Revision FAI surgery

Abstract

Revision hip preservation for failed FAI surgery will play a growing role as the numbers of primary procedures increase. Effective treatment requires diagnosing the cause of failure and formulating an appropriate treatment plan that considers all potential diagnoses and treats the cause of failure, lest the same mistake be made again. The most commonly reported reason for revision is under-resection of the impinging bone; however, bony over-resection, extra-articular impingement, joint instability, labral insufficiency, and heterotopic ossification may also necessitate revision procedures. Outcomes typically improve after revision surgery, but are inferior to the results seen with primary procedures. Patients with extensive cartilage damage do not predictably improve with further preservation attempts and may be candidates for hip arthroplasty.
