Summary

The purpose of this study is to compare a novel, cost-effective arthroscopic trans-osseous rotator cuff repair technique, known as the 'Grand-Knot' technique, against the standard repair using all-suture anchors. The study evaluates which method provides better functional recovery and structural healing for patients with full-thickness supraspinatus tears. Patients were randomized to receive either the Grand-Knot repair or the standard anchor repair and were followed for a minimum of 2.5 years to assess shoulder function using the ASES score, range of motion, and tendon integrity."

Conditions

  • Rotator Cuff Tear

Interventions

PROCEDURE

Grand-Knot Technique

Use of a Giant-needle to create trans-osseous tunnels and securing the tendon with a specialized suture-block (Grand-Knot).

DEVICE

All-Suture Anchors (Y-Knot RC)

Standard repair using 2.8 mm all-suture anchors placed in the humeral footprint.
