Clinical Experience and New Developments
Single
10 mm graft after 3 years
(Vladimir Bobic, 1996)
Though
transplantation of autogenic (from yourself) osteochondral grafts
has a history dating back to the late 1970's, the specific technique
called "OATS" or "mosaicplasty"was first
reported in the early 1990's. The results have been quite favorable
in terms of pain relief and the ability to transplant and maintain
the hylane type cartilage. In 1996 and 1997, Hangody et al.
published the animal trials and their extensive clinical experience
(over 370 procedures) demonstrating the medium term (longest-6
years) survival of the hylane articular cartilage. As for new
developments, larger harvesters (10-14mm) have been developed
to fill larger defects with one harvest. Filling donor defects
with hydroxyapatite (HA) rods, bioactive growth factors to enhance
integration of the hylane cartilage and biological glues to
seal the cartilage interfaces have all been on the forefront
of the OATS development.
