Abstract

Custom made guides or patient specific instruments (PSI) for knee replacement is currently used to replace or guide conventional instruments by pin locating techniques. All currently available PSI techniques are company specific and can only be used for certain implants produced by the specific company. This new method is meant to integrate important parts of conventional instruments to the parts or templates of PSI. The invention includes 10 different methods and techniques to fit currently available conventional instruments regardless of the implant manufacturers. The integration is used to transfer the preoperative planning built in PSI to different pieces of conventional instruments allowing the machining (cutting and fashioning) of bone according to the preoperative plan. Using the specific software, these methods are modified to fit any new cutting blocks or conventional instruments that will be introduced in future. The same principles are used for other joint replacement.
