Unfortunately, if you look at the practice of medicine today and especially at the field of so-called regenerative medicine, this is how it's called today, you will see that it's totally distorted by the idea of replacing this natural process with poor artificial limitations. So take, for example, osteoarthritis of the knee. So the condition generally age and is related to the loss of the cartilage that protects the contact surfaces of the bone. And for decades, it was assumed that the knee, the osteoarthritis is quite simply a result of this unavoidable wear and tear of the joint of the knee joint. And according to this logic, you can't do anything about it. It's just a mechanical part. So for a can take anti-inflammatory drugs to slow down this deterioration. But then eventually, the only choice is to have a knee replacement, hip replacement and so on. So such approach is not surprising, what is seen as a very complicated mechanism. So on one hand, no one questions the ability of the skin and finger to regenerate, but when it comes to the knee, you say, well, we can't do much about it. But what if the body still possesses the know-how, how to regenerate the damaged tissue? So now the question is, can it be done with technology, but not in a invasive way, but rather in a life-supportive way?
