Details and patient eligibility

About

The overall objective of this clinical investigation is to assess the safety and efficacy of full-thickness arthroscopic rotator cuff repairs augmented with the FiberLocker System for the subjects. The primary outcome of the investigation is to assess the safety after full-thickness arthroscopic rotator cuff repairs augmented with the FiberLocker System in terms of postoperative adverse events through the 12-month follow-up. Main secondary outcomes include measures of efficacy and clinical performance evaluated at 6-week, 4.5-month, and 12-month follow-ups including retear rate assessed using MRI and different functional performance scores.

  4. Previous enrolment into the current investigation,
  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
  9. Presence of an implanted metallic device or other implants that would contraindicate acquisition or inhibit radiologist review of an MRI of the index shoulder
  10. Pregnant or planning to become pregnant during the study period
  11. Breast feeding women
  12. Subject has conditions or circumstances that would interfere with study requirements.
  13. Contraindications and limitations of the MD as described in the IFUs.

  16. Complete full-thickness subscapularis tears greater than the superior 1/3 of the tendon, with Lafosse grade 3 or greater
  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

  26. Subjects with diabetes type I or II
  27. The subject currently has an acute infection in the area surrounding the surgical site
  28. Evidence of active infection, osteomyelitis, sepsis or distant infection which could spread to the index joint.
  29. Any comorbidity or condition that renders the patient a poor surgical candidate as determined by the Investigator.
