Platelet-rich fibrin matrix augmentation did not improve recovery and healing more than nonaugmented rotator cuff repair.

Patients: Eighty-eight patients (mean age, fifty-five years; 55% women) with a rotator cuff tear requiring surgical repair. Exclusion criteria were inflammatory joint disease, irreparable full-thickness tear, symptomatic arthritis of the acromioclavicular joint, rotator cuff arthropathy, pathologic abnormalities of the subscapularis tendon, Workers’ Compensation claims, or previous surgery on the affected shoulder. All patients had clinical follow-up, and seventy-eight patients (89%) had radiographic results.
