Arthroscopic Double-Layer Lasso Loop Technique to Repair Delaminated Rotator Cuff Tears

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Shoulder Arthroscopy

Background:

• Delaminated rotator cuff tears present a surgical challenge.
• Effective repair techniques are crucial for restoring shoulder function.

Purpose of the Study:

• To evaluate the efficacy of the arthroscopic double-layer lasso loop repair for delaminated posterosuperior rotator cuff tears.

Main Methods:

• Forty-one patients with delaminated posterosuperior rotator cuff tears underwent arthroscopic repair using the double-layer lasso loop technique.
• Clinical and functional scores were assessed preoperatively and postoperatively, with a minimum 2-year follow-up.

Main Results:

• Significant improvements were observed in Constant (54 to 83) and UCLA (6.4 to 9.5) scores (P < .001).
• Pain and strength improved across multiple functional tests (P < .001).
• A low rerupture rate of 3.1% was reported, with 15.6% partial ruptures.

Conclusions:

• The arthroscopic double-layer lasso loop technique is an effective treatment for delaminated posterosuperior rotator cuff tears.
• The procedure yields good to excellent functional recovery, pain relief, and patient satisfaction.
• Outcomes were comparable to the nonoperated side with a low rerupture incidence.
