Biceps Lasso Loop and Self- Locking Tenodesis Alongside Repair of Rotator Cuff Tears: Randomised Controlled Trial Study Protocol (BLAST 1)

The aim of this study is to compare the clinical results and complications of self-locking biceps tenodesis and double 360 lasso loop biceps tenodesis for the treatment of long chief of biceps or superior labrum anterior-posterior (SLAP) tendon pathology during shoulder arthroscopy in patients undergoing arthroscopic rotator cuff repair. Currently, there is no consensus on the use of tenodesis versus tenotomy to treat pathology of the long head of the biceps during arthroscopic rotator cuff repair. Numerous studies have examined the clinical results of long biceps tenotomy versus long biceps tenodesis, and there is no evidence to date of superiority of either technique. At Clinique Générale, we use a new, innovative technique called autobloc tenodesis to treat pathologies of the long head of the biceps. There are no comparative studies between autobloc tenodesis of the biceps and biceps tenodesis. Given its potential advantages, self-locking biceps tenodesis could emerge as the new technique of choice for treating biceps longus tendon pathology, potentially reducing differences in outcomes such as Popeye deformity. The information provided by this study could potentially guide future clinical practice, helping surgeons to choose the most appropriate treatment for their patients suffering from long biceps tendon pathology.
