The Kaplan-Meier implant survivorship estimate curves with revision for any reason as the end point show an apparent difference (p = 0.07) in revision rates at 5 years for OA (56%; 95% confidence interval, 26%–86%), compared with APC (91%; 95% confidence interval, 74%–100%) and EP (100%; 95% confidence interval, not applicable) reconstructions. Inverted triangles (OA), plus signs (APC), and solid circles (EP) along the curves represent patients censored owing to patient death or loss to followup.
