Fabella is a tiny bone in the knee that a century ago it was considered endangered during evolution rudimentary body. However, lately she has become meet more and more among the inhabitants of our planet.
If in 1918 only 11% of earthlings had fabella in at least one leg, today it is present in 39% of people. This sesame-shaped the bone grows in the thickness of the tendons behind the knee and anatomically resembles a microscopic patella.
Doctors still cannot determine why this rudiment returns to the human body and why it is needed. First physicians thought Fabella was just a harmless, unnecessary organ, however, experts have now concluded that her presence in the knee may cause osteoarthritis. There were even doctors who recommended to everyone who has fabella to remove it surgically so as not to suffer in old age from deforming osteoarthritis.
It is hypothesized that the fabella went to the person from monkeys in which she increased mechanical efficiency knee joints. Man, they say, evolved and began to lose given bone. Despite this, in recent decades, more people began to suffer from overweight due to a fatty diet and wrong lifestyle. Pressure on our knee joints increased, and it’s precisely it that allegedly leads to the formation of “lost” sesamoid bone.

Today, every biology textbook indicates that the human skeleton consists of 206 bones. However, in the future, perhaps, such data recognized as obsolete, and there they will talk about 206-208 bones, since many people already have one or both fables. This a bone, many doctors consider, can be called an appendix skeleton, “because it is not only useless, but can also serve cause health troubles. In contact with the knee cartilage, it leads to severe osteoarthritis.
However, today scientists are increasingly coming to the conclusion that in the human body is nothing superfluous, and the same appendix or In no case should tonsils be removed unless absolutely necessary. It is possible that some time and true purpose will pass fabella, like appendix, will be understood, as well as the reasons why this “extra bone” in the knee returns to the person during its further evolution …
