or hylane cartilage is the smooth cartilage that covers the bone
in joints like the knee. Damage to articular cartilage has eluded
our ability to repair defects in it. Most defects in articular cartilage
occur through traumatic events, though there are many other causes.
Osteoarticular transfer system (OATS) is a surgical method of repairing
articular cartilage defects with hylane cartilage. Though OATS has
had early clinical success, long-term follow-up is essential for
a full evaluation of its effectiveness. Limitations of the technique
include the inability to deal with large and deep osteochondral
defects, limited availability and possible damage to donor sites,
non-filled spaces between the circular grafts and incomplete integration
of the donor and recipient cartilage.
