Changes in lifetime risk of TKR over time for females. Whiskers indicate 95%CI; P < 0.05 for all 2003–2013 comparisons. For these estimates, simultaneous bilateral TKR was counted as one TKR procedure to avoid potential over-estimation of lifetime risk. Where staged bilateral TKR procedures were performed within the same year, only the first procedure was included in the dataset.
