Abstract

Study DesignRetrospective Cohort Study.ObjectivesWith an aging population, the burden of concomitant joint disease continues to rise. The effects of hip OA on lumbar fusion outcomes are underexplored. Therefore, this study aimed to: (1) describe demographic differences between Osteoarthritis (OA) patients and those without OA; (2) assess perioperative differences; and (3) compare patient-reported outcome measures (PROMs).MethodsA retrospective review of a single academic tertiary center was performed (2016-2025). Patients undergoing lumbar fusion with isolated hip OA or no diagnosis of OA, and 12-month ODI scores were included. Patients with prior arthroplasty were excluded. Kellgren-Lawrence scores were collected through chart review or graded on x-ray when missing. Patients were stratified based on the presence of Hip OA. Bivariate comparison was performed as appropriate. Multivariable regressions were performed to identify independent predictors of PROMs.ResultsA total of 271 patients were included (No OA: 229; OA: 42). There were significant differences between groups regarding age (71.8 versus 60.2 years,
