For the repair of a cartilage defect in a human or animal patient, e.g. a
full thickness articular cartilage defect, use is made of an implant (1)
comprising an implant body (2) including a natural cartilage matrix and
being coated with cells having a chondrogenic potential, preferably
autologous cells. Preferably, the implant body consists of autologous
cartilage tissue with viable chondrocytes integrated therein which
cartilage tissue is produced by in vitro tissue culturing. Preferably,
the cells for producing the cartilage tissue and for coating the implant
body surfaces are the same. These cells are produced by in vitro cell
proliferation starting from chondrocytes isolated from a cartilage
biopsy. The chondrocytes which are de-differentiated during cell
proliferation are re-differentiated during tissue culturing and are in
particular suitable for producing and maintaining the cartilage matrix of
the implant body. The cells adhering to the surface of the implant body
are preferably also chondrocytes being de-differentiated by cell
proliferation, but not re-differentiated, and are therefore particularly
suitable for integrating the implant in the defect. Due to the cells
adhering to the surface of the implant body, the implant is successfully
integrated in the viable tissue surrounding the defect.
