Introduction: Sprains are one of the most common injuries in sports. They are a result of excessive movement in the joint, which exceeds the physiological limit. Signs that a sprain occurred are swelling in the joint area, pain upon pressure and painful movement in the joint. Purpose: The purpose of the diploma work is to present the late postoperative physiotherapeutic treatment of an athlete with a lateral ankle sprain and an injury of the front ligament in the foot and to describe the applied physiotherapeutic procedures on the basis of scientific literature. Work method: The diploma work is a case report. The physiotherapeutic assessment of the patient started with the medical history and continued with a physical examination. They were followed by linear measurements of mobility ranges, manual muscle testing, measurement of lower limbs girth, pain measurement using the VAL-PI scales, assessment of superficial sensory according to appropriate dermatomes, four square step test, 10-meter walking test and the standing on one foot test as a modified clinical test of sensory interaction. According to the assessment of the patient's condition, we highlighted the problems, short-term and long-term goals and selected appropriate physiotherapeutic procedures. Results: At the end of the physiotherapeutic treatment, the swelling of the right foot over the heel bone subsided by 1 and under the heel and under the ankle by 0.5 cm, the flexibility of the right upper and lower talocrural joints improved, the pain in the scar area on the right foot decreased by 2.8 mm according to the VAL-PI scale, the strength of the ankle muscles improved. Similarly, the results of the 10-meter walking test, the four square step test and the standing on one foot fest as a modified clinical test of sensory interaction test also improved. Discussion and conclusion: The goals we set at the beginning of the physiotherapeutic treatment were achieved through appropriate physiotherapeutic procedures during the therapy. The patient was treated individually during rehabilitation, which contributed to a greater final success. In addition, he showed great motivation and concentration during the therapy.
