When choosing to fit a prosthesis , what struggles did you have?

As we all know, the prosthetic knee joint  is the most important accessory in the thigh prosthesis, so it is necessary to pay special attention and caution when choosing the assembly.

What is the difference between a hydraulic knee and a pneumatic knee? Are hydraulic joints more stable? Which one is more suitable? These questions will always confuse people to make choices

In the process of walking, the prosthetic knee joint first plays a role in supporting our body. But more importantly, the flexion function of the knee joint enables it to control the prosthetic limb to swing forward or backward, thus forming a complete gait cycle that supports the entire walking process.

The physiological knee joint can control the swing of the thigh softly and smoothly, and the air pressure or hydraulic system in the prosthetic knee joint also imitates the physiological knee joint and plays such a role.

Whether it is a pneumatic knee joint or a hydraulic knee joint, their working principle is to control the prosthesis with a solid line through the resistance formed by the piston movement of the cylinder to compress the air or push the hydraulic oil. Because of the different characteristics of these two media, their performance on prosthetic knee joint control is also different.
