An artificial leg, also known as a prosthetic limb, is a device designed to replace a missing or non-functional leg. Some synonyms for artificial leg include prosthetic leg, mechanical leg, bionic leg, and prosthetic limb. The use of synonyms may vary depending on the medical context and level of technological advancement of the prosthetic. Advances in prosthetic technology have led to the development of more advanced prosthetic legs with features that mimic natural movements, such as computer-controlled microprocessors and motorized joints. Regardless of the term used, the goal of artificial legs is to provide mobility and improve the quality of life for individuals who have lost a limb.
