Key Points of Acetabular Rim Resection

Use preoperative radiographic planning to determine the depth of the bony resection required to eliminate the crossover sign.

Obtain adequate exposure through an inter-portal capsulotomy, followed by capsular elevation away from the labral edge.

Remove all soft tissue from the acetabular rim using an ArthroCare RF wand.

Confirm the position and extent of the pincer lesion using fluoroscopy.

Detach the labrum to expose all areas of tearing and articular cartilage delamination.

Resect the pincer lesion using a hip-specific, 5.5-mm burr.

Use fluoroscopy to verify that an adequate resection has been performed.

Recognize and resect a prominent AIIS.

Remove any excess articular cartilage back to a stable bone-cartilage interface.
