The Achilles tendon is a strong fibrous cord that connects the muscles in the back of your calf to your heel bone. If you overstretch your Achilles tendon, it can tear (rupture) completely or just partially.In cases when Achilles tendon ruptures, you might feel a pop or snap, followed by an immediate sharp pain in the back of your ankle and lower leg along with foot pain that is likely to affect your ability to walk properly. Some individuals may have had previous complains of calf or Achilles heel pain, suggesting prior tendon inflammation or irritation.Surgery is often the best option to repair an Achilles tendon rupture.Patients are typically seen in the office two weeks after surgery. The splint or cast is removed and the surgical incision done by an orthopedic is evaluated. Stitches are usually removed at this time if they need to be removed at all. From two weeks to six weeks, the postoperative protocol varies based on surgeon preference. Patients may be allowed to begin weightbearing in a walking boot. Ankle motion is often allowed and encouraged. A cast is sometimes used instead of a boot. At six weeks patients are usually allowed full weightbearing out of the cast or boot. Physical therapy is started and is aimed at restoring ankle range of motion. Strengthening of the calf muscles and Achilles is gradually allowed as the tendon heals. Patients are usually able to return to full activity by six months. It may be over a year before a patient achieves full recovery.
