There are many misconceptions around the use of stem cells. One of them is that embryos and foetuses are destroyed in order to provide stem cell treatments. This clearly is not the case. The use of embryonic stem cells is illegal both in the United Kingdom and in Europe.
The stem cells that are used for treatments are adult stem cells which are harvested from the same individual that is being treated.
There is also a misconception that stem cells can cure absolutely everything. This is certainly not the case as with any treatment modality there are failures. In most orthopaedic treatments anywhere between 5% to 30% of individuals having a surgical procedure end up not having the full benefits that the surgical procedure intends. It is the same with a variety of non-surgical treatments including physiotherapy, manual therapy, injections of various compounds including steroids and of course, stem cell treatments.
