Effect of THR and TKR surgery on intracellular H₂O₂ production of neutrophils (A) and monocytes (B). A, the points represent mean ± SD. p = 0.035, as determined by ANOVA following THR surgery. B, the points represent mean ± SD. p = 0.002, as determined by ANOVA following TKR surgery. Baseline vs day 1 postoperative following TKR (p = 0.011, as determined by pairwise comparisons) (*, p < 0.05 compared to baseline).
