摘要： A method for preoperatively characterizing an individual patient's biomechanic function in preparation of implanting a prosthesis is provided. The method includes subjecting a patient to various activities, recording relative positions of anatomy during said various activities, measuring force environments responsive to said patient's anatomy and affected area during said various activities, characterizing the patient's biomechanic function from said relative positions and corresponding force environments, inputting the measured force environments, relative positions of knee anatomy, and patient's biomechanic function characterization into one or more computer simulation models, inputting a computer model of the prosthesis into said one or more computer simulation models, and manipulating the placement of the prosthesis in the computer simulation using said patient's biomechanic function characterization and said computer model of the prosthesis to approximate a preferred biomechanical fit of the prosthesis.

摘要： Embodiments of the present invention provide patellar component designs that are optimally shaped to help reduce shear force and accommodate slight implantation error. Further, they help lessen anterior knee pain, particularly during deep-flexion activities and help ease the transition during the range of knee movement in a controlled way.
摘要翻译：本发明的实施例提供了最佳成形以有助于降低剪切力并适应轻微植入误差的髌骨部件设计。此外，它们有助于减轻前膝关节疼痛，特别是在深屈曲活动期间，有助于缓解膝盖运动范围内的过渡。

摘要： A system and method for pre-operatively optimizing a fit of an orthopedic 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 orthopedic implant component for use on the simulated resection surface; initially positioning the orthopedic implant model relative to the simulated resection portion; generating random point sets around the peripheries of the simulated resection portion and the orthopedic implant model; utilizing a position optimizer to determine whether the position of the orthopedic implant periphery relative to the simulated resection portion periphery is optimal; determining whether the selected orthopedic implant model results in overhang; and verifying the position of the orthopedic implant and/or the size of the orthopedic implant.
