This study introduces a modified toggle suture technique for acetabular labral repair, improving labral inversion and stability. The method ensures proper labral contact with the femoral head for enhanced joint function.

Area of Science:

Orthopedic Surgery
Hip Arthroscopy
Biomedical Engineering

Background:

Acetabular labral tears disrupt hip joint stability and function.
Achieving an "in-round" repair that restores native labral position is challenging.
Maintaining the acetabular labrum's suction seal is crucial for joint health.

Purpose of the Study:

To present a modified toggle suture technique for acetabular labral repair.
To enhance labral inversion for more anatomic repair.
To offer a versatile and efficient surgical method.

Main Methods:

Utilizes an anchor-first approach with a modified toggle suture.
Accommodates various anchor types (all-suture, hard-anchor) and guide designs (straight, curved).

Incorporates a self-retaining hand-tied knot to prevent knot migration.

Main Results:

The technique facilitates enhanced labral inversion, aiding anatomic repair.
It offers vendor-agnostic flexibility and compatibility with diverse surgical tools.
The knot construct effectively prevents migration into the joint space.

Conclusions:

The modified toggle suture technique provides an efficient and adaptable method for acetabular labral repair.
This approach improves the ability to achieve an anatomic "in-round" repair.
It enhances surgical outcomes by ensuring labral stability and preventing complications.
