Adult acquired flatfoot deformity (AAFD) is a condition where the arch of the foot collapses over time, causing the foot to become flatter and wider. This can result in pain, instability, and difficulty walking or standing for long periods of time.
The most common cause of AAFD is damage to the posterior tibial tendon, which is responsible for supporting the arch of the foot. Risk factors for AAFD include age, obesity, diabetes, and prior foot or ankle injuries.
Symptoms of AAFD may include pain and swelling along the inside of the ankle, a noticeable flattening of the arch, and difficulty standing or walking on the affected foot. Some people may also experience weakness or numbness in the foot or ankle.
Treatment for AAFD may depend on the severity of the condition and the patient’s overall health. Non-surgical treatment options may include rest, ice, physical therapy, and the use of orthotic devices or supportive shoes to help alleviate pain and improve stability. In some cases, the use of braces or immobilisation devices may be necessary to reduce stress on the affected foot.
Surgical treatment for AAFD may be necessary in more severe cases, particularly if non-surgical treatments have not been successful. Surgery may involve repairing or reconstructing the damaged posterior tibial tendon, or fusing the affected joints in the foot to provide greater stability and support. Recovery from surgery may require a period of immobilisation and rehabilitation to restore strength and function to the affected foot.
