Rotator Cuff Repair Using Standard Double Row Technique With Platelet Rich Fibrin Membrane vs. Standard Double Row Technique (RCRPRFM)

Inclusion Criteria:

• Evidence of a rotator cuff tear as determined by clinical examination and diagnostic imaging (MRI)
• Patient undergoes arthroscopic rotator cuff repair
• Age 18 or older

Exclusion Criteria:

Pre-operative exclusion criteria

• Patient has had a previous arthroscopic rotator cut repair
• A previous diagnosis of Rheumatoid Arthritis
• Evidence of major joint trauma, infection, avascular necrosis, chronic dislocation, inflammatory or degenerative glenohumeral arthropathy, frozen shoulder, or previous surgery of the affected shoulder,
• Evidence of significant rotator cuff arthropathy with superior humeral translation and acromial erosion diagnosed by x-ray or other investigations,
• Medical device that would exclude the patient from having a MRI, including a pacemaker, cardiac defibrillator, aneurysm clips, carotid artery clamp, neurostimulator, insulin or infusion pump, implanted drug infusion device, bone growth/fusion stimulator, or ear implant.
• Major medical illness (life expectancy less then 2 years or unacceptably high operative risk),
• Inability to speak or read English
• Psychiatric illness that precludes informed consent.
• Pregnant patients.
• Age 17 or younger
• Unwillingness to be followed for 2 years.
• Bilateral Rotator cuff tear confirmed by clinical exam and MRI
• Patients enrolled in the study who demonstrate retear on clinical exam and MRI, then elect for a repeat surgery.

Intra-operative exclusion criteria (Note: This information will be collected during the chart audit and patients will be excluded from the study at that time.)

• Irreparable cuff tears or tears extending into the subscapularis or teres minor
• Isolated teres minor or subscapularis tears.
• Inelastic and immobile tendon which cannot be advanced to articular margin
