About

Rotator cuff refers to a set of 4 shoulder tendons. These tendons are the sub-scapularis, supra-spinatus, infra-spinatus and teres minor. Rotator cuff tear corresponds to total or partial tendon disinsertion at the greater tuberosity level or a few centimeters in upstream. Rotator cuff surgery is an increasingly popular procedure practiced in France. In limited cuff lesions (distal or intermediates) and in absence of contraindication, absence of tendons' healing is around 10 to 20%. Sofcot estimates that 90% of caps' heals remain healed 10 years after surgery in distal lesions. However, even in case of a healed cuff, if tendon quality is not good, function will be impaired. Bioinductive implant Regeneten® is an advanced healing solution for biological improvement and regeneration of tendons on all types rotator cuff tear. A randomized study was initiated whose main objective was to evaluate integrity of repaired tendon with MRI one year after intervention according to Sugaya's classification. Results showed a recurrence rate of 8.3% in Regeneten® group compared to 25.8% in witness group. In this context, this study is based on hypothesis that adding Regeneten® during rotator cuff repair could be beneficial on tendon healing rate but also on tendon quality healing.

Full description

Rotator cuff refers to a set of 4 shoulder tendons. These tendons are the sub-scapularis, supra-spinatus, infra-spinatus and teres minor. They are located at the head of arm bone (humerus) and cover it, hence the name "cap". Shoulder tendon injuries occur following sport's trauma, microtraumas often falling within the framework of musculoskeletal disorders (MSD) and heavy professional practices, or they are more simply due to body natural aging. Rotator cuff tear corresponds to total or partial tendon disinsertion at the greater tuberosity level (part of humerus where the supraspinatus and infraspinatus tendons insert) or a few centimeters in upstream. This disinsertion creates a passage between glenohumeral joint and subacromial space. Subsequently, rupture can extend forwards or backwards (which is the most common frequent case). Rotator cuff surgery is an increasingly popular procedure practiced in France. Regardless of technical progress allowing today an ambulatory arthroscopic surgery, its success comes also from better knowledge of its indications and its clinical and histological results. Overall, in limited cuff lesions (distal or intermediates) and in absence of contraindication, absence of tendons' healing is around 10 to 20%. Sofcot estimates that 90% of caps' heals remain healed 10 years after surgery in distal lesions. However, even in case of a healed cuff, if tendon quality is not good, function will be impaired. Bioinductive implant Regeneten® is an advanced healing solution for biological improvement and regeneration of tendons on all types rotator cuff tear. A randomized study (NCT04444076) was initiated whose main objective was to evaluate integrity of repaired tendon with MRI one year after intervention according to Sugaya's classification. Results showed at one year follow-up a recurrence rate of 8.3% in Regeneten® group compared to 25.8% in witness group. In this context, this study is based on hypothesis that adding Regeneten® during rotator cuff repair could be beneficial on tendon healing rate but also on tendon quality healing.
