The LHC-08KJ Four Bar Mechanical Knee Joint utilizes a polycentric linkage design to offer superior geometric stability during the stance phase of walking. This ‘four-bar’ configuration creates an instantaneous center of rotation that stays posterior to the load line, providing a natural safety lock that prevents the knee from buckling involuntarily. It is an excellent choice for users who prioritize safety and stability on varied surfaces.

Manufactured from medical-grade Aluminium, this joint provides the necessary structural integrity for daily ambulation without adding excessive weight to the prosthetic build. The polycentric motion also facilitates better toe clearance during the swing phase by effectively shortening the prosthesis as it flexes. Rated for a 100kg load capacity, the LHC-08KJ is a dependable and high-durability option for transtibial and transfemoral applications requiring polycentric kinematics.
