The prosthetic knee joint is a vital component of prosthetic limbs for individuals who have undergone above-knee amputations. This review study assesses the modeling, analysis, and manufacturing of knee prostheses. Addressing the urgent requirement for efficient prosthetic solutions in response to the rising number of amputations. The study reviewed various types of mechanical passive prosthetic knee joints, including single-axis, polycentric, pneumatic, and hydraulic designs. The inspection and comparison of a microprocessor-controlled and powered knee joint were also carried out. To determine how much patient comfort improves while walking and performing other activities, and how the body stabilizes during activities or duties such as stair ascent and walking on an uneven surface.; the study found that many studies have focused on the progress of prosthetic knees, particularly those utilizing MP controls, in enhancing mobility, stability, and comfort. Enhancements in materials and design, facilitated by Finite Element Analysis (FEA), have proved transformative. The cost remains a practical constraint; therefore, research should focus on simplified and more affordable systems. The research indicates a need for further development in adjustable or custom-fit prosthetic knees, encompassing 3D-printed devices and lightweight materials. This review study recommends that further studies continue to develop various types of knee prostheses, aiming to design one that is less complex and more affordable for many clients, while also addressing the challenges that affect the development of prostheses
