Lower Leg

Plantaris Tear

A plantaris tear or rupture is commonly called “tennis leg.” It is a result of an eccentric load placed on the ankle while the knee is extended. It occurs during running, cutting, or jumping activities. It may be caused by direct trauma to the calf area. Pain and swelling are common in the injury.

Diagnosis

Your doctor can diagnose a plantaris tear by taking a medical history and performing a physical examination. An MRI and ultrasound imaging may also be used to confirm the injury.

Treatment

Once diagnosis is confirmed, rest followed by rehabilitation can reduce pain and encourage healing.
