Autologous Chondrocyte Implantation

Autologous Chondrocyte Implantation (ACI) is a procedure used to repair damaged cartilage in joints, often the knee. It involves taking healthy cartilage cells (chondrocytes) from the patient's own body, usually from a non-weight-bearing area. These cells are then grown in a lab to increase their number. Once expanded, the cells are implanted back into the damaged area to promote new cartilage growth. This technique aims to restore joint function and reduce pain, helping patients return to normal activities. Because it uses the patient's own cells, the risk of rejection is minimized.
