    Abstract: A modular augment cone system and methods of implanting the modular augment cone system. The system includes a main body cone a first cutout in the cone wall, and including a proximal end, a distal end, and a cone wall extending between the proximal and distal ends. A portion of the cone wall proximal to the first cutout includes an attachment feature. A first augment cone is positionable in the first cutout, the first augment cone including an attachment feature configured to mate with the attachment feature of the cone wall to attach the first augment cone into the first cutout. The main body cone can include a second cutout in the cone wall. In such systems, the modular augment cone system can include a second augment cone configured to mate with an attachment feature of the cone wall to attach the second augment cone into the second cutout.

    Abstract: 一种膝关节系统、胫骨假体、胫骨托假体系列及胫骨托假体组。胫骨托假体组包括至少两个型号不同胫骨托假体，每个骨托假体均设有用于与胫骨连接的立柱(11,12)以及龙骨(13)，每个骨托假体还均设有第一基准面(21)以及第二基准面(22)，第二基准面(22)与第一基准面(21)相交，当不同型号的胫骨托假体的第一基准面(21)对齐并且第二基准面(22)对齐时，不同型号的胫骨托假体的立柱(11,12)重合并且龙骨(13)重合。胫骨托假体组提高了胫骨托假体的固定稳定性，减小了胫骨托假体松动发生概率，同时无需重新开立柱孔以及龙骨槽，提高了手术操作效率，减少了手术时间，降低了患者感染的发生概率。

    Abstract: A knee prosthesis and a method of selecting for a particular patient a knee prosthesis from an inventory of available knee prostheses or from 3D knee prosthesis models is provided. The method includes the steps of (a) parameterizing a knee prosthesis according to well-defined and independent knee joint compartments, (b) generating a large number knee shapes in the form of 3D knee prosthesis models which reproduce the 3D shape asymmetries of each individual knee, thereby enabling the replication of the knee motion of essentially any patient by generating shapes which vary the shape parameters (surface and dimension) of at least one of those compartments and storing these 3D knee prosthesis models in a database, and (c) studying the patient's pathology and developing pre -pathological knee prosthesis criteria matching the patient's needs. Using a planning algorithm, a suitable knee prosthesis may be selected among an inventory of existing knee prostheses or the large number of knee shapes, the prosthesis or shape selected best meeting the patient's needs as determined by the study.

    Abstract: Unicompartmental tibial components are described herein. A first unicompartmental component (10) comprises a plate (12) having a bearing surface (18) and an opposing surface (22) that is configured to be secured to a proximal end of a patient's tibia, wherein the plate further comprises an anterior end (24), an outer side (25), a posterior end (26) and an inner side (27), wherein a mediolateral width W of the plate is defined between the outer and inner sides, and a longitudinal anteroposterior axis (28) extends between the anterior and posterior ends approximately one third of the width of the plate (i.e. 1/3W) from the lateral side, and defines a longitudinal axis length L of the plate. A first elongate peg (14) protrudes from the opposing surface in the anterior portion, the first elongate peg defining a first peg axis (32). A second elongate peg (16) protrudes from the opposing surface in the anterior portion, the second elongate peg defining a second peg axis (34). The first and second peg axes are disposed at an angle of 45-70 degrees with respect to the longitudinal anteroposterior axis and are substantially parallel to one another such that the first and second pegs protrude posteriorly as well as distally with respect to the plate. An anterior portion of the plate comprises a part of the plate defined by an anterior 60% or less of the longitudinal axis length L, whilst a posterior portion of the plate comprises a part of the plate that is defined by the remaining posterior 40% or more of the longitudinal axis length L. The posterior portion of the opposing surface is free from pegs or other fixation devices, and the first and second elongate pegs are located more than half of the mediolateral width W of the plate from an outer edge of the plate. The component is configured for cementless fixation using an interference fit. Also described is a method of installation and a tool suitable for use in installation.
