Why microfracture not good for OA!


Some orthopedic surgeons feel that you need to punch a lot of holes in order to get a good result.
One attempt to make new cartilage, particularly in younger individuals has been microfracture. This technique involves drilling holes and fracturing the subchondral bone multiple times. What occurs then is that fibrin clots form, blood vessels invade, and a few stem cells are recruited from the fractured bone marrow resulting in scar tissue that is biomechanically inferior to hyaline cartilage. As a result it wears away more quickly.
Microfracture, even in young people, is not the panacea it was once thought to be. Quite the opposite.
And for individuals with osteoarthritis, it definitely is not a therapeutic option.
