Plantar fascia release surgery involves cutting part of the plantar fascia ligament to release tension and relieve inflammation of the ligament. Your doctor can use medication that numbs the area (local anesthetic) for the procedure. Plantar fascia release can be done by cutting the area (open surgery) or by inserting instruments through small incisions (endoscopic surgery). The surgeon will make an incision on the foot above the heel pad, where the thicker skin of the sole meets the thinner skin of the back of the heel, or he or she may make an incision on the bottom of the foot. If the surgery is done endoscopically, the surgeon will make a small incision on either side of the heel below the ankle bone.
