Official title: Biceps Lasso Loop and Self- Locking Tenodesis Alongside Repair of Rotator Cuff Tears: Randomised Controlled Trial Study Protocol (BLAST 1)
Run by Clinique Générale dAnnecy · NCT06774820 · Data updated 2026-11-12
This study is testing two different surgical methods for treating a tendon in the shoulder during rotator cuff repair to see which one works better and has fewer complications.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients with a full-thickness rotator cuff tear of the supraspinatus or infraspinatus tendon.
✕Probably not a fit
Patients with partial or massive irreparable rotator cuff tears, or those with significant biceps tendon issues, may not benefit from this study.

What this trial studies
This study aims to compare the clinical outcomes and complications of two surgical techniques for treating the long head of the biceps tendon during arthroscopic rotator cuff repair. The techniques being evaluated are self-locking biceps tenodesis and double 360 lasso loop biceps tenodesis. The research addresses the lack of consensus on the best approach to manage biceps tendon pathology in conjunction with rotator cuff repairs. By utilizing innovative methods, the study seeks to determine if one technique offers superior results over the other.
Why it matters
Potential benefit: If successful, this study could lead to improved surgical outcomes and reduced complications for patients undergoing rotator cuff repair.
How similar studies have gone: While there have been numerous studies on biceps tenotomy versus tenodesis, this specific comparison of autobloc tenodesis against traditional methods is novel.

Show full inclusion / exclusion criteria
Inclusion Criteria: * Rotator cuff tear: confirmed preoperative diagnosis of a non- traumatic, full- thickness tear of the supraspinatus and/or infraspinatus and/or subscapularis tendon, as evidenced by ultrasound, arthro- CT or MRI. * Language proficiency: sufficient to allow for communication during the informed consent process and for the completion of the study questionnaires. Exclusion Criteria: * Tear type: partial thickness rotator cuff tears are excluded. * Tear severity: individuals with massive or irreparable rotator cuff tears are excluded. * Fatty degeneration: presence of rotator cuff muscle fatty degeneration classified as Grade 4 according to the Goutallier system will result in exclusion. * Glenohumeral osteoarthritis: patients exhibiting glenohumeral osteoarthritis, defined radiographically by the presence of joint space narrowing or osteophytes on anteroposterior (radiographs of the affected shoulder) will be excluded. * Prior shoulder surgery: history of previous surgical intervention on the affected shoulder will result in exclusion. * Popeye sign: preoperative presence of the Popeye sign will result in exclusion. * Cognitive impairment: pre- existing dementia or any condition that impairs the ability to understand study procedures and complete questionnaires and assessments is an exclusion criterion. * Pregnant, parturient or breast-feeding patients. * Persons under legal protection (curatorship, guardianship, safeguard of justice). * Persons deprived of their liberty by judicial or administrative measure * Persons under psychiatric care * Persons not affiliated to a social security scheme
