Robolimb Prosthetics & Orthotics Clinic

An above-knee prosthesis with a mechanical knee joint is an artificial limb designed for individuals who have undergone transfemoral (above-knee) amputation. This prosthesis replaces the missing portion of the leg, including the knee joint, and allows the user to walk, sit, and perform daily activities. It consists of several components: a socket (which fits over the residual limb), a pylon (connecting rod), a mechanical knee joint, and a foot. The mechanical knee joint is the key functional part, allowing controlled flexion and extension for walking. Various types of mechanical knees are available, such as single-axis, polycentric, or weight-activated stance control, depending on the user’s needs and activity level. The prosthesis is often customized for comfort, stability, and mobility. Proper alignment and fitting are essential for function and gait. Regular rehabilitation and physiotherapy help the user adapt and improve mobility.
