What is autologous cultured chondrocytes implant?
Autologous cultured chondrocytes are the patient’s own cartilage cells. The cells are removed from the patient and sent to a laboratory, where they are processed to increase their number. The cells are then implanted (placed) in the damaged part of the knee.
How long does autologous chondrocyte implantation last?
Conclusion: Autologous chondrocyte implantation has emerged as an effective and durable solution for the treatment of large full-thickness cartilage and osteochondral lesions of the knee joint. Our study suggests that the clinical and functional outcomes remain high even 10 to 20 years after the implantation.
What are bovine chondrocytes?
About Bovine Chondrocytes The cells are cryopreserved after isolation and can be cultured and propagated through several passages. Chondrocytes grown at low density will lose their phenotype and de-differentiate into fibroblast-like cells that produce type I collagen.
Is autologous chondrocyte implantation covered by insurance?
When Autologous Chondrocyte Implantation is covered Autologous chondrocyte implantation may be considered medically necessary for the treatment of disabling full thickness articular cartilage defects of the knee caused by acute or repetitive trauma, when all of the following criteria are met: 1.
How much is autologous chondrocyte implantation?
Autologous Chondrocyte Implantation is undoubtedly an expensive procedure but one of the best treatment options for joint diseases involving defective cartilage. It costs around $40,000, but this may vary depending on the country it is performed in.
What is chondrocyte tissue?
Chondrocytes. Chondrocytes are the only specialized cell type found in the cartilage tissue. Their diameters vary in between 7 and 30 µm according to the anatomical layer. These cells form 1–2% of the tissue volume (Alford and Cole, 2005). They are responsible for functional and structural integrity of cartilage.
What is autologous chondrocyte implantation knee?
Autologous chondrocyte implantation (ACI) is a relatively new, state-of-the-art procedure used to treat isolated full-thickness (down to bone) articular cartilage defects of the knee. It has been approved by the Food and Drug Administration for cartilage defects located at the end of the femur bone (thigh).
Is autologous chondrocyte implantation FDA approved?
The U.S. Food and Drug Administration today approved Maci (autologous cultured chondrocytes on porcine collagen membrane) for the repair of symptomatic, full-thickness cartilage defects of the knee in adult patients.
Do chondrocytes make cartilage?
Chondrocytes (/ˈkɒndrəsaɪt, -droʊ-/, from Greek χόνδρος, chondros = cartilage + κύτος, kytos = cell) are the only cells found in healthy cartilage. They produce and maintain the cartilaginous matrix, which consists mainly of collagen and proteoglycans….

What is autologous chondrocyte implants?
Autologous Chondrocyte Implantation. Autologous chondrocyte implantation (ACI) is a two-stage surgical procedure in which chondrocytes are harvested from a patient’s joint, expanded ex vivo, and re-implanted over an articular cartilage defect.
Are autologous chondrocytes regulated in the United States?
Use of autologous chondrocytes for patient care in the United States has been carefully regulated by the U.S. Food and Drug Administration (FDA, Biologics Division) and has required both Good Laboratory Practices (GLP standards) and Good Manufacturing Practices (GMP standards) since its introduction in the United States.
What is chondrocyte implantation?
Autologous Chondrocyte Implantation (ACI) Damage to joint (articular) cartilage (known as chondral lesions), or damage to both the cartilage and the underlying bone (known as osteochondral lesions), does not repair itself spontaneously and results in joint pain and poor function.
What is the success rate of autologous chondrocyte implantation?
Autologous Chondrocyte Implantation (ACI) Return to light sports activities is typically allowed at approximately 6 months with return to full sports activities between 9 and 12 months following the procedure based on the recovery. The overall success rate of ACI is approximately 85% in allowing patients to return to pain-free activities.
