Final answer:
Prosthetics are devices engineered to replace lost limbs or body parts. They are mainly designed by bioengineers to help amputees lead more active lives, with advancements in joint replacements for hips, knees, and other body parts.
Step-by-step explanation:
Devices which replace lost limbs or other body parts are called prosthetics. Prosthetics are engineered by bioengineers, combining knowledge in physics, chemistry, biology, and medicine to address and solve medical and health-related problems.
Significant advancements have been made in the field of prosthesis design, particularly with the development of artificial joints. Joint replacement surgeries, especially for hips and knees, have become quite common, and prosthetics for shoulders, elbows, and fingers are also available. Technological progress continues as researchers aim to create more durable prosthetic solutions using materials like carbon fiber for active individuals.
