Adult Acquired Flat Feet
Adult acquired flat foot is most commonly characterised by pain and swelling around the inside of the ankle, due to soft tissue changes.
It is most commonly seen in women over 40, but can present in either sex at any age. Usually it occurs in only one foot along with ankle pain and difficulty walking. It shouldn’t be confused with inherited flat feet, which occurs in both feet from a very young age and is normal.Â
Because of its progressive nature it is best dealt with as early as possible, where conservative measures are best placed.Â
Flat feet can be caused by:
- Trauma
- High BMI and sedentary lifestyle
- Diabetes, high blood pressure and inflammatory disorders
- Steroids – orally and locally (injection) administered
- Reduced hip and ankle strength or flexibility
- Occasionally following knee surgery.
This can be as simple as removing some of the causes such as changing ill-fitting, worn-out footwear, losing weight or modifying activities to non-weight-bearing exercise such as swimming or cycling.
The most common pain relief solutions are:
- Modification to lifestyle (including work environment).
- Rest, avoid prolonged activity such as standing, walking and sports.
- Strapping and taping.
- Weight lossÂ
- Use of supportive footwear
- Orthotic insoles.
- Ice massage
- Stretching and strengthening exercises
