DEVICE AND METHOD FOR FITTING AN ARTIFICIAL KNEE JOINT USING UNIVERSAL ELECTRONIC TEMPLATES WHICH CAN BE ADAPTED TO ALL ARTIFICIAL JOINTS

摘要

This invention is a device and a method for preparing a knee joint for a prosthesis in a patient undergoing TKA surgery for any knee implant (prosthesis). The device and the method are used in a universal and an open platform fashion for any currently available knee implant, all patient specific implants and any knee implants that could be produced in future.;The device is a patient specific instrument, which is based on a method comprising of image based (CT, MRI or computed X-ray) 3-D preoperative planning to design the templates (PSI) that are used to perform the knee surgery for any knee implant in a universal and open platform fashion.

主权项

1. A device for preparing a knee joint for a prosthesis in a patient undergoing total knee arthroplasty (TKA) surgery for any knee implant (prosthesis) in a universal and open platform fashion, this device consists of two parts: a femoral part and a tibial both are designed in the form of cutting blocks that have locating probes, slits and a surface for bone cutting, guide for adjusting rotation and holes for pin fixation. The tibial part has a hole for the creation of the stem and a slit for the creation of the keel.
