: Computer Assisted Orthopedic Surgery (CAOS), developed to improve the alignment of the arthroplasty components, has increased in number significantly during the last decade. Some CAOS procedures rely on preoperative imaging, raising the possibility of and inter and intra observer variability affecting segmentations previously studied in a variety of other tissues and locations. However, despite the high prevalence of knee models and applications of knee joint models, the variability and repeatability of segmentation of knee not been previously investigated. Therefore, this study investigates the intra observer influence on semi automatic segmentation of the knee joint.
