Surgery to repair a torn (ruptured) Achilles tendon involves making an incision or cut in the back of the leg above the heel to access the torn tendon. The tendon is then sewn back together. Surgery may be delayed for about one week after the rupture to let the swelling go down.
After surgery, a cast or walking boot is usually worn for six to 12 weeks. At first, the cast or boot is positioned to keep the foot pointed downward as the tendon heals. The cast or boot is then adjusted gradually to put 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.
