The recovery time for Achilles tendon surgery is six months, according to WebMD. Expect to wear a cast for the first six to 12 weeks of recovering from surgery. Most surgeries do not take place until the swelling comes down after the rupture. This can take up to a week.
The position of the cast is altered during recovery time, states WebMD. First it's pointed downward, then moved to a neutral position as strength returns. More than 80% of people who have Achilles tendon surgery enjoy a full recovery. An important factor in recovery is having a good rehabilitation program and following it.
