When Achilles Injuries Require Surgery
Surgery to repair a torn or ruptured Achilles tendon is conducted on an outpatient basis. A local anesthetic is used and an incision or cut is made in the back of the leg above the heel. This allows access to the torn tendon. The surgeon then sews the tendon back together.
If there is a lot of swelling, surgery on the tendon may be delayed for about one week after the rupture. That will allow time for the swelling to go down.
Post-surgery, the patient typically wears a walking boot for six to twelve weeks. At first, the cast or boot is positioned to keep the foot pointed downward while the tendon heals. Then the cast or boot is adjusted gradually to position the foot in a neutral position (not pointing up or down).
Specific gentle exercises (restricted motion) after surgery can shorten the time needed in rehabilitation.
