An article published in the American Journal of Sports Medicine examines the risk factors for failed hip preservation surgery.
The researchers examined hip preservation procedures performed at the Hospital for Special Surgery Center for Hip Pain and Preservation. There were 147 patients who underwent pelvic procedures and were included in the study.
1. Intra-articular femoroacetabular impingement was the most common reason for revision procedures — occurring in 74.8 percent of the cases — and extra-articular impingement was the second most common in 9.5 percent of the cases.
2. Around 78 percent of the revision cases were addressed with arthroscopic surgery; however extra-articular impingement or residual acetabular dysplasia required open approaches.
3. The researchers found risk factors for revision procedures were:
• Female patients
• Younger patients
• Patients with worse preoperative outcome scores
4. Acetabular dysplasia and abnormal femoral version were not significantly different between the primary hip surgery group and the revision surgery group.
5. Among the revision hip surgery patients, the average short-term improvement in patient-reported outcomes occurred 15 months after their last revision procedure on average.
