Why do feet swell one year after bilateral knee replacement?

Feet may swell one year after bilateral knee replacement due to several factors, including fluid retention, changes in mobility, or residual inflammation from the surgery. Additionally, altered gait mechanics and increased pressure on the feet can contribute to swelling. In some cases, underlying conditions such as venous insufficiency or lymphedema may also exacerbate the issue. It's important to consult a healthcare professional for personalized evaluation and management.
