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

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

- 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.)

- Isolated teres minor or subscapularis tears.

- Inelastic and immobile tendon which cannot be advanced to articular margin
