Figure 4From: Patient and surgery related factors associated with fatigue type polyethylene wear on 49 PCA and DURACON retrievals at autopsy and revisionProbability curves for occurrence of fatigue-type wear. Probability curves for occurrence of fatigue-type wear with 95% confidence boundaries. Calculation was done via Kaplan-Meier survival estimates and plotted as cumulative hazard plot. Time course for autopsy and revision is not different (Log ranked test ns.) indicating that cumulative risk at a given time point was the same independently from group affiliation.Back to article page
