Summary

Suture-bridge technique has been widely used for rotator cuff tears with many studies showing superior clinical results and lower failure rates compared to other techniques. This study aims to compare clinical outcomes and radiological integrity of arthroscopic rotator cuff repair between knot-tying and knotless suture-bridge techniques. The possibility of tendon strangulation and necrosis at the medial row when performing a suture-bridge technique may lead to retear and structural failure. In order to avoid this complication, the knots used at the medial row and their tension might be a factor to consider. Our hypothesis is that a knotless suture-bridge technique might avoid tendon strangulation thus might have lower retear rates.

Conditions

  • Rotator Cuff Tears
  • Rotator Cuff Injuries

Interventions

PROCEDURE

Arthroscopic rotator cuff repair with knotless suture-bridge technique

A posterior portal will be established to obtain adequate visualization and an anterior portal will be established through rotator interval as a working portal for diagnostic arthroscopy and debridement. Then additional portals will be established and preperation of tendon will be performed and a burr will be used for footprint preperation. After determination of proper anchor locations, required number of suture anchors will be inserted just lateral to articular margin depending on the tear size. Then limbs of sutures will be passed from the rotator cuff and will be used to create a suture bridge over the tendon. Then these limbs will be loaded to anchors which will form the lateral row without tying the suture limbs at the medial row. These lateral anchors will be inserted to adequate location, just lateral and distal to greater tuberosity with adequate suture-bridge tension over the rotator cuff.

PROCEDURE

Arthroscopic rotator cuff repair with knot-tying suture-bridge technique

After the same preparation procedure as in knotless suture-bridge technique, required number of suture anchors will be inserted just lateral to articular margin depending on the tear size. Then limbs of sutures will be passed from the tendon and tied in a horizontal mattress suture pattern. After the establishment of medial row, suture limbs will be used to form a suture bridge over the tendon and will be loaded to lateral row anchors which then will be inserted lateral to greater tuberosity in a similar way to knotless repair technique.
