In this case study, we examine how Atreon Orthopedics leveraged electrospinning technology to develop ROTIUM® Bioresorbable Wick — an advanced synthetic scaffold engineered to improve tendon-to-bone healing and support biologic tissue remodeling in orthopedic repair procedures.
Challenge
Rotator cuff repair remains challenging because the tendon-bone interface often does not provide an optimal biologic environment for healing. Atreon Orthopedics set out to address that gap with a solution that could support the healing cascade while integrating easily into standard surgical workflows.
Solution
Atreon Orthopedics developed ROTIUM® Bioresorbable Wick, an interpositional scaffold placed at the tendon-bone interface. The product is 100% synthetic and built with PGA and PLCL, and it is designed to supercharge the biologic environment, support tissue remodeling, and improve long-term outcomes after rotator cuff repair.
Using Fluidnatek electrospinning technology, Atreon can produce reproducible synthetic nanofiber scaffolds with the process control needed for development and manufacturing.
“We use the LE-500 system in the R&D and manufacturing of most of our products. I have over 20 years of electrospinning experience and am very pleased with the ease of use, consistency of product, and the manufacturing output of the LE-500 system. The high voltage and multiple voltage sources play a critical part in our manufacturing process. Our electrospun scaffolds have been used in over 20,000 surgeries to date and our fantastic outcomes for our patients are powered by the Fluidnatek systems.” — Jed Johnson, CTO of Atreon Orthopedics.
Results
ROTIUM has been used in more than 10,000 rotator cuff repair surgeries, and Atreon later received FDA 510(k) clearance to expand the indications to tendon repair surgeries.
Atreon reports that the scaffold supports repair at the critical tendon-bone interface and integrates seamlessly into standard surgical technique without adding surgical time.
The result is a clinically adopted bioresorbable scaffold platform that has helped Atreon broaden its regenerative orthopedic offering.
