We propose a new guidance paradigm for computer-assisted orthop忙dic surgery, based on nonrigid registration of a patient to a standard atlas model. Such a method would save costs and time compared to CT-based methods, while being more reliable than current imageless navigation tools. Here, we consider application of this paradigm to knee arthroplasty.This work reports laboratory results of assessing the simplest nonrigid registration method, which is an affine transformation. Results from CT scans of 15 patients show the method is more repeatable than the standard mechanical guide rods in the frontal plane. The affine transformations also detected a potential difference between osteoarthritic patients and the normal population, which may have implications for the implantation of artificial knee components.
