Citrelock® Differentiated Biomaterial and Design Features

ALLENDALE, N.J., June 29, 2023 (GLOBE NEWSWIRE) — Acuitive Technologies, Inc. (Acuitive) today announced the first surgical use of its Citrelock® ACL Tendon Fixation Device. The new ACL device provides surgeons a differentiated design via a tendon-friendly spiral thread featuring a next-generation resorbable technology, known as Citregen, that has unique molecular and mechanical properties for orthopedic surgical applications.

Robin Gehrmann M.D., President of the New Jersey Orthopedic Society and Clinical Assistant Professor of Orthopedics, Rutgers-New Jersey Medical School, successfully implanted the first Citrelock ACL Tendon Fixation Device today.

“By leveraging Citregen’s unique material properties, the Citrelock Tendon Fixation Device introduces design features to ease insertion and secure fixation without damaging the tendon during placement,” said Robin Gehrmann, MD, orthopedic surgeon. “It has been exciting to participate in the development of a completely novel biomaterial for use in orthopedic applications. I believe this unique material technology will improve tendon fixation as it participates in the natural healing process while avoiding chronic inflammation seen with other biodegradable devices.”

CITRELOCK ACL Tendon Fixation Device

The Citrelock ACL Tendon Fixation Device offers surgeons:

  • Biomimetic material composition to match the native bone inorganic content
  • A novel soft spiral thread design to avoid tendon laceration
  • A compressive strength similar to cortical bone and a modulus similar to trabecular bone
  • Elastomeric properties for improved pull-out strength
  • A controlled resorption rate to mitigate chronic inflammation

“Our customers are looking for a more predictable and effective bioresorbable material than what is currently on the market,” said Rui Ferreira, VP of Product Development, Acuitive. “The Citrelock ACL Tendon Fixation Device helps fill that clinical need with its innovative material technology and unique design. Citrelock ACL System is an exciting addition to Acuitive’s portfolio and is the first in a series of new products we will be launching with a focus on the Sports Medicine market.”
