sPatient perception of computed tomography scans in robotic-assisted elective total knee and hip arthroplasty: A...

This study evaluates patient perceptions of radiation exposure from preoperative CT scans in robotic-assisted total joint arthroplasty (raTJA). It examines awareness of radiation risks, the impact of prior raTJA experience, and the role of education and previous CT scans in knowledge acquisition. Additionally, it explores patient preferences for CT scans despite radiation exposure.

A cross-sectional study was conducted with patients 21 years of age and older who were candidates for a raTJA. A 21-item questionnaire was distributed in an arthroplasty clinic to assess patient demographics, prior CT scan exposure, knowledge of radiation risks, and opinions on preoperative CT scans in raTJA.

Of the 155 respondents, 72.9 % were female, with a mean age of 64. The majority (80.7 %) were candidates for TKA, and 16.8 % for THA. While 53.6 % of participants knew that CT scans involve radiation exposure, 81 % were unaware of how much radiation a CT scan produces compared to X-rays. Among patients with prior raTJA, 62 % were aware of radiation risks. Patient knowledge of radiation exposure was not significantly associated with education level or prior CT scans (P > 0.05). Notably, over 90 % of patients preferred a preoperative CT if it enabled robotic assistance, even after learning about radiation exposure.

As robotic-assisted TJA becomes more widespread, understanding patient views on preoperative CT scans is increasingly essential. While awareness of radiation exposure was limited, most patients preferred CT imaging if it enabled robotic assistance, highlighting the need for improved education and communication regarding the risks and benefits.
