BLOODCURE thinks it is safe to assume that both of them have some arthritic changes in their knees. This means that they have lost some of both the smooth cartilage covering the bone (articular cartilage) and some of the cushioning cartilage between the thigh and shin bones (meniscus cartilage). In Tiger's case, he may have been treated for patellar tendonitis after an ACL reconstruction but there is no presented or published information about the specifics of his treatment. In Kobe's case, he may have been treated for knee arthritis but despite BLOODCURE contacting its many sources in the USA and Europe, no one has come forward with specific information about his treatment. What did he have done and why did he travel to Germany to get it done? Plenty of physicians within the USA and specifically California have experience with PRP. So, did he get some form of PRP that is not available in the USA?
Answers to these questions will help us all better understand the value of PRP for iconic professional athletes and for sports medicine in general. Importantly, we also need to learn what type of PRP (many exist) they received. Here is a video of a PRP Classification System.
If anyone has information about these cases, please post a comment below.
