Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

• Constant score (CMS)

  The CMS is a 100-point scale comprising four components, including a patient-reported section (pain 15 points and activity level 20 points), for a total of 35 points. Alongside this, there is a doctor-reported section (shoulder strength 25 points, range of motion 40 points) for a total of 65 points.

  1 year after surgery

Secondary Outcomes (1)

• American Shoulder and Elbow Surgeons Score

  3 months, 6 months, 1 year after surgery

ACTIVE COMPARATOR

Procedure: arthroscopic tenodesis

Interventions

self-blocking tenodesis PROCEDURE

the LHB tendon is detached from its origin in the superior labrum. This technique supports the self-locking mechanism of the LHB tendon in the bicipital groove by detaching the tendon from the Y-shaped superior glenoid, including the superior labrum. A radiographically visible suture will be attached to the proximal part of the LHB tendon to facilitate later localization of the LHB tendon during imaging (3-0 stainless steel, ethicon).

self-blocking tenodesis

arthroscopic tenodesis PROCEDURE

LHB tendon is detached from its origin, and sutured. Next, the LHB tendon is fixed in the bicipital groove using a 360-lasso loop tenodesis technique. A radiographically visible suture will be attached to the proximal part of the LHB tendon to facilitate subsequent localization of the LHB tendon during imaging (3-0 stainless steel, ethicon).
