Intra-operative Inclusion Criteria

Subjects MUST meet the following criteria to be randomized in the study:

* Full thickness tear
* Tear size ≥ 5 cm in diameter

Exclusion Criteria:

Subjects will be excluded from the study, if they meet ANY of the following individual exclusion criteria:

* Known allergy to the device material (copolymer of PLA (poly (lactic acid) and -ε-caprolactone)
* Evidence of the following conditions:

  * Severe gleno-humeral or acromio-humeral arthritis
  * Full thickness cartilage loss as seen on MRI

  * Fully reparable rotator cuff tear \[Tear of less than 5 cm in diameter (or \< 4 cm2) with retractable tendon that can be fully repaired\]
  * Known neurovascular compromise
  * Complete deltoid muscle palsy
  * Traumatic muscle tears of the pectoralis or deltoid
* The subject requires concomitant:

  * Subscapularis repair
  * Labral repair of any type
  * Biceps tenodesis
* Previous surgery of the index shoulder in the past 1 year, excluding diagnostic arthroscopy
* The subject's condition is bilateral and rotator cuff repair is scheduled or to be scheduled over the course of this study for the contra lateral shoulder

* The subject is receiving prescription narcotic pain medication for conditions unrelated to the index shoulder condition
* The subject currently has an acute infection in the area surrounding the surgical site.
* Baseline WORC score less than 420

Intra-operative Exclusion Criteria:

Subjects will not be randomized and will be terminated from the study if they meet ANY of the following individual intra-operative exclusion criteria:

* Rotator cuff is/presents with:

  * Fully reparable with adequate tissue and muscle quality (equivalent to Goutallier stage 1 or 2)
  * Partial thickness tear of the supraspinatus
  * Evidence of significant osteoarthritis
* The subject requires concomitant:

  * Subscapularis repair
  * Labral repair of any type
  * Biceps tenodesis
