Abstract

INTRODUCTION: This study documented the incidence of incidental findings from preoperative computerized-tomography (CT) scans obtained for robotic-arm-assisted total joint arthroplasty (TJA) and its effect on patient management.

METHODS: A retrospective review was conducted for patients who underwent robotic-arm assisted primary total hip arthroplasty (THA) or total knee arthroplasty (TKA) from 2016 to 2020. All patients obtained preoperative CT scans which were formally read by fellowship-trained musculoskeletal radiologists. CT's were flagged with incidental findings and those requiring physician follow-up were identified as significant.

RESULTS: A total of 1519 patients (mean age, 66 years ±9; 849 females) were evaluated. Seventy-three (4.81%) patients had incidental CT scan findings, and 25 (1.65%) patients had significant incidental findings. Four patients required additional imaging and two patients required intervention.

CONCLUSION: This study found a 4.81% incidence of incidental findings from preoperative CT scans for robotic-arm-assisted THA and TKA. Of these findings, less than 2% required physician follow-up and less than 1% required intervention. With the increasing popularity of robotic-arm assisted total joint arthroplasty, it is important to consider the necessity of detection and management of associated incidental findings from preoperative CT scans.
