The Solution to Musculoskeletal Soft Tissue Injuries
About Us
Boylston Surgical was formed in 2024.
The original founding research and development company, Synthasome, spent 10 years perfecting this unique product family.
The focus was to bring novel innovations to tissue engineering and advanced solutions to orthopedic surgeries.
Our first product, BioTend, is a woven Poly-L-Lactic mesh for use in most major tendon and ligament surgical repairs and has FDA clearance for such procedures.
Its woven design mimics the mechanical properties of human tendons and ligaments, facilitating stronger, more functional, more resilient repairs.
The poly-l-lactic acid fibers slowly and safely absorb into the body over a period of 9-12 months, ensuring patients do not need follow-up surgeries to remove them.
After over 3,000 surgeries, BioTend has not had a single safety concern or negative reaction in a patient.
