Aim of paper: The aim of this paper is, with the right choice of medical literature, to describe a case of an Achilles tendon shortening in childhood, which causes the patients to walk on their toes. Furthermore, to emphasize the seriousness of the situation and to show the physiotherapeutic evaluation and implementation of habilitation treatment and physical therapy for this anomaly. And at last, to point out the omissions of the parents and the patient. Case report: Patient N.N., due to walking on his toes, comes for an examination by a specialist in physical medicine and rehabilitation, where all neurological diseases are ruled out and he points to a congenital anomaly. At the second examinaton, the patient N.N. was more accurately diagnosed, with various tests revealing a weaker form of shortening of the Achilles tendon and the inability to perform dorsiflexion in the ankle. Patient N.N. is referred for habilitation with physical therapy for a period of two months, twice a week. Conclusion: Congenital shortening of the Achilles tendon is an increasingly common phenomenon in children. Toe walking, which is characteristic in children with a shortened Achilles tendon, causes significant concern for parents. In this case, the patient N.N. completed the prescribed therapy, but the doctor’s examination was not repeated, so we do not know the precise results of the therapy. Along with the prescribed therapy, the child is, to this day, an avid soccer player. This can be concluded to produce results contrary to the therapy. In this paper we can see the results of repeated physiotherapeutic evaluation and the overall condition of the patient.
