Can an Achilles tendon repair itself?

A partial tear of the Achilles tendon may sometimes heal without surgery if the torn ends remain closely aligned and the ankle is immobilised in a boot or cast. In these cases, your consultant may recommend a non-surgical rehabilitation programme involving rest, controlled movement, and physiotherapy to allow the tendon to heal naturally.

However, a complete rupture of the Achilles tendon cannot reliably repair itself. Without surgical repair, the torn ends usually separate, leading to weakness, loss of power when pushing off the foot, and difficulty walking or returning to sport. For these injuries, surgical repair offers the best chance of regaining full strength and function. Your consultant will assess your injury with ultrasound or MRI imaging and recommend the most appropriate treatment based on the severity of the tear, your age, activity level, and goals.
