I was having very bad knee problems was hurting all the time could not bend down on my knee or keep it bent for very long I went to doctor Kirkland he said he could help me he sent me to have it MRI came back and he told me about PRP so I did everything you told me had to PRP done it was amazingly fast and no problems whatsoever within days of having it done absolutely no pain started getting better flexibility I can even get down on the floor and crawl on my knees with my grandson this has been amazing if I had to do it all over again I absolutely would and I would use doctor Kirkland,Dr Kirkland and his staff are great.
