How does autologous chondrocyte implantation work?
The chondrocytes that have been harvested and expanded are then injected underneath this patch where they adhere to the patient’s knee to form what is known as hyaline-like cartilage which resembles the native joint cartilage. Following implantation there is a period of restricted weight-bearing for up to 8 weeks.
Is autologous chondrocyte implantation successful?
Autologous chondrocyte implantation (ACI) for the treatment of articular cartilage lesions of the knee joint provides successful and durable long-term outcomes. The treatment of symptomatic cartilage defects is a challenging problem as injuries of the articular cartilage do not heal spontaneously.
How long does autologous chondrocyte implantation last?
This lasts for approximately 10–12 weeks. During these first 3 months, patients gradually increase the weight on their operated joint until full weight bearing is achieved. This is important for the proper nutrition of the cells.

What is a MACI implantation?
Matrix-induced autologous chondrocyte implantation or MACI is a procedure in which a patient’s own cells are used to regrow new cartilage for the knee joint. Because of this, it is a two-part procedure. At first, a cartilage biopsy is performed arthroscopically.
Is the MACI procedure painful?
Dr. The new implant is adhered using a fibrin sealant. Better, pain free, functional movement is expected 6 months later – shown in a trial conducted by SUMMIT. MACI® can be used for cartilaginous defects of any shape and size, are more flexible, with less feeling that a foreign object was placed in the knee.
Are micro fractures painful?
Some patients may develop mild transient pain, most frequently after microfracture has been performed on the patella (kneecap) and trochlear groove (the groove on the femur in which the patella glides during motion).
