Abstract:INTRODUCTION Image-based navigation systems for total knee arthroplasty (TKA) require intra-operative registration of anatomical landmarks to the pre-operative images. Unfortunately, this process is long, tedious, and involves multiple steps with an optical tracking probe to bony identify landmarks. We hypothesized that use of a handheld laser scanner can achieve an accurate and fast registration of the cartilage surface. METHODS Magnetic resonance imaging (MRI) scans were obtained for six cadavers and image… Show more
