[Evaluation of physical disability after knee injuries].

Medical expert opinions about knee injuries are often complicated by lesions of some parts of joint-structures. The assessment of disablement has always to consider, the dimension (objective signs) and the case history. Wellknown anatomic variations are to note. In cases with measurable consequences of accident must be proved adequate traumas because of elasticity, tensile and breaking strength of the structures of the knee-joint. A scale for rating of bodily disability after severe knee-joint injuries is proposed from 5-10% to 30-35%.
