Abstract

Computer-assisted surgery in total hip arthroplasty remains a cumbersome, time-consuming, and expensive tool without proven clinical benefit. Current imageless computer-assisted technology systems have attempted to account for the functional position of the component, including the combination of cup alignment in bone and pelvic tilt. However, pelvic tilt has been shown to change significantly before and after total hip arthroplasty, making optimal component positioning a moving target. Thus, while computer-assisted surgery clearly improves the anatomical position of the component during total hip arthroplasty, this has not improved dislocation rates, range of motion, function, or outcome scores in patients.
