Regrowing cartilage typically involves a procedure where cartilage-forming cells (chondrocytes) are harvested, multiplied in a lab, and then surgically implanted into the damaged area.
This process, often referred to as Autologous Chondrocyte Implantation (ACI), is a key method for cartilage regeneration. Here's a breakdown:
- Biopsy: A small sample of healthy cartilage is taken, often using a minimally invasive technique like a small-punch biopsy. This lessens the impact compared to more invasive arthroscopic procedures.
- Cell Culture: In a laboratory, the harvested chondrocytes are carefully cultured to increase their numbers. This multiplication step is crucial for generating enough cells to repair the cartilage defect.
- Implantation: The multiplied chondrocytes are then surgically implanted into the damaged area of the cartilage. These cells will then start to produce new cartilage matrix, filling in the defect over time.
Therefore, the process relies on using your own cells to rebuild the damaged cartilage, cultivated outside the body, and then re-introduced into the damaged site to promote regrowth.
