New study shows 96% healing of hard to treat large and massive rotator cuff tears with Smith & Nephew's REGENETEN(TM) Bioinductive Implant

LONDON, Nov. 19, 2019 -- (Healthcare Sales & Marketing Network) -- Smith & Nephew (LSE: SN,NYSE: SNN), the global medical technology business, today announces a new clinical study illustrating the successful treatment of large (3-5cm) and massive (5cm+) rotator cuff tears using its REGENETEN Bioinductive Implant.1

Repairs of large and massive rotator cuff tears are recognised as having a high rate of failure, with more than 40% requiring further treatment2-4. The prospective, non-comparative arm study of the REGENETEN implant in 23 patients with large and massive tears in the US, published in the American Journal of Sports Medicine, demonstrated a 96% tendon healing rate at two years. There was no significant difference in treatment success between primary repairs and revision surgery.

"This study provides further insight into the success of the REGENETEN Bioinductive Implant," said Michael O'Brien MD, Associate Professor of Clinical Orthopaedics, Tulane University School of Medicine, New Orleans, LA. "It is the latest addition to the growing body of evidence supporting REGENETEN as an effective treatment option that now covers the entire spectrum of tears from partial to large and massive tears."

The collagen-based REGENETEN Bioinductive Implant stimulates the body's natural healing response by inducing the growth of new tendon-like tissue to biologically augment the existing tendon and disrupt disease progression5-7. The REGENETEN implant, delivered arthroscopically through a small incision over the location of the rotator cuff tendon injury, is about the size of a postage stamp and is gradually absorbed within 6 months.7*

Tendon healing was assessed by serial ultrasound examinations to 24 months and a single post-operative MRI. Tendon thickness increased from 3 months to 12 months before slightly decreasing at 24 months, representing functional remodelling of the new tissue. No implant-related adverse events occurred.1

The REGENETEN implant's efficacy in patients with partial-thickness and small full-thickness tears is well-known with data showing rapid and sustained healing including a reduced tear size in 94% of partial-thickness tear patients5 and no re-tears at 24 months in small full-thickness tears.8

"REGENETEN is the first solution of its kind to treat large and massive thickness rotator cuff tears," said Vasant Padmanabhan, President of R&D, Smith & Nephew. "More than 650,000 rotator cuff procedures take place annually in the US, potentially growing at a rate of 5-6% each year. This data reinforces our confidence that this revolutionary technology is truly a game-changer in the treatment of patients with rotator cuff disease."

The REGENETEN Bioinductive Implant is currently available in the United States.
