The paper discusses a biomechanical model reflecting deformation and tear of a tendon part, namely, ellipric in cross-section strand formed by stochastically located collagen fibers whose strain to stress relation obeys the exponential law. Recovery of the tendon by a plastic reinforcement is shown to result in elevated rigidity and shorter limiting elongation of the strand proportionally to the reinforced portion length, the strength of the restored strand being preserved almost fully. The limiting deformation of the recovered strand made with incisions for adaptation of the ends increases the more the deeper are the incisions, their number and the total length of the areas being adapted. This, nevertheless, decreases essentially the breaking load during further loading.
