Joshi

Modular Prosthetic Limb System

A Leg To Stand On’s Joshi (pronounced Joe-she) is a thoughtfully designed, aluminum modular prosthetic lower limb system. Named in honor of our pioneer prosthetist Dhiren Joshi, the Joshi provides more affordable and sustainable prosthetic solutions - thereby increasing the accessibility, quality, and modernization of prosthetic limbs in low and middle income countries.

Featuring a sleek and minimal design with a smooth aesthetic, the Joshi utilizes lightweight aluminum technology. It serves as a mobility aid our CoolKids are proud to use, improving self-esteem, combating social stigma, and offering them the opportunity to pursue their dreams.

ISO 9001: 2015 and ISO 13485: 2016/NS-EN ISO 13485: 2016 Certified // CE Pending

Joshi components and third-party accessories are only available with ALTSO partnership.
