    摘要： Methods of using implant devices are provided herein. The implant devices of the methods herein have an articular end and a stem, the stem having an oval-shaped cross-section. The articular end has an upper surface, a side surface, and a lower surface. The upper surface and lower surface each intersect the side surface. The upper surface has a first surface curvature, a central surface curvature, and a second surface curvature. The stem extends from the lower surface in a direction away from the upper surface of the articular end.

    摘要： Patient specific implants and instrumentation for replacing a portion of a patella. Methods for producing patient specific implants and instrumentation include conducting imaging studies of the patient's native patella, deriving measurements of the patella and surrounding soft tissues from the imaging studies, manufacturing customized implants and instrumentation specific to the derived measurements, and implanting a customized implant using the customized instrumentation. Patient specific instrumentation includes: a patellar clamp ring, an anterior clamp, a restraining arm, a posterior clamping surface, a dual bore reaming collet, a reamer, a reaming depth gauge, and a resection cutting guide. Patient specific portions of a patellar implant include: topography of the posterior articular surface, facet angle, shape and dimensions of the anterior attachment surface, implant length, implant width, implant thickness and the outer perimeter shape of the implant.

    摘要： Systems and methods for providing deeper knee flexion capabilities, more physiologic load bearing and improved patellar tracking for knee prosthesis patients. Such systems and methods include (i) adding more articular surface to the antero-proximal posterior condyles of a femoral component, including methods to achieve that result, (ii) modifications to the internal geometry of the femoral component and the associated femoral bone cuts with methods of implantation, (iii) asymmetrical tibial components that have an unique articular surface that allows for deeper knee flexion than has previously been available, (iv) asymmetrical femoral condyles that result in more physiologic loading of the joint and improved patellar tracking and (v) modifying an articulation surface of the tibial component to include an articulation feature whereby the articulation pathway of the femoral component is directed or guided by articulation feature.
