“…A significant amount of research and development is conducted both in engineering and medical considering various design, materials and fabrication process to achieve better functioning of transfemoral (TF) prosthetic components. 1 The knee joint is probably the complicated unit in a TF prosthesis. Prosthetic knees have seen substantial development throughout time, moving from simple hinges to knees that can be powered.…”

“…The weight 18 of a prosthesis may induce unwanted muscular effort, resulting in increased energy consumption. Amputees with higher level physical activities need materials with high strength 1,18,19 . Polymer matrix composites (PMC) are sturdy and lightweight materials which can be replaced in place of metals where a lighter weight and higher strength is required.…”

“…Amputees with higher level physical activities need materials with high strength. 1,18,19 Polymer matrix composites (PMC) are sturdy and lightweight materials which can be replaced in place of metals where a lighter weight and higher strength is required. In reality, the majority of earlier research focuses on the design, analysis and fabrication of composite socket 20,21 components and the majority of highend commercial foot prosthesis 22 are manufactured using carbon fibre reinforced polymers (CFRP) composites [23][24][25] for their superior mechanical properties.…”

A prosthetic knee is designed to replace the functionality of an anatomical knee in transfemoral amputees. The purpose of a prosthetic knee is to restore mobility and compensate amputees for their impairment. In the present research numerical modelling and simulation of a carbon fabric reinforced polymer made polycentric prosthetic knee with four‐bar mechanism was performed. Virtual prototyping with computer‐aided design and computer‐aided engineering software ensured geometric and structural stability of the knee design. The linkage mechanism, instantaneous centre's location and trajectory were investigated using multibody dynamics and analytical formulations. Computational simulations with a non‐linear finite element model were employed with joints, contact formulations and an orthotropic material model to predict the displacement, stress formulated and life of the knee prosthesis under static and cyclic loading conditions. Finite element analysis assessed the strength and durability of knee in accordance to standards. Maximum Principal stress of 155 MPa and life expectancy of 3.1 × 106 cycles were determined for the composite knee through numerical simulations ensuring a safe design. Experimental testing was also conducted as per standards and the percentage error was estimated to be 2.52%, thereby establishing the validity of the finite element model deployed. This type of simulation‐based approach can be implemented to efficiently and affordably design and prototype a prosthetic knee with desired functioning criteria.

“…[ 4 ] These composite materials have high strength compared to those of the monolithic materials and they also offer excellent biocompatibility. Shank tube [ 5 ] often acts as connecting member between a prosthetic knee or a socket and a foot. The traditionally used prosthetic shank tube is generally made of lightweight metal such as aluminum, titanium, stainless steel, or an alloy of the above‐mentioned materials.…”

Globally, the most prevalent reasons of lower extremity amputation are diabetes, peripheral vascular disease, trauma, tumors and congenital abnormalities. Though modern lower limb prosthetic devices are available in the market, affordability for amputees in developing and underdeveloped nations is a concern, so it is required to make it more accessible with more economical options. This research is an initiative to develop a composite shank tube by filament winding technique as an alternative to conventional metallic tubes for prosthetic components. The composite materials used for this study included glass fiber/epoxy and hybrid fiber (glass + carbon)/epoxy. The composite tubes were manually fabricated and were subjected to axial compression test to estimate the loading bearing and energy absorption capacities. The composite's material properties were determined as per ASTM standards. The obtained properties and experimental data were used to carry out simulations for the composite tubes with ANSYS ® 2021 software package under quasistatic loading conditions. Based on the research that was done, the overall performance of Hybrid Fiber tube in terms of peak loads and energy absorption indexes looks good, and there is a high possibility that they could be used as a loadbearing part in a lower limb prosthetic system.
