摘要： 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 cam feature and condyles. 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. The tibial insert has a medial boss that aligns with the medial cavity allowing it to rotate about the rotational axis. A cam post is secured to the tibial implant and passes through a channel of the tibial insert providing anterior and posterior stops for the rotation of the tibial insert about the rotational axis. The cam post interacts with the femoral implant cam feature and, with the tibial insert, allows more anatomically correct rollback and femoral external rotation during knee flexion.

摘要： 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 mounted on the guide assembly to determine preferred joint alignment and/or optimal positioning of the guide plate.

摘要： Knee prostheses featuring components that more faithfully replicate the structure and function of the human knee joint in order to provide, among other benefits: greater flexion of the knee in a more natural way by promoting or at least accommodating internal tibial rotation in a controlled way, replication of the natural screw home mechanism, and controlled articulation of the tibia and femur respective to each other in a more natural way. In a preferred embodiment, such prostheses include an insert component disposed between a femoral component and a tibial component, the insert component preferably featuring among other things a reversely contoured posterolateral bearing surface that helps impart internal rotation to the tibia as the knee flexes. Other surfaces can also be specially shaped to achieve similar results, preferably using iterative automated techniques that allow testing and iterative design taking into account a manageable set of major forces acting on the knee during normal functioning, together with information that is known about natural knee joint kinetics and kinematics.

摘要： A system and method for placing a prosthetic acetabular cup within an acetabulum are disclosed. The system may comprise an acetabular cup with an eccentric socket. The acetabular cup may be substantially hemispherical with a cup rim and a portion of the cup rim removed defining a relief. The cup may accommodate a concentric liner in an eccentric position. Screw apertures may be present on the periphery of the cup and the screw trajectories may converge toward the dome of the cup. The cup is attached to a tool which is offset relative to the cup because of the substantially eccentric socket. The relief, when the cup is secured to the acetabulum, is positioned substantially anterior and the socket is positioned more posterior to provide a more natural center of rotation of a femoral head within the socket. The first relief reduces impingement of the acetabular cup on soft tissue.
摘要翻译：公开了一种用于将假体髋臼杯放置在髋臼内的系统和方法。该系统可以包括具有偏心插座的髋臼杯。髋臼杯可以是具有杯形边缘的大致半球形，并且杯形边缘的一部分被移除，从而限定了浮雕。杯子可以容纳位于偏心位置的同心衬套。螺丝孔可能存在于杯的周边上，并且螺钉的轨迹可以朝着杯的圆顶会聚。由于基本上是偏心的插座，杯子被附接到相对于杯子偏移的工具。当杯被固定到髋臼上时，浮雕的位置基本上位于前方，并且插座位于更靠后的位置，以在插座内提供股骨头的更自然的旋转中心。第一个缓解减轻髋臼杯对软组织的冲击。

摘要： A trial system for an implantable joint replacement includes a guide assembly having a baseplate and a guide plate, the guide plate rotatable relative to the base plate about a rotation axis extending through the guide plate and the baseplate while directly connected to the baseplate. An adjustment mechanism is actuable to selectively control the rotational juxtaposition of the guide plate relative to the baseplate. The rotation axis may be medially offset from the center of the guide assembly. A single instrument may be used to rotate the guide plate relative to the base plate and lock the plates in the selected juxtaposition. The guide plate provides in situ positionable cutting guidance for implantation of prosthetic joint components. The system may further include an articulating insert trial mounted on the guide assembly to determine preferred joint alignment and/or optimal positioning of the guide plate.

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.
