Erratum to: Clin Orthop Relat Res DOI 10.1007/s11999-016-5040-8 In the study, ‘‘What MRI Findings Predict Failure 10 Years After Surgery for Femoroacetabular Impingement?’’ the overview of the study population in Fig. 1 is incorrect as published. A total of 20 hips underwent MRA at another institution, not eight hips. Additionally, 10 hips had been operated on the contralateral side with a similar appearance, not 22 hips. The corrected Fig. 1 is shown in this erratum. We apologize for the error.
