摘要： A system and method for pre-operatively optimizing a fit of an orthopaedic implant relative to a particular individuals anatomy is provided. The method includes: receiving information including a three-dimensional anatomic model of the individuals anatomy; computing a periphery of a simulated resection portion of the anatomic model without reference to any abnormal morphology; identifying a preliminary size for an orthopaedic implant component for use on the simulated resection surface; initially positioning the orthopaedic implant model relative to the simulated resection portion; generating random point sets around the peripheries of the simulated resection portion and the orthopaedic implant model; utilizing a position optimizer to determine whether the position of the orthopaedic implant periphery relative to the simulated resection portion periphery is optimal; determining whether the selected orthopaedic implant model results in overhang; and verifying the position of the orthopaedic implant and/or the size of the orthopaedic implant.

摘要： A tibial insert includes a base and a post extending from the base along a longitudinal axis. The post has a medial surface, a lateral surface, and a height along the longitudinal axis. The medial surface has a medial section, and the lateral surface has a lateral section oriented substantially parallel to the medial section. The medial section and the lateral section each have a width in a substantially anterior-posterior direction that is sufficient to enable varus/valgus constraint over a flexion/extension range from extension to about 90 to 120 degrees of flexion when the tibial insert is mated with a femoral component.

摘要： Systems, methods and devices for tensioning posterior cruciate ligaments during cruciate or bi-crucia†e ligament-sparing arthroplasty. Non-limiting examples of such systems may include at least one series of tibial inserts of equal size; the at least one series of tibial inserts having at least one set of tibial inserts of equal thickness. The at least one set of tibial inserts of equal thickness may include at least two tibial inserts having different geometries in a posterior portion, the different geometries being configured to change the tension in the posterior cruciate ligament (PCL). The different geometries in the posterior portions of the tibial inserts are configured so as to allow the posterior cruciate ligament to be tensioned or loosened independently of the tibial insert thickness and/or size. By providing different posterior geometries for each insert within a set of a series, a surgeon may be provided with more flexibility in choosing an insert that satisfies stability requirements in a non-invasive manner.
