Other Important Information[edit | edit source]

Is it a real muscle or a gost?[edit | edit source]

For physiotherapist vastus medialis oblique (VMO) is a well known muscle. But some anatomist do not accept VMO as real muscle. The first paper I have seen was a letter to editor [ref needed]. In this letter it is clearly stated that VMO is not an independent muscle. It is a part of vastus medilis. 

Recent years the topic is still unclear.  You can find a list of articles below;
