Abstract: Lumbar spondylosis (LS) commonly coexists with knee osteoarthritis in older adults. We retrospectively identified 10 patients with advanced knee OA and radiographic LS from a prospective TKA cohort. All patients underwent primary total knee arthroplasty (TKA) and were evaluated preoperatively and at 6 months with the Oxford Knee Score (OKS) and Oswestry Disability Index (ODI), plus back pain VAS. At 6 months, mean OKS improved from 13.0 (±2.9) to 33.8 (±2.8), and mean ODI improved from 47.9% (±9.5) to 32.0% (±7.4). Back pain VAS likewise improved (mean 7.1→4.4). Nine of 10 patients had clinically meaningful ODI improvement; two with severe LS required spine intervention post-TKA. These findings indicate that although coexisting LS is common, most patients achieve substantial knee and back outcome gains after TKA. Surgeons should recognize LS comorbidity and counsel patients on realistic functional recovery.
