From: Postoperative excessive external femoral rotation in revision total hip arthroplasty is associated with muscle weakness in iliopsoas and gluteus medius and risk for hip dislocation

Patient and surgical factors associated with external rotation of the femur. A 2-stage revision total hip arthroplasty had higher external FR than 1-stage revision total hip arthroplasty (mean 17.2 ± 12.7° vs. 10.1 ± 12.0°; P = 0.03). B–D CT densities for the psoas and gluteus medius muscles, and anatomical stem anteversion were negatively correlated with the external rotation of the femur (R = 0.34, 0.42, and 0.54, respectively; P < 0.01; Pearson’s correlation analysis)
