AKS Clinical Score over time for patients with revisions (n = 46) and patients without revisions (n = 675). ANOVA showed no difference in the AKS Clinical scores between groups at 0 months (Student-Newman-Keuls P > 0.05). There was no difference in AKS Clinical scores between the latent and acute groups at 3–18 months, but the non-revision group differed significantly from both the latent and acute groups at these time intervals (p = 0.05)
