3D-Printed Bioabsorbable Scaffold for ACL Reconstruction with Extended Release of Bone-inducing Growth Factor Described in Tissue Engineering
New Rochelle, NY, February 27, 2017—Researchers have designed a 3D-printed porous scaffold for use in reconstructing ruptured anterior cruciate ligaments (ACL) in the knee and engineered it to deliver a human bone-promoting protein over an extended period of time to improve bone regeneration. A study describing the composition of the scaffold and comparing different delivery methods for recombinant human bone morphogenetic protein 2 (rhBMP-2) is published in Tissue Engineering, Part A, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Tissue Engineering website until March 27, 2017.
Joshua Alan Parry, MD, Sanjeev Kakar, MD, and coauthors from Mayo Clinic, Rochester, MN, demonstrated the strength of the scaffold in a rabbit ACL reconstruction model. In the article entitled "Three-Dimension-Printed Porous Poly(Propylene Fumarate) Scaffolds with Delayed rhBMP-2 Release for Anterior Cruciate Ligament Graft Fixation," the researchers compared the use of four approaches, including microspheres, to reduce the initial burst release of rhBMP-2 from the scaffold and extend its release over time.
"This work is a good example of the fusion of technologies -- controlled release drug delivery and 3D printing," says Tissue Engineering Co-Editor-in-Chief Peter C. Johnson, MD, Principal, MedSurgPI, LLC and President and CEO, Scintellix, LLC, Raleigh, NC.
