In a book the review of results of interdisciplinary researches of processes of relaxation of tensions and regeneration of cartilaginous fabric is first given under the action of laser radiation, that resulted in creation of fundamentally new medical technologies and equipment for treatment of the deformed and damaged cartilages by the non-destructive laser affecting structure and field of mechanical tensions in biological fabrics. Book intended to the wide circle of different specialists : to the scientists - physicists, chemists, biologists, - engaging in the fundamental processes of the laser affecting biological systems and elaborative new methods in biology and medicine| to the doctors - otolaryngologists, plastic surgeons, cosmetologists, orthopaedists, спинальным surgeons, - using or designing to apply new littleinvasion technologies for treatment of cartilages| to the engineers working in area of laser medical technique and technology.
