"In-Round" Labral Repair After Acetabular Recession Using Intermittent Traction

Area of Science:

• Orthopedic Surgery
• Arthroscopic Techniques

Background:

• Hip arthroscopy for femoroacetabular impingement (FAI) relies on labral repair to restore the labral seal.
• Current techniques face challenges in assessing acetabular recession and labral repair congruity due to traction-induced femoral head distraction.
• Prolonged traction during hip arthroscopy poses a risk of nerve injury.

Purpose of the Study:

• To present a modified hip arthroscopy technique for acetabular recession and labral repair.
• To minimize traction time by strategically releasing traction during critical surgical steps.
• To improve the accuracy of labral repair and restore native hip biomechanics.

Main Methods:

• The described technique utilizes traction primarily for central compartment tasks.
• Traction is released to allow the femoral head to naturally seat the labrum against the acetabulum.
• This facilitates acetabular recession, anchor placement, and suture fixation with improved anatomical congruence.

Main Results:

• The technique prevents an "out-of-round" or everted labral repair.
• It allows for accurate assessment of acetabular recession and labral repair.
• Reduced traction time is achieved, potentially mitigating associated risks.

Conclusions:

• This modified technique effectively re-creates native hip anatomy and biomechanics after acetabular recession and labral repair.
• It offers a method to improve the quality of labral repairs in hip arthroscopy.
• Minimizing traction time enhances patient safety and surgical outcomes.
