OUTCOMES OF ARTHROSCOPIC SURGERY FOR TREATMENT OF ROTATOR CUFF TEARS USING KNOTLESS DOUBLE ROW TECHNIQUE
Main Article Content
Abstract
Background: Arthroscopic rotator cuff repair has continuously evolved, from single-row to double-row and knotless transosseous-equivalent techniques. Among these, knotless double-row repair has been highly regarded worldwide due to its biomechanical advantages and improved tendon healing outcomes. Yet, in Vietnam, evidence on the effectiveness of this method remains limited. Objective: To evaluate the clinical and imaging outcomes after arthroscopic knotless double-row rotator cuff repair. Methods: A descriptive study combining retrospective and prospective data was conducted on 40 patients with rotator cuff tears who underwent arthroscopic knotless double-row repair at Vinmec Healthcare System between January 2023 and June 2025. Results: The UCLA score improved from 20.45 ± 1.62 to 32.78 ± 1.69 (p<0.01), and the ASES score increased from 27.56 ± 2.16 to 94.48 ± 3.73 (p<0.01). Among 36 patients who underwent MRI at 6 months postoperatively, the rate of complete or near-complete tendon healing (Sugaya I–II) was 83.3% (I: 38.9%; II: 44.4%); Sugaya III accounted for 13.9%, Sugaya IV 2.8%, and no Sugaya V was observed. Four patients assessed by ultrasound all demonstrated grade 2 tendon healing. No patients were classified as “poor” according to UCLA at the final follow-up. Conclusion: Arthroscopic knotless double-row rotator cuff repair provides significant functional improvement, with a high tendon healing rate and there was only 1 case of grade IV re-tear according to Sugaya but the function of this case was still good so no need for re-surgery. This technique can be widely applied in Vietnam.
