The Achilles tendon is the largest and strongest tendon in the human body, and is named after the Greek hero Achilles. It is susceptible to injuries such as ruptures and overstrain, which are common in professional and recreational athletes. When the Achilles tendon ruptures, there is pain, swelling, and loss of function. Tendon injuries are most common in middle-aged men and occur in various sports such as football, tennis, handball and basketball. There are two theories about the origin of the injury: the degenerative theory and the mechanical theory. Education is important for patients with Achilles tendon injuries. The patient should be educated on how to walk with crutches and how to place the orthosis. The patient should also be educated about the diseases he suffers from and shown exercises that he can do independently. Physiotherapy procedures are aimed at reducing atrophy, reducing the rate of rupture and increasing the range of motion. The aim of physiotherapy procedures is to allow the tendon to heal normally, to return to normal range of motion, strength and endurance, and to achieve the level of activity the patient was at before the injury. Physiotherapist role is primarily to be an educator, motivator and to make a maximum contribution in therapy process. Prevention and effective treatment of Achilles tendon injuries are key to returning patients to their previous level of activity. Education, rehabilitation protocols and a holistic approach are necessary for successful recovery.
