Abstract

BACKGROUND:

The high failure rate after surgical repair of massive rotator cuff tears is a consistent problem.

PURPOSE:

To evaluate the clinical and radiological outcomes of arthroscopic rotator cuff repair with bone marrow stimulation and patch augmentation in patients with massive rotator cuff tears.

STUDY DESIGN:

Cohort study; Level of evidence, 3.

METHODS:

This study included 21 patients who underwent bone marrow stimulation and patch augmentation (group 1) and 54 patients who underwent conventional repair (group 2) for massive rotator cuff tears. Postoperative clinical outcomes were evaluated based on visual analog scale (VAS) for pain, simple shoulder test (SST), University of California, Los Angeles (UCLA), Constant, and American Shoulder and Elbow Surgeons (ASES) scores at baseline, 1 year postoperatively, and final follow-up. Anatomic outcomes were evaluated by using postoperative magnetic resonance imaging at 1 year after surgery.

RESULTS:

No significant differences in demographic characteristics and baseline data were observed between groups 1 and 2. Clinical symptoms were significantly improved at the final follow-up in both groups (P < .001). At the final follow-up, no significant differences were found in VAS pain (P = .676), SST (P = .598), UCLA (P = .100), Constant (P = .469), or ASES (P = .880) scores. However, the retear rate was lower in group 1 (4/21, 19.0%) than in group 2 (25/54, 46.3%) (P = .036), and the medial-row failure rate (type 2 retears) was much lower in group 1 (0/4, 0%) than in group 2 (18/25, 72.0%) (P = .014).

CONCLUSION:

Concomitant bone marrow stimulation and patch augmentation significantly reduced retear and medial-row failure rates in the arthroscopic repair of massive rotator cuff tears.
