Advanced Features

SS304 Stainless Steel Construction

Manufactured from SS304 stainless steel, the knee joint provides excellent structural strength and corrosion resistance for long-term everyday use.

Zero-Play Construction

The precision-engineered zero-play construction helps maintain stable and controlled knee movement while supporting consistent mechanical performance.

Soft-Close Return Mechanism

The integrated soft-close return mechanism helps minimise jerking during knee extension, providing smoother and more controlled movement throughout the walking cycle.

Dual Cushioning System

A dual cushioning system helps absorb impact during walking, contributing to improved comfort and smoother knee movement.

PTFE Washers

PTFE washers reduce friction between moving components, helping promote smooth articulation and minimise wear over time.

Up to 165° Flexion

The knee joint provides up to 165° of flexion, allowing a wide range of movement for daily activities such as walking, sitting, and transitioning between positions.

Corrosion-Resistant Design

The stainless steel construction offers excellent resistance to corrosion, making the knee joint suitable for long-term everyday use.

Tested for Reliability

The Polycentric Mechanical Knee Joint Stainless Steel has been tested according to ISO 10328:2016, demonstrating compliance with internationally recognised structural testing requirements for lower limb prosthetic components.
