Summary
Experienced surgeons performing periacetabular osteotomy (PAO) have a low rate of major complications. Most complications are resolved without permanent disability, indicating PAO safety in expert hands.
Area of Science:
- Orthopedic surgery
- Hip preservation procedures
- Surgical outcomes research
Background:
- Periacetabular osteotomy (PAO) is a complex hip preservation surgery.
- Understanding PAO-associated complications is crucial for patient safety and surgical technique refinement.
Purpose of the Study:
- To prospectively identify and categorize all complications associated with periacetabular osteotomy.
- To evaluate the safety and complication profile of PAO when performed by experienced surgeons.
Main Methods:
- Prospective multicenter analysis of 205 unilateral PAOs performed by ten experienced surgeons.
- Standardized recording of perioperative complications at 10 weeks and 1 year post-surgery.
- Utilized a validated complication grading scheme for hip preservation procedures.
Main Results:
- Major complications (Grade III-IV) occurred in 5.9% of patients (12/205).
- Most major complications required revision surgery; thromboembolic events were managed medically.
- No vascular injuries, permanent nerve palsies, or acetabular osteonecrosis were reported.
Conclusions:
- Periacetabular osteotomy is a safe procedure for experienced surgeons, with a 5.9% rate of significant complications.
- The majority of identified complications did not result in permanent disability.
- This study provides valuable data on the complication profile of PAO beyond the learning curve.
