Rotator cuff repair using a FiberLocker patch to reinforce the tendon

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults aged 40–65 who require primary arthroscopic repair of traumatic full‑thickness supraspinatus or combined supraspinatus‑infraspinatus tears will receive augmentation with the FiberLocker System (SpeedPatch PET and FiberLocker instrument). The primary focus is safety, recording postoperative adverse events through a 12‑month follow‑up. Efficacy and clinical performance will be measured at 6 weeks, 4.5 months, and 12 months, including MRI assessment of retear rate and standard shoulder function scores. All procedures and follow‑up visits are conducted at Balgrist University Hospital in Zurich.

5. Enrolment of the PI, his/her family members, employees and other dependent persons,
6. Inability to follow the procedures of the investigation, or known or suspected non-compliance, e.g. due to language problems, psychological disorders, dementia, drug or alcohol abuse, etc. of the subject
7. Active smoker
8. History of claustrophobia that would prevent an MRI of the index shoulder

17. Massive rotator cuff tears, tear size equal to or greater than 4 cm in the anterior-posterior dimension or irreparable rotator cuff tear
18. Limited space or exposure for implant delivery
19. Structural or pathological condition of the bone or soft tissue that could impair healing.
20. Intraoperative rotator cuff tear characteristics differ from preoperatively expected characteristics and fulfil one of the abovementioned criteria
21. Fatty infiltration of the index shoulder rotator cuff muscle \> Goutallier Score 2
22. Corticosteroid injection in the operative shoulder within 6 weeks of operation
23. Subject shows frozen shoulder/adhesive capsulitis at day of surgery
