“… 6 , 10 , 36 Similarly, the risk of periprosthetic fracture in patients with dementia undergoing ATSA or RTSA was 2.1% and 6.3%, respectively, in this study, which is higher than seen in patients with BMI over 30 kg/m 2 , metabolic syndrome (including A1c >6.5%), or opioid dependence. 6 , 10 , 33 Finally, we found that patients with dementia had a dislocation risk of 2.1% in ATSA and 4.5% in RTSA. These findings for ATSA are similar to those seen in patients with BMI >30 kg/m 2 and A1c >6.5%, but higher than in patients with opioid dependence; for RTSA patients, the risk of instability is higher compared to all three of these other comorbid conditions.…”
