A new implant has been shown to induce new tissue growth in patients with partial-thickness rotator cuff tears, offering a potential alternative to traditional surgical repair.
Study results published in the current issue of Muscle, Ligaments and Tendons Journal demonstrate that a collagen-based bioinductive implant from medical device company Rotation Medical Inc induced significant new tissue formation in all study patients over a period of three months.
This tissue matured over time and became radiologically indistinguishable from the underlying tendon.
The study also assessed the ability of the implant to limit tear progression. Results showed that no tear progression was observed on MRI in any of the patients during the two-year post-operative period.
Additionally, all patients´ Constant and American Shoulder and Elbow Society clinical scores showed a considerable improvement.
“Partial-thickness rotator cuff tears frequently enlarge due to increased local strain and often progress to full-thickness tears,” commented Dr Desmond John Bokor, lead study investigator and associate professor in the Department of Orthopaedic Surgery at Macquarie University in Australia. “The results of this study demonstrate the ability of the bioinductive implant to induce new tendon-like tissue, enabling partial-thickness rotator cuff tears to decrease in size and in most cases disappear. The ability to heal partial-thickness rotator cuff defects, and thus prevent tear propagation and progressive tendon degeneration, represents a novel interventional treatment paradigm for these lesions.”
