Comparison of Two Arthroscopic Rotator Cuff Repair Techniques: Knot-tying Versus 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."

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.
