For transfemoral amputees, a precise socket fit is critical for comfort and mobility—but residual limb volume changes (RLVC) can disrupt that fit daily. The CJ Socket, a groundbreaking design from CJ Socket Technologies, tackles this challenge with user-controlled adjustability, transforming the prosthetic experience. Unlike rigid traditional sockets, the CJ Socket combines a J-shaped rigid frame (covering the front half of the thigh) with a flexible, non-elastic “Sail” textile at the back, secured by an adjustable closure.
This innovation lets patients fine-tune their socket’s fit instantly—tightening or loosening it as their limb swells or shrinks. No more adding socks or waiting for a new socket; the wearer maintains skeletal control and hydrostatic lift with a simple adjustment. At Precision Prosthetics, we’ve seen patients regain independence with this system. A 58-year-old transfemoral amputee, for example, now adjusts her socket mid-day to stay comfortable during long walks. The CJ Socket’s lightweight design—half the weight and heat of conventional sockets—further boosts wear time, while its fabric back conforms naturally when sitting. For amputees, this means less hassle and more control over their mobility, making the CJ Socket a true game-changer in prosthetic care.
