Patients will be randomized to receive HEALICOIL™ REGENESORB (the study anchor) or TWINFIX Ultra HA, a similar comparative product, for use in the repair of their shoulder injury. They will be asked to complete questionnaires throughout the study and will receive an MRI, CT and multiple ultrasound images. The MRIs and radiographs will be used to assess bony ingrowth at the repair site, and the ultrasound to assess repair success rate of the rotator cuff. The clinical and radiological outcomes will be compared between the study and control groups. It is hypothesized that there will be 85% high quality ossification at anchor site for HEALICOIL REGENESORB and 49.9% high quality ossification for TWINFIX Ultra HA at 24 months.

Ossification Quality Score (Bony Ingrowth Assessed Via CT)
The ossification quality score is an ordinal measure of quality of bone reabsorption that is divided into four progressive groups. Quality score 1 reflects "little or no bone ossification", Quality score 2 reflects "Some ossification; discontinuous or with a wide lucent rim", Quality score 3 reflects "Ossification with a thin lucent rim", and Quality score 4 reflects "Good ossification; border of tract vague". For this study, Quality scores 1 and 2 will be merged (defined as low quality ossification) as will Quality scores 3 and 4 (defined as high quality ossification). The proportion of suture anchors graded as having high quality ossification versus low quality ossification will be compared between the two groups to determine if there is a significant difference between Healicoil and Twinfix anchors in regards to quality of ossification.
Time frame: 2 years
Number of Participants With a Rotator Cuff Re-tear
Repair failure rate (Defined as number of subjects with a re-tear) determined by ultrasound 6 months after surgery.
Time frame: 6 months
Visual Analogue Pain Scale
The Visual Analogue Pain Scale (VAS) measures the patient-reported level of pain at the two-year follow-up. The scale runs from 0 to 10, with "0" indicating no pain and "10" indicating extreme pain. The lower the VAS Pain level, the better the outcome in regards to level of pain.
Time frame: 2 years
Function at Two Years as Measured by Western Ontario Rotator Cuff Index (WORC), PENN Shoulder Score (PENN), Single Assessment Numeric Evaluation (SANE), and EuroQol-5D (EQ-5D)
Outcomes at Two Years on the following: * Western Ontario Rotator Cuff Index (WORC): developed to help understand the particular signs, symptoms, and functional limitations associated with rotator cuff tendinopathy. The outcome is measured on a scale of 0 to 100, with 100 being the best outcome and 0 being the worst. * PENN Shoulder Score (PENN): The PENN is a 100-point shoulder-specific self-report questionnaire evaluating pain, satisfaction, and shoulder function. The outcome is measured on a scale of 0 to 100, with 100 being the best outcome and 0 being the worst. * Single Assessment Numeric Evaluation (SANE): A single question that asks "How would you rate your shoulder today as a percentage of normal (0% to 100% scale with 100% being normal)?" 0 indicates an abnormal shoulder, whereas 100% indicates a perfectly normal shoulder. * Euroqol-5D (EQ-5D): The EQ-5D is a patient-reported overall health questionnaire, with 100 indicating "The best health you can imagine" and
