If you have a ruptured Achilles tendon, instead of having surgery you may use a cast, splint, brace, walking boot, or other device that will keep your lower leg from moving (immobilization). When immobilized over a period of months, the Achilles tendon can slowly reattach and heal.

Considerations

Immobilization is a wise treatment choice for some people, but not for others. When deciding on treatment for an Achilles tendon rupture, consider your level of activity, your need for leg strength at home or at work, and your age and medical condition.

Consider the following when deciding whether surgery or immobilization is best for you:

• There are no surgical risks associated with immobilization.
• After immobilization, an Achilles tendon is more likely to rupture again than it would be after surgical treatment. However, if you are not physically active in sports, at home, or at work, then your risk of rerupturing the tendon is minimal, and immobilization may be sufficient treatment for your needs.
• After immobilization, your leg is more likely to be weaker than after surgery.
• The recovery period after immobilization is longer (as long as 6 months) than after surgery.

Immobilization is usually followed by a rehabilitation program, which may include stretching, exercising, and physical therapy.
