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).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A 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.
