Cartilage regeneration via autologous chondrocyte implantation on biocompatible scaffold

"Cartilage regeneration via autologous chondrocyte implantation on biocompatible scaffold" refers to a surgical technology used to repair focal defects in articular cartilage, especially of the knee. In this procedure, a patient’s own cartilage cells (chondrocytes) are harvested, expanded in vitro, and implanted into the cartilage defect, often using a biocompatible scaffold to enhance cell retention and support cartilage regeneration. There are several generations of this technique, including matrix-induced autologous chondrocyte implantation (MACI), which uses a collagen or synthetic matrix to deliver the cells. The primary goal is to generate new hyaline-like cartilage to restore function and decrease symptoms in people with isolated cartilage injuries[1][3][6][9]. While not a molecular target itself, the procedure acts on cartilage through biological repair and cellular proliferation.
