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

Fig. 3

Femoral rotation (FR) angle and stem anteversion (SA) in revision and impingement distance. A External FR angle mean of 13.0° up to 56°. Among the 55 revision THA cases, 45 cases showed an external rotation, and 14 showed an external rotation of more than 30°. B External FR is correlated with functional SA in both revision and primary THA patients (r = 0.36, P < 0.01; Pearson’s correlation analysis). C, D External FR or functional SA was correlated with the impingement distance in revision THA patients (r = 0.30, 0.46, respectively; P < 0.01; Pearson’s correlation analysis)
