Achilles injury refers to damage or trauma to the Achilles tendon, a strong fibrous cord that connects the muscles in the back of the calf to the heel bone. There are two common types of Achilles tendon injuries:
-
Acute rupture: This occurs when the tendon is stretched beyond its capacity, resulting in a complete or partial tear. It mainly affects people playing recreational sports, but it can happen to anyone. Symptoms of an acute rupture may include a popping sound, immediate sharp pain in the back of the ankle and lower leg, and difficulty walking properly.
-
Achilles tendinopathy: This is a chronic (long-term) condition that causes weakness and degeneration of the Achilles tendon due to a series of very small tears (tendinosis). Symptoms of Achilles tendinopathy may include weakness or stiffness at the back of the heel, swelling, and decreased strength and movement.
