Study of the influence of autothrombocytic growth factors upon the injured tendinous tissue was performed. Experimental results (60 Chinchilla rabbits, 3—5 kg) showed that administration of autologous platelet-rich plasma (PRP) into Achilles tendon (AT) injury zone promoted activiza- tion of reparative processes with diminution of inflammatory manifestations; increase in angio- genesis, proliferative and synthetic fibroblasts activity, fibrillogenesis processes; earlier tendon healing. Clinical study included 57 patients (33—68years) with acute (8—48 hours) and old (1—12 months) AT ruptures. After AT surgical reconstruction(Cuneo tendon sutures in acute AC ruptures and Chernavsiautoplasty in the old ones) PRP was additionally administrated to 30 patients from the main group. Treatment results were evaluated by J. Leppilahti and AOFAS scales in 4 months after surgical intervention. In no one patient from the main group AT reruptures were recorded while in control groupreruptures were recorded in 26% of patients.
