Surgical Procedure – Achilles Rupture Tendon Surgery
Surgery should be considered to relieve an Achilles Rupture Tendon Surgery only if the pain does not improve after 6 months of nonsurgical treatment. The specific type of surgery depends on the location of the tendinitis and the amount of damage to the tendon.
Gastrocnemius recession. This is a surgical lengthening of the calf (gastrocnemius) muscles. Because tight calf muscles place increased stress on the Achilles tendon, this procedure is useful for patients who still have difficulty flexing their feet, despite consistent stretching.
In gastrocnemius recession, one of the two muscles that make up the calf is lengthened to increase the motion of the ankle. The procedure can be performed with a traditional, open incision or with a smaller incision and an endoscope—an instrument that contains a small camera.
Complication rates for gastrocnemius recession are low, but can include nerve damage.
Gastrocnemius recession can be performed with or without débridement, which is removal of damaged tissue.
Débridement and repair (tendon has less than 50% damage). The goal of this operation is to remove the damaged part of the Achilles tendon. Once the unhealthy portion of the tendon has been removed, the remaining tendon is repaired with sutures, or stitches to complete the repair.
In insertional tendinitis, the bone spur is also removed. Repair of the tendon in these instances may require the use of metal or plastic anchors to help hold the Achilles tendon to the heel bone, where it attaches.
After débridement and repair, most patients are allowed to walk in a removable boot or cast within 2 weeks, although this period depends upon the amount of damage to the tendon.
Débridement with tendon transfer (tendon has greater than 50% damage). In cases where more than 50% of the Achilles tendon is not healthy and requires removal, the remaining portion of the tendon is not strong enough to function alone. To prevent the remaining tendon from rupturing with activity, an Achilles tendon transfer is performed. The tendon that helps the big toe point down is moved to the heel bone to add strength to the damaged tendon. Although this sounds severe, the big toe will still be able to move, and most patients will not notice a change in the way they walk or run.
Depending on the extent of damage to the tendon, some patients may not be able to return to competitive sports or running.
Most patients have good results from surgery. The main factor in surgical recovery is the amount of damage to the tendon. The greater the amount of tendon involved, the longer the recovery period, and the less likely a patient will be able to return to sports activity.
Physical therapy is an important part of recovery. Many patients require 12 months of rehabilitation before they are pain-free.
Complications. Moderate to severe pain after surgery is noted in 20% to 30% of patients and is the most common complication. In addition, a wound infection can occur and the infection is very difficult to treat in this location.
