Adult flat foot, also known as adult acquired flatfoot deformity (AAFD), or progressive collapsing foot deformity (PCFD), is a condition where the arch of the foot collapses, leading to the entire sole coming into contact with the ground. This condition often develops over time and can cause significant pain and difficulty with walking or standing for long periods.
The most common cause of adult flat foot is posterior tibial tendon dysfunction (PTTD). This tendon supports the arch of the foot, and when it becomes inflamed or torn, the arch may gradually collapse. Other causes include arthritis, injury, obesity, diabetes, or previous foot trauma.
Symptoms of adult flat foot include pain along the inner side of the foot and ankle, swelling, difficulty walking, and a noticeable flattening of the arch. In more advanced cases, the foot may turn outward, and pain may spread to the outer ankle and lower leg. Left untreated, the condition can lead to permanent deformity and joint damage.
Diagnosis typically involves a physical examination and imaging tests such as X-rays or MRI to assess the structure of the foot and the condition of the posterior tibial tendon.
Treatment depends on the severity of the condition. Early stages may be managed with non-surgical methods, including rest, orthotic devices, physical therapy, and anti-inflammatory medications. Supportive footwear and braces can help relieve symptoms and prevent further progression. In more severe or unresponsive cases, surgery may be required to repair the tendon, realign the bones, or fuse joints.
Adult flat foot is a progressive condition that benefits from early intervention. If you experience persistent foot pain or notice changes in your foot’s shape or function, it’s important to seek evaluation by a medical professional, such as an orthopaedic surgeon specialising if foot and ankle conditions. Prompt treatment can help maintain mobility and reduce the risk of complications.
