Description of intervention(s) / exposure
Treatment: Devices - Arthroscopic rotator cuff repair with REGENETEN™ Bioinductive Implant augmentation
Treatment: Surgery - Arthroscopic rotator cuff repair
Treatment: Devices - Arthroscopic rotator cuff repair for revision surgery

Experimental: ARCR augmented with REGENETEN™ Bioinductive Implant - During the ARCR procedure, the REGENETEN™ Bioinductive Implant is covering the tendon and attached to the bone and the tendon with small anchors.

Sham comparator: ARCR alone - The rotator cuff is repaired during arthroscopic standard procedure. No product is added for healing

Other: ARCR revision group - ARCR revision group allows treatment of subjects having recurrent tears, ARCR supplemented with REGENETEN


Treatment: Devices: Arthroscopic rotator cuff repair with REGENETEN™ Bioinductive Implant augmentation
The Arthroscopic rotator cuff repair aims at repairing the rotator cuff following tendon tear. The REGENETEN Bioinductive Implant is a medical device intended for the management and protection of tendon injuries. The REGENETEN Bioinductive Implant is indicated for the management and protection of rotator cuff tendon injuries in which there has been no substantial loss of tendon tissue. The REGENETEN Bioinductive Implant is a bioabsorbable implant device that provides a layer of collagen over injured tendons. The implant is designed to provide a layer of collagen between a flat tendon and the surrounding tissue. After hydration, the implant is an easy-to-handle, pliable, nonfriable, porous collagen sheet.

Treatment: Surgery: Arthroscopic rotator cuff repair
The Arthroscopic rotator cuff repair aims at repairing the rotator cuff following tendon tear without supplement.

Treatment: Devices: Arthroscopic rotator cuff repair for revision surgery
The Arthroscopic rotator cuff repair can also occur in recurrent tears. The REGENETEN Bioinductive Implant will be applied during the ARCR procedure.

Eligibility
Key inclusion criteria
1. Subject requires Arthroscopic rotator cuff repair (ARCR);
2. Subjects with a diagnosis of a symptomatic primary or recurrent (revision repair subject group), large or massive tear (= 3 cm AP/ML) of the supraspinatus and/or infraspinatus tendons amenable to repair. For screening purposes, a = 2 cm AP/ML tear as measured on MRI will be eligible to proceed to the operative visit but will have to be confirmed as = 3 cm on arthroscopy using a calibrated probe to proceed;
3. Subject is > 40 years of age (no upper limit);
4. Subject provides written informed consent for study participation using an Independent Ethical Committee (IEC) / Institutional Review Board (IRB) approved consent form;
5. Subject is willing and able to participate in required follow-up visits and is able to complete study activities.
Minimum age
40 Years
