non-weight bearing area of the joint. The<br />
cells are subsequently transported to a cell<br />
expansion laboratory and, after 9 weeks,<br />
the expanded cells are sent back to the<br />
surgeon for re-implantation in the patient.<br />
In conventional ACI, the cells are implanted<br />
underneath a periosteal flap, which has<br />
been harvested from the patient’s tibia and<br />
sewn onto the cartilage defect, or by using a<br />
biodegradable membrane or matrix in which<br />
the cells are seeded.<br />
ChondroCelect<br />
ChondroCelect is a characterized cellbased<br />
medicinal product, used in an<br />
ACI procedure, in which the cell culture<br />
methods have been specifically developed<br />
to maintain the phenotypical stability<br />
of the cells to promote the formation of<br />
stable hyaline-like articular cartilage. The<br />
procedure whereby characterized cells<br />
are implanted is called ‘Characterized<br />
Chondrocyte Implantation’ (CCI).<br />
ChondroCelect has been validated in a<br />
prospective, controlled randomized clinical<br />
trial and can be used in combination<br />
with an easy-to-use collagen membrane.<br />
Moreover, 370 patients, presenting a wide<br />
variety of lesions, have been treated in a<br />
compassionate use program 4 .<br />
