Patients are able to move more naturally with hydraulic prosthetic knee joints. Regaining mobility is a top priority for patients who have lost a leg.
However, the development of more natural-looking prosthetic limbs and joints has come a long way from the common conception of the hook hand and peg leg.
Due to its high flexion resistance, the hydraulic knee joint is a monocentric joint with a rotary hydraulic system that controls the swing phase and provides support in the stance phase.
These units are made up of pneumatic or hydraulic cylinders with pistons inside. When the knee is flexed, pneumatic control compresses air, stores energy, and then returns that energy when the knee is extended. A spring coil can be added to improve gait control even more.
By responding to varying walking speeds, pneumatic (air) and hydraulic (fluid) systems mimic the muscles of the natural knee.
Hydraulic knees are typically heavier than pneumatic knees because they require fluid, but they can also provide a smoother walking pattern across a wider range of speeds.
There are two types of prosthetic knees: mechanical and computerized. There are three types of mechanical knees: polycentric, single-axis, and multi-axis. The features of each prosthesis are chosen in accordance with the user’s needs.
The Global Hydraulic Prosthetic Knee Joints Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
A hudraulic prosthetic knee with waterproof legwork is discharged. LegWorks, Inc., based in Buffalo, New York, is making life better and more fun for amputees who are super active.
The ATK HydraPro is a waterproof, highly functional hydraulic prosthetic that the company has made available. It lets amputees walk at different speeds on any terrain. The company has five prosthetics.
The patented AutoLock Technology from LegWorks is used in the ATK HydraPro. This technology encourages proper gait patterns and provides excellent stability for the user, even in the most challenging terrain.
Additionally, it has a novel swing-phase control system that enables smooth and optimized gait patterns by combining hydraulics and LegWorks’ Variable Cadence Controller, which is the subject of a patent application. In comparison to conventional designs, the AutoLock Technology provides superior stability.
A more natural and energy-efficient stride is produced when the knee remains securely locked until the late stance phase, when it is disengaged for an effortless swing phase initiation.
According to decreased swing-phase initiation effort is associated with more normal walking patterns and lower energy consumption during walking.
This is essential for amputees not only to enable them to walk greater distances without becoming exhausted but also to assist in the maintenance of musculoskeletal health.
The ATK HydraPro is our most advanced and best-functioning knee joint, providing amputees who are highly active and demanding with the next level of performance.
