What Kind of Surgery Is Available for Flat Feet?

The American Orthopaedic Foot and Ankle Society says surgical intervention for flat feet involves a combination of procedures performed on the bone to restore the arch of the foot and on the ligaments and tendons to repair the arch's support. This surgical correction improves the alignment of the foot.

Patients are candidates for surgical reconstruction of the flat foot when their arch collapse is still flexible, not stiff, says the American Orthopaedic Foot and Ankle Society. They list specific corrective surgeries, including medializing calcaneal osteotomy, used when the heel bone has shifted out from underneath the leg; dorsal opening wedge osteotomy of the medial cuneiform bone to treat the big toe side of the foot being raised above the ground; and numerous tendon and ligament procedures to remove the posterior tibial tendon if it has stiffened, and reroute the tendon that moves the pinkie toe to help support the arch.
