Exactech, a developer and producer of implants, instrumentation, and smart technologies for joint replacement surgery, announced the successful first surgery using its new, advanced Activit-E polyethylene for the Truliant® knee replacement system.
Hany Bedair, M.D., performed the procedure at Massachusetts General Hospital (MGH) in Boston, where the material was developed by renowned polyethylene expert Orhun Muratoglu, Ph.D., director of the Harris Orthopaedic Laboratory at MGH. Dr. Muratoglu was also in attendance for the knee replacement case.
Activit-E offers a balance of material strength and toughness through chemically cross-linked polyethylene, while eliminating the need for gamma irradiation technology used in previous generations. It allows for active oxidative resistance and a long-term, high-performance polyethylene bearing, ultimately providing greater strength and active stabilization.
This new generation polyethylene is the latest innovation by Dr. Muratoglu and his team, including Ebru Oral, Ph.D., director of biomaterials research. Muratoglu invented the first crosslinked polyethylene, and the first of multiple generations of vitamin E, antioxidant polyethylene for leading orthopaedic companies.
