Abstract

In this paper, we introduce an academic-level, highly modular leg prosthesis based upon the Open Source Leg (OSL) 2.0, targeting improved manufacturability, cost-effectiveness, and functionality in prosthetic technology. The OSL’s structure has been amended by implementing a modular design and more standard components to support flexible configurations for both left and right leg amputations. With respect to the OSL 2.0, our results demonstrate a 40-70% reduction in manufacturing time and costs while maintaining high standards of safety and functionality as confirmed by Finite Element Analysis (FEA), which showed an enhanced safety factor of 1.107 under static loads. The new prosthetic leg achieves a significant cost reduction and facilitates greater accessibility and adaptability, promoting further adoption.
