Development on rehabilitation instrument of genu varum and genu valgum based on biomechanics

Aiming at flaws of patient´s pain and high expense caused by surgical treatment of genu varum and genu valgum, this paper puts forward a new method based on biomechamics and cartilage-derived growth theory to cure genu varum and genu valgum, in which different kinds of the external force are imposed on knee to stimulate the histiocytic growth of different parts of patient´s knee, and develops a prototype and does experiments. The results show that patients have little anguish, low expense, without operation and make obvious effect after they has been cured from three to six months.
