“…For the manufacturing of prostheses, material selection is very crucial. Various factors are considered for material selection, out of which strength, stiffness, and cost are among the most important ones [61,62]. Owing to the higher merits offered by biocomposites for the manufacturing of passive prostheses, the requirement is to reduce their cost by deriving them naturally and making them cost-effective [61].…”

“…This will ensure the provision of more biocompatible, biostable, and eco-friendly material for prosthesis, offering strength, stiffness, low maintenance, long life, durability, non-corrosive nature and high load endurance. In a comparison of aluminum, CFRP (carbon fiber-reinforced plastics), and GFRP (glass fiber-reinforced plastics), for polycentric prosthetic knee designs, CFRP showed the higher fatigue loads endurance, lighter weight, long life, and reduced replacement costs merits [62]. However, for an active transfemoral prosthesis, CFRP is not a favorite material owing to its poor electrical conductivity.…”

“…Normally different types of materials are used for manufacturing prosthetic knees for transfemoral amputees, including aluminum, titanium, biomaterials like fiber reinforced composites, glass fiber composites etc. [12,61,62]. The best composites for passive prosthetic limbs are Carbon fiber-reinforced polymer (CFRP) owing to the flexibility and reduced weight merits which combinedly offer comfort, higher strength and stiffness, as compared to other biomaterials [61].…”

“…These composites allow for energy storage to provide power to body for performing various actions. Polycentric prosthetic knee mechanism provides more comfortable and stable gait phases, as compared to single axis knee designs [62]. For the manufacturing of polycentric knee, three materials were compared: aluminum, CFRP (carbon fibre-reinforced plastics) and GFRP (glass fibre-reinforced plastics).…”

The aim of this review article is to appraise the design and functionality of above-knee prosthetic legs. So far, various transfemoral prosthetic legs are found to offer a stable gait to amputees but are limited to laboratories. The commercially available prosthetic legs are not reliable and comfortable enough to satisfy amputees. There is a dire need for creating a powered prosthetic knee joint that could address amputees’ requirements. To pinpoint the gap in transfemoral prosthetic legs, prosthetic knee unit model designs, control frameworks, kinematics, and gait evaluations are concentrated. Ambulation exercises, ground-level walking, running, and slope walking are considered to help identify research gaps and areas where existing prostheses can be ameliorated. The results show that above-knee amputees can more effectively manage their issues with the aid of an active prosthesis, capable of reliable gait. To accomplish the necessary control, closed loop controllers and volitional control are integral parts. Future studies should consider designing a transfemoral electromechanical prosthesis based on electromyographic (EMG) signals to better predict the amputee’s intent and control in accordance with that intent.
