Brief Summary
Arthroscopic repairs of rotator cuff tears are now predominantly performed using double-row anchor and suture techniques. This approach is considered to have superior biomechanics compared to previous single-row repair techniques. Numerous double-row techniques with a knotted medial row have been described, but a consensus regarding their performance has yet to be established. One such technique is effective and easily reproducible: the "double-row Montgolfier" arthroscopic repair technique. This knotless approach features a uniformly distributed, load-sharing, and radially oriented suture configuration, much like the envelope cables of a Montgolfier hot air balloon, its namesake. Other advantages include the possibility of applying progressive manual tension to each suture and easy intraoperative adjustments based on the size, shape, and delamination of the tear, as well as the tension and quality of the tissues. Future studies are needed to validate the biomechanics and clinical outcomes of this technique. To date, only one publication describes this technique, from which its practice is gradually developing in France. No studies currently evaluate the performance of this approach. This pilot study will provide data to inform the design of other studies. The main objective of this study is to evaluate the clinical results (functional and pain) of the "Montgolfier Double-Row Knotless" technique at 12 months of follow-up.

Conditions
Outcome Measures
Primary Outcomes (1)
Achievement of the MCID (Minimal Clinically Important Difference) for the ASES (American Shoulder and Elbow Surgeons) score at 12 months.
For each patient, the change in the ASES score between day 0 and 12 months will be calculated. The patient will be considered successful if this change is greater than or equal to 27.1 (MCID of the ASES score).
between day 0 and 12 months
Study Arms (1)
Patient scheduled for rotator cuff repair using the Montgolfier double-row technique.
EXPERIMENTALInterventions
Rotator cuff repair using the Montgolfier double-row technique.
Ultrasound at 6 months and one year after surgery
Questionnaires : * American Shoulder and Elbow Surgeons (ASES), * Simple shoulder test (SST) * The Single Assessment Numeric Evaluation (SANE) * EVA pain score
