Foreman SC, Zhang AL, Neumann J, et al. - Forty-two individuals (43 hips) who were scheduled for femoroacetabular impingement surgery were prospectively recruited in order to define postoperative MRI findings following femoroacetabular impingement surgery in relationship with pain variations and surgical findings. MR images were assesed for the presence of acetabuloplasty or femoroplasty, presence of chondral and labral repair surgery, bone marrow edema, subchondral cysts, chondral defects, labral tears, capsular defects, and effusion. For femoroacetabular impingement, compared with other aspects of surgical correction, a greater correlation with postoperative pain was exhibited by arthroscopic acetabuloplasty. Moreover, femoroplasty and labral repair were reliably diagnosed on 3-T MRI, although, in the assessment of acetabular chondral repair, limitations were noted.
