To restore the elastic properties it is recommended to
mix chondrotissue with human serum before implantation.
For this purpose, about 9 ml blood should be drawn from
the patient before the arthroscopy. Then centrifuge the
blood 10 minutes or leave to stand at room temperature
for about 30 minutes until the blood clot has settled.
Microfracturing
After debridement, the defect should be measured and the
subchondral bone perforated with an awl at a distance
of about 3 -5 mm during arthroscopy.
Preparation of chondrotissue®
Cover chrondotissue® with the patient's own serum
(2 - 3 ml fluid is sufficient) and leave to stand for
about two minutes. This can be done directly in the supplied
steril container. The moistened chondrotissue can be cut
exactly to size to fit the defect.
Fixaction of chondrotissue®
chrondotissue®
can be fixed in the defect employing commonly used orthopaedic
fixation methods, e. g.:
• fibrin glue: Please apply the fibrin glue to the
edges of the chondrotissue® previously placed in the
defect and distribute it evenly
• bio-resorbable pins
• transosseous fixation
• cartilage suture
Rehabilitation
The information given below
is intended only as a guide and depends on the size and
the site of the defect, the patient's age and the general
demands of daily living.
Femoral and tibial defects
Patellar and trochlear defects
