About K12 Prosthetics

Formerly SymBiotechs USA, K12 PROSTHETICS is a prosthetic components company focused on empowering active amputees with the devices they need to accomplish the impossible! Founded by Jarem Frye, (the world’s first AK amputee telemark skier, competitive AK Wakeboarder, pro rock climber and winner of the first ever eXtremity Games rock climbing championship) K12 PROSTHETICS follows Jarem’s vision of ability rather than the standard idea of disability which Jarem was presented with at his amputation.


As a company K12 PROSTHETICS believes in breaking barriers, setting records and inspiring others to break those records! We believe in every amputees ability to do great and impossible things! The XT9 Energy Storing Prosthetic Knee (ESPK) -our first product- has enabled above knee amputees around the world to do things that Jarem was told would never be possible when he faced his own amputation in 1994. Thousands of new amputees have been told the same thing until the XT9 became available.

The XT9 has truly become one of the most revolutionary advances in amputee ability in several decades! In the time that Jarem Frye has been an amputee, amputees have gone from being able to walk smoothly to being able to run and now, being able to snowboard, surf, ski, climb, skate, wakeboard, scuba, and much more thanks to XT9 ESPK.

Our goal as a company is not merely to sell a product, but to sell the dream of true ability to every amputee we come across, and to create the devices that make the dream a reality. We want to show the world that amputees can do whatever they put their minds to and we want to provide the devices you need to make your own “impossible” a reality.

Our clients have truly made this “the revolution in prosthetics” by accomplishing the impossible all around the world! The accomplishments include the world’s first competitive AKA snowboarder -Nicole Roundy who despite being told that snowboarding was out of the question, has used the XT9 ESPK to win an impressive list of gold, silver and bronze medals in national and international slope-style snowboard competitions. EJ Poplawski has become the first AKA alpine ski racer to compete on a prosthetic leg using the XT9 ESPK to work his way to a nation level of competition in his first season racing as an amputee. Garrett Jones amazed everyone by learning to “snowboard before he could even walk” after loosing his leg to an IED attack in the war on Iraq. After proving that anyone with enough determination could use the XT9 ESPK, even with only a six inch residual limb, Garrett became the first US Marine to return to active duty in a war zone when he accompanied his unit to Afghanistan for their second tour of duty.

With only a few years on the market, the XT9 ESPK has become a key aspect of many competitive winnings around the globe, impossible accomplishments and wonderful mind shifts in what is possible for amputees.

We are committed to continuing this kind of accomplishment by reaching out to mindsets and real life situations through our products, our marketing and our clients accomplishments!
