Comparison of DXA results between different measurement sites and radiological OA-grades. A DXA T-scores of both hips (affected and unaffected leg) and the lumbar spine, B Z-scores, and C BMD. D Comparison of the hip T-scores of the affected leg, E unaffected leg, F and lumbar spine between individual Kellgren–Lawrence scores of the operated knee. Ordinary one-way ANOVA and Tukey’s multiple comparison test was used in all panels. Aff affected leg, Unaff unaffected leg, LS lumbar spine, T-score Hip_Aff Hip T-score of the affected leg, T-score Hip_Unaff Hip T-score of the unaffected leg, T-score_LS lumbar spine T-score. *p < 0.05, **p < 0.01, ***p < 0.0001
