This study presents results of ultrasonographic examination of 14 children (21 feet) with congenital clubfoot of the 3d-4th degrees, treated by the Ponseti method, in whom no convincing single-step Achilles tendon transection was achieved in transverse tenotomy. Experimental part of the study was performed on 25 growing Chinchilla rabbits, in which fascias and mesenteric vessels of the Achilles tendon were transected during subcutaneous tenotomy. Ultrasonographic examination performed in children showed that main conditions necessary for maturation and remodeling of the regenerated Achilles tendon and increase of its strength are compliance with adequate motion regimen and its timely expansion with kinesitherapy. Histologic examination of the regenerated zone of the heel tendon in animals with a low functional load on lower limbs showed that regenerate formation was incomplete as compared with patients for which rehabilitation activities had been performed. When performing rehabilitation measures for children with congenital clubfoot treated by the Ponseti method, it is necessary to consider the character of Achilles tendon transection, time after the surgery and particulars of reparative regeneration in the Achilles tendon transection zone, defined by ultrasonographic examination data
