Arthroscopic Double-Row Rotator Cuff Repair With Box Configuration

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomedical Engineering

Background:

• Arthroscopic transosseous-equivalent (TOE) techniques offer advantages for rotator cuff tears (RCTs).
• These methods may provide a more efficient surgery with a self-reinforcing construct.
• Clinical results are comparable to traditional medial knotted TOE repair.

Purpose of the Study:

• To describe a modified arthroscopic knotless double-row (DR) rotator cuff repair (RCR) technique.
• This technique addresses small-to-moderate full-thickness RCTs unsuitable for standard anchors.
• The goal is to achieve anatomical compression and secure fixation.

Main Methods:

• A modified arthroscopic DR RCR technique using knotless fixation is detailed.
• The procedure involves specific portal creation and placement of 2.6-mm FiberTak RC anchors medially.
• A double pulley technique and lateral row anchors create a TOE box configuration for compression and footprint restoration.

Main Results:

• The modified technique allows for anatomical compression of the rotator cuff tendon.
• Medial compression is enhanced by the box configuration.
• Knotless fixation is utilized for improved surgical efficiency.

Conclusions:

• A modified arthroscopic DR RCR with box configuration is an effective treatment for small-to-moderate full-thickness RCTs.
• This technique provides anatomical compression and secure fixation.
• It is a viable option for patients failing conservative management.
