It seems to me that knees are a hot topic of discussion on this forum, so readers may be interested in this article: I find it fascinating that we can send people into space but still don't have a complete understanding of human anatomy! The important thing is that this new knowledge may improve knee surgery and help more patients to gain a full recovery. If this ligament turns out to be a hidden factor in chronic knee complaints, it maybe a good candidate for PRP. Anything that can help to keep knees in tip-top condition for longer has got to be a good thing for all, but especially sports fans. Too many players have had to retire early due to knee conditions. Hopefully this will soon be a thing of the past.
