Patient Selectable Joint Arthroplasty Devices and Surgical Tools

Abstract

A patellar 3-D guidance tool includes a template. The template includes at least one contact surface for engaging a surface of the patella. The at least one contact surface substantially conforms with the surface associated with the patellar. At least one guide aperture directs movement of a surgical instrument, wherein the shape and/or position of the guide aperture is based, at least in part, on three or more anatomic reference points associated with the patellar.

What is claimed is: 
     
         1 . A method of using a surgical system for joint arthroplasty in a hip joint of a patient, comprising:
 referencing one or more anatomic landmarks using surgical navigation;   placing an acetabular jig by engaging a contact surface of the acetabular jig with a corresponding surface portion of the hip joint, wherein the acetabular jig includes one or more navigation markers;   determining a position and/or orientation of the acetabular jig relative to the one or more anatomic landmarks; and   adjusting the position and/or orientation to achieve a desired position and/or orientation of the acetabular jig.
