Suprunov showed the problem of children's treatment who have the posttraumatic deformations of knee-joint in combination with shortening of limbs.With the help of experiemental machine ''Zwick-1464'' and the use of anatomic preparations of children's bones:thigh-bone and shin-bone we studied a distribution of contact pressure on articular surface depending on type,degree of deformations and age's index.We took the sizes of contact's places of articulate surfaces.We calculated the indexes of specific pressure in the area of condules of the thigh-bones and shin-bones by the axle load from 330 to 500 H.We noted the zones of elastic and plastic deformations.For elastic deformations we used the term ''safe'', for plastic deformations - ''injuring''.Under observations there were 13 patients,who had 16 operations.Operative treatment on the basis of biomechanical aspects can exclude or decrease the risk of deforming arthrosis' development and can improve cosmetic and functional result of treatment.
