Achilles tendon rupture is a tear or complete separation of the Achilles tendon, which connects the calf muscles to the heel bone. It often occurs during activities involving sudden stops or changes in direction and is more common in middle-aged individuals who participate in sports. Symptoms include a sudden onset of pain, swelling, difficulty walking, or pointing the toes. Treatment options include non-surgical approaches such as immobilization with a cast or walking boot, or surgical repair for severe cases. Physical therapy is typically recommended to regain strength and flexibility in the Achilles tendon.
