What is a MACI procedure?
The MACI® Procedure (autologous cultured chondrocytes on porcine collagen membrane) is a specialized procedure for the treatment of the knees. It is a surgical option indicated for cartilage defects in the knee. When more conservative interventions such as physical therapy or steroid injections have failed to relieve pain, the procedure allows the surgeon to implant the patient’s own normal articular cartilage. It is completed by harvesting a collection of the patient’s own (autologous) healthy cartilage taken from a non-weight bearing position. This autologous cartilage contains chondrocyte cells which are considered to be the building blocks of cartilage. These cells are then placed onto a membrane of collagen which encourages expansion of these cells, and in turn, new healthy cartilage. Your surgeon will most likely remove the area of damaged tissue on the affected knee. Next, the MACI® implant will be surgically placed at the location of cartilage damage and absorbed back into your own tissue. Multiple MACI® implants may be used at one time.
