Surgical repair of massive or recurrent tears of the shoulder’s rotator cuff tendons can be improved with anabolic steroids, as per a research from the UNC’s School of Medicine.

The study was led by Dr. Spero Karas, assistant professor of orthopedic surgery in UNC’s School of Medicine and appeared in an issue of the American Journal of Sports Medicine.

Anabolic steroids benefit millions of people a year, said Karas, including those with deficiencies in sex hormones and burn victims who need to build up their metabolism to repair musculoskeletal tissue. They also are FDA-approved for treating anemia for their ability to help the body rebuild blood.

As it’s widely known that anabolic steroids can build muscle mass and strength, Karas said he thought these properties might apply to shoulder tissue and that Banes’ bioartificial tendon might provide the appropriate model for testing.

“In this new study, supraspinatus tendon cells were harvested from my patients during rotator cuff surgery, isolated and then sent to Albert’s lab,” Karas said. “The cells were then grown in his culture media to coalesce and form this experimental tendon model, the bioartificial tendon.”

It was further remarked by Karas that there were significant improvements in the biomechanical properties of the bioartificial tendon matrices when they were initially treated with anabolic steroid and then mechanical load or strain.
