for an intramedullary stem or metaphyseal sleeve is aligned with a vertical plane or parallel to the true vertical axis. In this position, the intramedullary stem or metaphyseal sleeve can be impacted along a generally vertical axis to drive the intramedullary stem or metaphyseal sleeve along an impaction axis parallel to a true vertical axis or positioned within a vertical plane. The generally vertical impaction angle can be easier for medical practitioners to accurately impact the intramedullary stem or metaphyseal sleeve, which lowers the risk of damage to the intramedullary stem, metaphyseal sleeve, or the femoral or tibial implant.
