In order to provide affordable and sustainable prosthetic solutions, LIMBS:
In addition to ISO test standards, LIMBS uses four different field tests to evaluate patient outcomes - Physiological Cost Index (PCI), a timed walk test, a GAITRiteTM test and the LIMBS lower limb Functional Parameters Questionnaire (FPQ). The data collected from that program has helped inform design revisions to the knee and make it better suited to meet the needs of patients. Initial test results have shown that compared to other available knees, the LIMBS Relief Knee enables a more normal gait pattern and easier swing through without significant loss of stability. Results from the patient outcomes measurements were presented at the ISPO World Congress in Leipzig, Germany. LIMBS manufactures its knee for distribution to clinics and international organizations. Additionally, LIMBS partners with qualified prosthetic companies to provide components for secondary devices, such as “aqua limbs,” in developed nations. Any/all monies generated from such sales are reinvested into the LIMBS program. |
Evolution of the LIMBS Knee
LIMBS Knees (2004-2019)
The New LIMBS Knee
The LIMBS Knee is a great achievement in prosthetics engineering. Since 2004, the LIMBS patented polycentric knee has evolved from a simple joint (that could be manufactured abroad using basic tools) to a highly sophisticated, injection-molded device.
The new LIMBS Knee is stronger, more stable and sleeker than previous generations. There is a greater emphasis on aesthetics, including a protective kneecap that will look more natural under a patient’s clothing and make it easier to kneel.
To evaluate its strength, LIMBS placed the knee under extreme loading conditions and implemented flexion tests. In comparison to other available knees, patients stated it has easier swing-through without significant loss of stability, a more normal gait pattern, lower energy expenditure, and more comfortable sitting and standing.
The new injection molding process can produce thousands of knees every year. Currently, the knees are manufactured and assembled in Mexico using both U.S. and globally-sourced components/materials. Soon, these knees will be distributed around the world to meet the enormous demand for low-cost and reliable prosthetic devices.

Latest Research
A REMARKABLE DEVELOPMENT IN LOW COST PROSTHETIC TECHNOLOGY
LIMBS new Executive Director and PhD. candidate, Lucas Galey, has published a paper in the peer-reviewed journal, Prosthesis, which describes his low-cost smart-knee, dubbed the "E-Knee." Galey offers proof of concept that "a prototype microprocessor knee can be manufactured for less than $1,000 with comparable stability and user experience to a standard high end device." Galey has been working on the experimental leg system since his undergraduate days. The project is an outgrowth of Galey’s long-term involvement with LIMBS. Click HERE to read the article.
