What causes an Achilles tendon rupture?

Sudden movement that puts stress on the Achilles tendon can lead to a rupture. Typically, people tear the Achilles tendon while playing sports. The biggest culprits are sports with sudden stops, starts and pivots — such as soccer, football, basketball, tennis or squash. Achilles tendon tears aren’t always a sports injury. You can tear your Achilles tendon by tripping, missing a step when going downstairs or accidentally stepping into a hole and twisting your ankle. Some medications — including certain antibiotics and steroid injections in the area — can weaken the Achilles tendon. This can put you at a higher risk for a tear.
