A prosthetic device, such as an artificial foot or leg, may provide many benefits for a patient after the amputation of a limb. One of the greatest benefits is mobility. Though patients may not regain their full abilities from before the surgery, many are able to live largely independent lives. Technological advances in prosthetics now allow patients to perform many recreational activities, including swimming, hiking and skiing.

There are also other benefits of a prosthetic, including:

• Reduction of “phantom” pain from the amputated limb
  
  
• Aesthetics, which helps boost the confidence of some patients after an amputation

Though prosthetics provide several benefits, they also pose some risks. Using a prosthetic leg requires more energy than a natural limb and can cause fatigue. Patients will need more strength to perform the same tasks they did before the amputation. This may lead to frustration and depression. Another risk is that of a second amputation. In some cases, especially in patients with diabetes, an injury to the remaining limb may become infected and require another amputation.

Skin problems may also occur, such as rash or irritation due to materials the residual limb is in contact with (e.g., sock or gel liner, suspension mechanism). A poorly fitting prosthesis can also cause friction, which may also cause skin problems.
