MARKING TEMPLATE FOR INSTALLING A CUSTOM REPLACEMENT DEVICE FOR RESURFACING A FEMUR AND ASSOCIATED INSTALLATION METHOD

摘要

A replacement device for resurfacing a joint surface of a femur and a method of making and installing such a device is provided. The custom replacement device is designed to substantially fit the trochlear groove surface, of an individual femur, thereby creating a “customized” replacement device for that individual femur and maintaining the original kinematics of the joint. The top surface is designed so as to maintain centrally directed tracking of the patella perpendicular to the plane established by the distal end of the femoral condyles and aligned with the center of the femoral head.

主权项

1. A method of manufacturing a surgical instrument, the method comprising:
receiving pre-operative data related to a particular patient defining at least a portion of a three-dimensional tissue contacting geometry of a surgical instrument, the surgical instrument including a surgical tool guide, wherein the received pre-operative data is based on three-dimensional geometry of a distal-anterior portion of a femur and a pre-operatively planned spatial arrangement of the surgical tool guide relative to the distal-anterior portion; and manufacturing the surgical instrument using the received pre-operative data, thereby configuring the surgical instrument based on the received pre-operative data to mount to the particular patient's femur in a pre-defined spatial arrangement, wherein manufacturing the surgical instrument includes manufacturing the three-dimensional tissue contacting geometry and the surgical tool guide, such that the surgical tool guide is in a pre-defined spatial arrangement relative to the three-dimensional tissue contacting geometry.
