The new substance will restore even severely damaged the cartilage and meniscus

Our body is pretty good recovery after different types of injuries. However, some tissues, such as cartilage, owing to its anatomical structures have a poor blood supply. This is due to a number of reasons, but there is a problem: when damage occurs to the cartilage and chondroid structures they regenerate very poorly. However, the new invention of scientists from Switzerland will help to solve this problem.

According to the editorial office Phys.org the new development is a special kind of hydrogel, mixed with medicinal substances and structures for the regeneration of cartilage. The main advantage of the new hydrogel is that it does 90% better than all existing analogues, while stimulating the regeneration of tissues. In addition, existing medical hydrogels are very poorly held in place and therefore, physicians are forced to use a special locking system, which often can injure the surrounding tissue. And in some cases damaged cartilage pulling mechanically.

The Research team, led by Dominic Paoletti and Pierre Etienne burbano created a biocompatible hydrogel, which is almost 90% water, withstands mechanical stress and severe deformation, and therefore eliminates the need for additional "bindings"

"Our hydrogel is ten times more sticky than currently available on the market bioadhesive substances, such as fibrin. And due to the high content of water, our hydrogel is very similar in nature to the natural tissue."

The New hydrogel is actually a composite material consisting of dvuhkletevoj of the matrix or fibrous network. This structure allows to save the shape to be quite "sticky" and resist mechanical impact.

"Double network structure distributes the incoming mechanical energy throughout the hydrogel, so that the material shows the improvement of adhesion in compression or tension», — said Mr. Paoletti. "In hydrogels that do not have these mechanisms, mechanical tension at the interface of the hydrogel and the tissue, so the hydrogel comes off easily enough."

Moreover, the new hydrogel could find applications not only in splicing chondroid structures, but in the future may even replace the metal plates, which are now often used for the treatment of fractures. For this purpose, according to the researchers, it is necessary only "to adapt to work with a specific type of tissue" than scientists are doing at the moment.
