Objective: To explore the correlation between the horizontal deviation of the coronal lumbar spine and the lower limb force line in knee osteoarthritis (KOA).: Retrospective analysis of 233 KOA cases (47 males and 186 females, aged 50 to 83 years old, with an average of [61.55 ± 8.72]) admitted from October 1, 2022, to December 31,2023,were analyzed.Bilateral hip, knee, and ankle angles (HKA), mechanical axis offset distance (MAD), joint angle (JLCA), lumbar-knee offset distance (LKOD, self-test angle, reflecting the difference in the position of the bilateral knee joint relative to this lumbar vertebra), Western Ontario and McMaster Universities Arthritis index score(WOMAC)and baseline data records were assessed for all patients.Results: WOMAC was correlated with L1, L2, and L3 in LKOD (P<0.05, r= 0.240, 0.362, and 0.386) but not with L4 and L5 (P> 0.05). WOMAC was also associated with HKA, MAD, and JLCA on the affected side (P<0.05, r=-0.127, 0.140, 0.135). Unaffected side and d values were not associated with HKA, MAD, and JLCA (d value represents the absolute value of the difference between unaffected side and affected sides, which represents the overall change in both lower limbs) (P > 0.05). L1-5 in LKOD was associated with HKA and MAD d values (P<0.05); LKOD was not correlated with HKA, MAD and JLCA on the affected side.Lumbar horizontal deviation is a risk factor affecting all angles in both lower limbs and also a risk factor for aggravating knee bone and joint symptoms. The influence of the horizontal direction change of the 2 lumbar spine on KOA, especially the change of L3, can be prioritized in the clinical treatment and research of KOA.
