Knee Joint

Microprocessor-controlled Knee Joint

• Uses a microprocessor to automatically adjust movement direction and walking speed according to the user’s environment, providing immediate response to changes.
• Using an app, the prosthesis can be easily controlled, allowing the user to conveniently adjust it according to their level of activity and lifestyle.

Hydraulic Knee Joint

• Utilizes the flow of hydraulic fluid (silicone oil) inside the knee joint to control walking speed, stability, and balance during the stance and swing phases, enabling a natural gait.
• Unlike microprocessor-controlled knees, it does not have an automatic self-adjusting function.

Pneumatic Knee Joint

• Uses the flow of air within pneumatic cylinders inside the knee joint to regulate walking speed, stability, and balance during stance and swing phases for a natural gait.

Mechanical Knee Joint

• Composed of a four-bar linkage structure. When the knee bends, the length of the lower leg shortens, helping to improve ground clearance.
• Unlike microprocessor-controlled knees, it does not have an automatic self-adjusting function.
