The Flex-Foot Cheetah is a prosthetic human foot replacement developed by biomedical engineer Van Phillips, who had lost a leg below the knee at age 21; the deficiencies of existing prostheses led him to invent this new prosthesis. The Flex-Foot Cheetah and similar models are worn by Oscar Pistorius and other amputee athletes in the Paralympics ...
The mechanics of the running blades used by South African former Paralympic runner Oscar Pistorius depend on special carbon-fiber-reinforced polymer prosthetics. Pistorius has double below-the-knee amputations and competed in both non-disabled and T44 amputee athletics events. Pistorius's eligibility to run in international non-disabled events ...

Hugh Herr (born October 25, 1964) is an American rock climber, engineer, and biophysicist. When he was young, both of his legs were amputated below the knee during a blizzard in a rock climbing trip. [1] After months of surgeries and rehabilitation, Herr began climbing again, using specialized prostheses he designed for himself, becoming the ...
From left to right, the athletes are Oscar Pistorius, Jerome Singleton and Arnu Fourie. T44 is a disability sport classification for disability athletics, applying to "Single below knee amputation or an athlete who can walk with moderately reduced function in one or both legs." It includes ISOD A4 and A9 classes.
Rotationplasty allows the use of the knee joint, whereas amputation would result in loss of that joint. Therefore, it provides a better attachment point and range of motion for a prosthetic limb. As a result, children who have had rotationplasty can play sports, run, climb, and do more than would be possible with a jointless prosthetic.
The transition from an orthosis to a prosthesis can be fluid. An example is compensating for a leg length discrepancy, equivalent to replacing a missing part of a limb. Another example is the replacement of the forefoot after a forefoot amputation. This treatment is often made from a combination of a prosthesis to replace the forefoot and an ...
After a Paralympic marathoner was disqualified and lost out on a bronze medal because her guide, Mia Carol, suffered a cramp at the finish line, Carol is speaking out against the "injustice" of ...
