Abstrakt: Introduction: Unicompartmental knee arthroplasty (UKA) has been shown to improve pain and function in appropriately selected patients. Limited data exists regarding outcomes and complication rates following UKA among octogenarians.
Methods: The PearlDiver Mariner database was queried for patients undergoing primary UKA between 2010-2022. Patients < 80 years old were matched 4:1 to the octogenarian cohort (≥80 years old) by sex, year, Elixhauser Comorbidity Index (ECI), tobacco use, obesity, and diabetes. A total of 1,334 octogenarians and 5,313 controls were included in our analysis. Multivariate logistic regression was utilized to compare medical complications at 90-days post-operatively and surgical complications at 1- and 2-years post-operatively. Our regression analysis controlled for sex, ECI, tobacco use, obesity, and diabetes.
Results: Octogenarians had an increased risk of acute kidney injury (OR: 2.306, 95% CI: 1.393-3.749; p < 0.001), pneumonia (OR: 2.367, 95% CI: 1.301-4.189; p = 0.003), UTI (OR: 1.846, 95% CI: 1.304-2.583; p < 0.001), ED visits (OR: 2.229, 95% CI: 1.586-3.105; p < 0.001), and any complication (OR: 1.575, 95% CI: 1.304-1.895; p < 0.001) at 90-days post-operatively. Octogenarians had lower odds of all-cause revision at 2-years (OR: 0.607, 95% CI: 0.382-0.923; p = 0.026). No differences were demonstrated between cohorts in rates of PJI (OR: 0.832, 95% CI: 0.334-1.796; p = 0.664), periprosthetic fracture (OR: 0.516, 95% CI: 0.120-1.520; p = 0.289), or aseptic loosening (OR: 0.285, 95% CI: 0.045-1.203; p = 0.088) at 2-years.
Discussion: These findings suggest that despite an increased risk of certain medical complications within the acute post-operative period, octogenarians undergoing UKA experienced similar rates of surgical complications to younger matched controls at 2-year follow-up.
