What is axle friction on the prosthetic knee joint?

Axle friction in a prosthetic knee joint refers to the resistance encountered by the knee joint's moving parts as they rotate around the axle during flexion and extension. This friction can affect the smoothness of movement, stability, and overall functionality of the prosthetic limb. Proper management of axle friction is crucial for ensuring the knee joint mimics natural movement, enhancing user comfort and mobility. Adjustments may be made to optimize performance based on individual user needs and activity levels.
