Engineering Anisotropic Mechanical Properties in Large-Scale Fabricated Cartilage Constructs Using Microfiber Reinforcement.

ABSTRACT: Despite the growing prevalence of cartilage damage in the knee joint, effective regenerative treatments remain limited. One of the current challenges is the accurate matching of the local mechanical properties of the tissue, which vary throughout the articular joint surface. This study investigates the fabrication of cartilage constructs with anisotropic mechanical properties. Specifically, it aims to develop composite constructs by reinforcing gelatin-methacryloyl (gelMA) hydrogels with melt electrowritten (MEW) fibers arranged to mimic the surface anisotropic mechanical properties of the native articular cartilage. Large-size anisotropic MEW scaffolds are successfully generated, after which they are embedded in the hydrogel, yielding stable constructs. Local mechanical properties can be
