This procedure lengthens a tight Achilles tendon, which can prevent the foot from bending upward at the ankle, allowing increased motion at the ankle joint. It may be used in combination with another procedure (for example, to apply internal or external fixation) to correct lower limb deformity.
There are three methods in general use; all require some form of surgery under anesthetic. Each technique has benefits depending on the circumstances and the severity of the condition. These options should be discussed with a surgeon.
Recovery time is about six to eight weeks. A very tight Achilles tendon may require more-complex lengthening surgery, which is more invasive and takes longer to heal. After surgery, patients may be placed into a protective cast, splint or walking boot, followed by physical therapy.
