Abstract
To investigate patient factors influencing length-of-stay (LOS) after revision metal-on-metal (MoM) total hip arthroplasty (THA). We reviewed 23 hips undergoing revision of a MoM THA with minimum 2-year follow-up. A multiple linear regression was calculated to predict LOS using multiple variables. Average length of stay (LOS) was 2.1 days. Multiple linear regression analysis identified a significant correlation between presence of an abductor injury (beta = 0.8886; <i>p</i> < 0.0001), patient age (beta = -0.4452, <i>p</i> = 0.0083), and pre-revision head size (beta = 0.4082; <i>p</i> = 0.0172) with LOS (R<sup>2</sup> = 0.6351, <i>p</i> = 0.0002). Patients with abductor injury, larger femoral heads, and younger age are at risk for longer LOS.
