Recently, Mayo Clinic researchers used 3D bioprinting to take on anterior cruciate ligament (ACL) reconstruction. The researchers designed a 3D printed bioabsorbable, porous scaffold to help with the reconstruction of ACL ligaments in the knee. But what's really special about this scaffold is that it's been developed in such a way as to deliver a bone-promoting protein, in order to improve bone regeneration, over an extended period of time. The recent Mayo Clinic study, published in a peer-reviewed journal, described the 3D printed scaffold's composition, and also compared various methods for delivering recombinant human bone morphogenetic protein 2 (rhBMP-2).
