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.

---|---|---|---|---|
Primary | Sugaya classification of rotator cuff integrity | This is a classification system described by Sugaya et al. which uses magnetic resonance imaging in order to evaluate tendon integrity after rotator cuff repair. Postoperative cuff integrity is classified into 5 categories: type I, sufficient thickness with homogenously low intensity; type II, sufficient thickness with partial high intensity; type III, insufficient thickness without discontinuity; type IV, presence of minor discontinuity; type V, presence of major discontinuity | 6 months postoperatively | |
Primary | Constant shoulder score | This is a clinical functional assessment test used for shoulder disorders. The score consists of 4 sections: pain, activities of daily living, mobility and strength. | Change from baseline Constant shoulder score at 12 months | |
Secondary | Shoulder range of motion | Shoulder abduction, forward flexion, external rotation, internal rotation and extension degrees measured by a goniometer | Change from baseline range of motion at 12 months | |
Secondary | Visual analog scale for pain | A visual scale which classifies the intensity of pain between 0-10. | Change from baseline visual analog scale for pain at 12 months | |
Secondary | Retear patterns of rotator cuff tendons | Retear patterns of rotator cuff tendons will be evaluated by using postoperative magnetic resonance images. Detected retears will be classified as type 1 (lateral) or type 2 (medial/musculotendinous) rotator cuff retears/failures. | 6 months postoperatively |
