New trial from JNJ

Another new, unproven technique to rebuild cartilage is being tested. This one, called CAIS, uses a small piece (biopsy) of a patient's normal appearing cartilage and place it in a matrix- sort of like a jelly- then puts it back into the knee. The cartilage iis "minced" up during the procedure, but not expanded or grown. This is in contract to the ACI approach, which uses tissue culture as a means of expanding the cartilage. It is therefore less expensive. So far only a few patients have trialled this new procedure so it is far too early to tell about uts success.
