title: MR arthrographic appearance of the postoperative acetabular labrum in patients with suspected recurrent labral tears.
abstract: OBJECTIVE
  The objective of our study was to evaluate the MR arthrographic appearance of the acetabular labrum in patients with a suspected recurrent acetabular labral tear after previous arthroscopic resection of a labral tear.
  
  
  CONCLUSIONS
  The labrum after excision will appear shortened on MR arthrography. A recurrent labral tear can be diagnosed by the identification on MR arthrography of a new line to the labral surface, an enlarged and distorted labrum, or a new paralabral cyst.
