Achilles Tendon Ruptures: Causes, Symptoms, and Treatment

The Achilles tendon—the strong band of tissue that connects your calf muscles to your heel bone—is the largest tendon in the body. It helps you walk, run, jump, and push off with your foot. But when this tendon tears, even partially, it can cause sudden pain and significantly limit mobility. An Achilles tendon rupture is a serious injury, but with prompt treatment, most people recover well.

Causes of an Achilles Tendon Rupture

A rupture often happens during activities that place sudden stress on the tendon. Common causes include:

Sports injuries – Jumps, or sudden acceleration in sports like basketball, soccer, or tennis.

Sudden increase in activity – Going from a sedentary lifestyle to intense exercise without proper conditioning.

Falls or missteps – Landing awkwardly on the foot or stepping into a hole.

Tendon degeneration – Age, overuse, or chronic tendinitis can weaken the tendon, making it more prone to tearing.

Men over 30 are at slightly higher risk, especially those who participate in recreational sports. Weekend warriors!

Symptoms of a Rupture

An Achilles tendon rupture usually causes noticeable and sudden symptoms, such as:

A “pop” or snapping sound at the back of the ankle

Sharp, severe pain in the calf or heel area

Swelling and stiffness near the heel

Difficulty walking or standing on tiptoe

Feeling like the back of the leg was “kicked” or struck by a ball.

Treatment Options

Treatment depends on the severity of the rupture, your activity level, and overall health. Options include:

Nonsurgical treatment – In some cases, immobilizing the foot and ankle in a cast, boot, or brace can allow the tendon to heal. Physical therapy is usually recommended afterward to restore strength and flexibility.

Surgical repair – Many patients, especially those who are active, may benefit from surgery to stitch the torn tendon back together. Surgical treatment often lowers the risk of re-rupture and can help restore full function.

Rehabilitation – Whether surgery is performed or not, rehab is crucial. Gradual stretching, strengthening, and activity progression help ensure the tendon heals properly.

When to See a Specialist

If you hear a popping sound in your ankle, suddenly can’t push off with your foot, or experience severe heel pain, it’s important to seek medical care immediately. Early diagnosis and treatment greatly improve the chances of a successful recovery.

Bottom line: An Achilles tendon rupture is a painful injury that can stop you in your tracks. But with timely orthopedic care and proper rehabilitation, most patients regain their strength and mobility—and get back to doing the activities they enjoy.
