Adult-acquired flatfoot deformity (AAFD) is a painful, progressive condition that occurs when the soft tissues of the foot are overstretched and torn, causing the arch of the foot to collapse.
The posterior tibial tendon attaches to the bones on the inside of the foot, maintains the foot’s arch and provides the strength needed for feet to effectively push-off while walking. When this tendon loses its function, the bones will spread out of their aligned position and the foot will become “flat”—causing individuals to develop adult-acquired flatfoot deformity.
Without an AAFD repair, the condition may progress until the affected foot becomes entirely rigid and quite painful.
Common risk factors associated with adult-acquired flatfoot deformity include:
Common symptoms of adult-acquired flatfoot deformity include:
Diagnosis for adult-acquired flatfoot deformity is accomplished through a combination of physical evaluations and imaging tools, such as X-rays and MRIs.
If caught early, adult-acquired flatfoot can be effectively managed through non-surgical treatments, such as bracing, custom-molded orthotics or cast immobilization.When conservative care fails, our physicians will select a surgical treatment that will restore mobility, reduce pain and stop the progression of this serious foot condition. A surgical treatment will be selected that best suits your needs. Procedure options include tendon transfer, tendon debridement and joint fusion. Our foot and ankle surgeons may also perform an osteotomy, which involves surgically cutting and reshaping a bone to realign the foot.
