The LHC-KJ-PKD-03 Polycentric Knee Joint is specifically optimized for knee disarticulation amputees, where preserving the long residual limb length is a primary concern. The low-profile polycentric design allows the joint to be positioned closer to the distal end of the socket, ensuring that the prosthetic knee center aligns correctly with the user’s sound limb. This helps in maintaining a balanced appearance and an efficient walking gait.

By utilizing a high-tensile Stainless Steel construction, this joint supports a broad range of user weights up to 120kg. The polycentric linkage provides inherent stance stability and improves toe clearance during the swing phase, which is crucial for the high-leverage forces associated with long residual limbs. It is an essential component for clinicians seeking to provide knee disarticulation patients with a stable, high-strength, and anatomically appropriate prosthetic solution.
