This study investigated the accuracy and reliability of using full-length lower limb radiographs to measure alignment outcomes of computer-assisted total knee arthroplasty. Simulated radiographs were created from cadaveric whole leg CT scans. Three analysts performed repeated measurement of the hip-knee-ankle (HKA) angle, blinded to the ID of the subject and image repetition. In addition, simulated radiographs with internal- /external- limb rotation were measured to assess sensitivity of the
