Adequate bone quality is necessary for reliable cementless fixation during total knee arthroplasty (TKA). Hounsfield Units (HUs) can be a useful surrogate of bone density, and therefore a proxy of bone quality. We sought to determine whether HU would correlate with subjective intraoperative assessment of bone quality and hence use of cementless fixation. A retrospective review of patients who underwent a robotic-assisted TKA between June 2022 and June 2024 by a single surgeon was conducted. HU measurements were obtained at three regions of interest (ROI) within the tibial plateau on preoperative axial-CT scans. Patients were divided into cementless or cemented tibial implant fixation groups based upon subjective intraoperative bone quality assessment. Demographic data such as age, sex, and BMI were collected. The final cohort included 630 patients. Cementless fixation was used in 58.3% of cases. Cementless patients had a higher combined overall average HU measurement (152.7 vs. 105.6, p
