NEW YORK — Results presented at the American Shoulder and Elbow Surgeons Annual Meeting showed improved tendon quality at 1 year among patients who received bone marrow aspirate concentrate injection at the time of rotator cuff repair.

Brian J. Cole, MD, and colleagues randomly assigned patients with single tendon tears to receive either a bone marrow aspirate concentrate injection at the rotator cuff repair site after surgery or a sham incision at the iliac crest. Researchers assessed physical exam and patient-reported outcomes preoperatively and at 3 and 6 months and 1 year and 2 years postoperatively. At 1 year postoperatively, researchers performed MRI and graded in accordance with the Sugaya classification system.

“Essentially, all of our [patient-reported outcomes] PROs improved but the main ones, the ASES, improved in both groups but they were not different at the end points of follow-up,” Cole said in his presentation here.

Compared with the control group, Cole noted the bone marrow aspirate concentrate group had higher baseline simple shoulder test scores. He added simple shoulder test scores significantly improved in both groups at all time points.

“The mean Sugaya score was 3.5 [for the control group, and for the bone marrow concentrate] BMC group was 2.6,” Cole said. “Chi-squared analysis showed a strong association between the treatment with bone marrow concentrate vs. those that did not.” – by Casey Tingle
