This study assessed the accuracy of preoperative digital templating for a second-generation cementless stem compared with its first-generation design. A prospective cohort of 100 consecutive patients who had undergone a primary total hip arthroplasty using a new second-generation cementless stem was compared with the prior 100 hips that had received the first-generation stem. The authors believe that the second-generation stem may allow equal or more accurate digital templating compared with its predicate design.
