LegWorks Is Expanding Access to High-Function Prosthetics Through Engineering and New Economics

For many amputees, the most rigid barrier to walking again is not rehabilitation, affordability, durability, and access to technology that works reliably in everyday life.

LegWorks, a Buffalo-based medical device company, is tackling this challenge with a model built on practical engineering and sustainable economics. Operating as a for-profit social enterprise, the company develops high-functioning prosthetic knees that deliver performance without the extreme pricing typical of premium systems.

Its All-Terrain Knee portfolio prioritizes advanced mechanical design over complex electronics. The result is rugged equipment that is easier to maintain and capable of operating in environments where technical support or charging infrastructure may be limited.

Two core innovations define the approach. The AutoLock mechanism enhances stability during weight bearing, helping prevent unexpected buckling and reducing fall risk. The Variable Cadence Controller adapts across walking speeds, enabling smoother, more natural movement with lower energy expenditure.

LegWorks pairs technology with a dual-market strategy. In higher-income regions, lower prices expand options for underinsured patients. Globally, partnerships with NGOs and clinics enable subsidized distribution, linking commercial growth directly to broader mobility access.

The company is advancing a straightforward proposition: prosthetic innovation can be high performing, affordable, and scalable at the same time.

LegWorks is not only redesigning knees. It is redesigning who gets to move.
