Summary
Femoroacetabular impingement (FAI) is hip joint conflict from bone abnormalities. Surgical dislocation and morphology restoration improved patient function and pain, offering a joint-preserving solution for FAI.
Area of Science:
- Orthopedics
- Hip Surgery
- Biomechanical Analysis
Background:
- Femoroacetabular impingement (FAI) results from abnormal hip joint morphology causing painful motion.
- Joint-preserving procedures aim to restore normal anatomy and enable impingement-free movement.
Purpose of the Study:
- To evaluate the short-term functional and radiographic outcomes of treating FAI using surgical dislocation and offset restoration.
- To assess the efficacy of this joint-preserving technique in improving hip function and reducing pain.
Main Methods:
- Retrospective review of 46 patients (48 hips) with FAI.
- Surgical dislocation and restoration of proximal femur/acetabular morphology.
- Assessment using Merle D'Aubigné-Postel functional hip scores and radiographic analysis.
Main Results:
- Significant improvement in the average Merle D'Aubigné-Postel score from 13 preoperatively to 16.8 postoperatively.
- Positive functional outcomes observed in patients with limited radiographic signs of arthritis.
- Successful restoration of impingement-free motion was achieved.
Conclusions:
- Surgical dislocation with morphology restoration is an effective joint-preserving treatment for FAI.
- This approach improves symptoms and function in patients with impingement-related hip pain.
- It offers a viable option for managing FAI, particularly in those without advanced arthritis.
