biobrace® implant for arthroscopic repair of full thickness rotator cuff tears

Conditions: Rotator Cuff Tears

Summary: this study aims to evaluate the safety and effectiveness of arthroscopic rotator cuff repair augmented with the biobrace® implant vs. arthroscopic rotator cuff repair alone in subjects requiring surgical intervention for a full-thickness rotator cuff tear.

this is a prospective, single blind, multi-center, randomized, controlled, pivotal clinical study investigating the treatment of full thickness tears of the rotator cuff. tears must involve the supraspinatus and/or infraspinatus tendons and measure ≥ 2 cm and \< 5 cm. subjects meeting the inclusion/exclusion criteria will be enrolled and will undergo either arthroscopic rotator cuff repair augmented with the biobrace® implant or arthroscopic rotator cuff repair alone. clinical evaluations will be conducted at baseline (pre-operatively) and at 6 weeks, 3-, 6-, and 12-months post-operatively using various patient-reported outcome measures and mri to assess repair integrity and re-tear rate.

Eligibility criteria:
inclusion criteria: 1. male or female 40 to 70 years old 2. positive diagnostic imaging by mri within 6 months of enrollment of the index shoulder indicating a full thickness rotator cuff tear (rct): 1. tear of the supraspinatus and/or infraspinatus tendons 2. tear size ≥ 2 cm and \< 5 cm 3. chronic shoulder pain ≥ 3 months 4. failed non-operative treatment of the index shoulder to include one or all of the following: 1. oral analgesics 2. nonsteroidal anti-inflammatory medications (nsaids) 3. corticosteroid injections 4. activity modifications 5. physical therapy or home-guided exercises 5. able to read and understand the study reb/irb approved informed consent form (icf) 6. willing to be available to attend each protocol-required follow-up examination intraoperative inclusion criteria: 1. full thickness tear of the supraspinatus and/or infraspinatus tendons 2. tear size ≥ 2 cm and \< 5 cm 3. able to reapproximate the tendons to cover \> 50% of the footprint on the greater tuberosity exclusion criteria: 1. previous surgery of the index shoulder one year prior to the study surgery excluding diagnostic arthroscopy 2. fatty infiltration of the index shoulder rotator cuff muscle ≥ grade 3 (goutallier score) 3. major medical condition that could affect quality of life and influence the results of the study as determined by the investigator 4. oral steroid use or steroid injection within 6 weeks prior to surgery 5. active smoker 6. history of insulin-dependent diabetes 7. documented evidence of a history (e.g., liver testing) of drug/alcohol abuse within 12 months of enrollment 8. hypersensitivity to any investigational device materials including collagen of animal origin (bovine type-i), poly-l-lactic acid (plla) or polyethylene glycol (peg) 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. history of claustrophobia that would prevent an mri of the index shoulder 11. females of child-bearing potential who are either pregnant or breastfeeding or plan to become pregnant during the course of the study 12. currently participating, or plans to enroll in another clinical trial during this study that would affect the outcomes of this study as determined by the investigator 13. history of non-compliance with medical treatment or clinical trial participation 14. the subject is physically or mentally compromised (e.g., currently being treated for a psychiatric disorder, senile dementia, alzheimer's disease, etc.), to the extent that the investigator judges the subject to be unable or unlikely to remain compliant with protocol required follow-up 15. any comorbidity or condition that renders the patient a poor surgical candidate as determined by the investigator 16. the subject is receiving prescription narcotic pain medication 17. the subject currently has an acute infection in the area surrounding the surgical site 18. contralateral shoulder condition where rotator cuff repair is scheduled or to be scheduled over the course of this study 19. the subject's condition represents a worker's compensation case intraoperative exclusion criteria: 1. subject requires subscapularis repair other than a repair with a single anchor
