Summary
This study presents a novel acetabuloplasty technique for femoral acetabular impingement (FAI) that preserves the chondrolabral junction. This method avoids labral detachment, potentially improving healing and preserving vascular supply during FAI surgery.
Area of Science:
- Orthopedic Surgery
- Hip Arthroscopy
- Biomechanical Engineering
Background:
- Femoral acetabular impingement (FAI) involves cam and pincer lesions, which can lead to labral tears and osteoarthritis.
- Previous acetabuloplasty techniques often detach the labrum, potentially compromising its healing and blood supply.
Purpose of the Study:
- To present a modified acetabuloplasty technique that maintains the chondrolabral junction during surgical correction of FAI.
- To evaluate the feasibility and advantages of preserving the labrum's contiguous transition zone with the acetabulum.
Main Methods:
- A subperiosteal elevation of the labrum/chondral complex off the acetabular rim.
- Contouring of the acetabular shelf using fluoroscopic guidance and intermittent traction.
- Repair of the elevated labrum using vertical mattress stitches.
Main Results:
- The technique allows for effective contouring of pincer deformities in FAI.
- It avoids surgical detachment of the labrum at the chondrolabral junction.
- Preservation of the contiguous transition zone between the acetabulum and labrum is achieved.
Conclusions:
- This acetabuloplasty technique offers a method to address FAI bone morphology while preserving the integrity of the chondrolabral junction.
- Maintaining the chondrolabral junction may offer advantages in labral healing and vascularity compared to traditional detachment methods.
