Autologous chondrocytes are seeded in a
bovine-derived three-dimensional type I
collagen honeycomb matrix
The chondrocyte-embedded matrix is then
cultured in a bioreactor, which creates an
environment of variable hydrostatic pressure
and low oxygen tension, to simulate intra-
articular conditions
NOVOCART™3D is a combination of
autologous chondrocytes and a biphasic,
three-dimensional collagen-chondroitin
sulphate scaffold
Cultured Cells embedded into the scaffold
Matrix: three-dimensional, biphasic collagen-
chondroitin sulphate scaffold.
Cultivation time: 2-3 weeks from cartilage
harvest
MACI, autologous cultured chondrocytes on
porcine collagen membrane, is a cellular
sheet that consists of autologous
chondrocytes seeded on a 3 x 5 cm,
resorbable porcine Type I/III collagen
membrane, for implantation into cartilage
defects of the knee. The active ingredients
of MACI are the autologous cultured
chondrocytes and porcine Type I/III
collagen.

EVALUATION & TREATMENT OF THE INJURED ATHLETEADVANCED TOPICS IN SURGERY AND REHABILITATION
Reconstruction Summary• Background factors critical-
• Alignment, tracking, stability, meniscus
• MACI technically much easier to perform, less invasive, more uniform cell ditribution
• Realistic patient Informed consent –risks and recovery
• Surgeon knowledge of outcomes and skill factor
