Abstract
Background
Aseptic loosening is a feared complication following total elbow arthroplasty (TEA); however, literature regarding factors that may contribute to this complication is limited. The aims of this investigation were to: (1) compare baseline demographics of patients who developed aseptic loosening following primary TEA; and (2) identify patient-specific risk factors for the development of loosening.
Methods
Retrospective analysis using a nationwide claims database was performed to identify patients who underwent primary TEA and developed aseptic loosening within 2 years (study n = 307, control n = 10,741). Multivariate regression analysis generated odds ratio (OR), 95% confidence interval (95% CI), and p-value of risk factors. p < 0.05 was considered statistically significant.
Results
Patients who developed aseptic loosening had significant differences in numerous demographics, including age (p = 0.0001), sex (p = 0.0251), and various comorbid conditions such as obesity (15.96% vs. 8.36%, p < 0.0001). Furthermore, the risk factors most associated with aseptic loosening were obesity (OR 1.65, 95% CI 1.18–2.28, p = 0.002), male sex (OR 1.51, 95% CI 1.13–2.00, p = 0.004), and concomitant opioid use disorder (OR 1.58, 95% CI 1.14–2.15, p = 0.004).
Discussion
This study is the first to identify demographics and patient-related risk factors associated with aseptic loosening following primary TEA. This evidence could be applied to the clinical setting in order to educate at-risk patients of this potential complication as well as inform their post-operative clinical management.
