Title: What is the difference between OATS allo and auto
Post by: martialartist on December 15, 2010, 12:33:39 AM
My understanding of this is that with AUTO, a bone core with cartlidge on the end is taken from your knee and put in the defect.  The question now is with ALLO, is a core of bone with cartlidge on the end taken from a cadaver, or is it only the cartlidge taken, and no bone.  Anyone here know the answer?

It also appears that many/most people here are electing to have an autograft and not allo. I am wondering why this is. I am heavily leaning toward allo (or Denovo).


Thanks.

hey
I recently had an OATs surgery with an allorgraft. For me it was because the damaged area was so large, there was no way it was coming from my knee. And yes, the plug consisted of a section of bone with cartilage on the end.  The bad part on my knee was basically cut out and the cadaver plug was pressed into place. With an auto graft I dont think there is a waiting period. With the Allograft I had to go on a donor list and wait a couple months for them to find a match.
good luck
