SPORTS KNEE
3S80
The 3S80 Fitness features optimal swing phase control for running. Even at high stride rates, smooth extension is ensured by extension damping throughout the entire extension movement, increasing gently just before reaching the end position. Flexion and extension damping can be adjusted separately.

The larger flexion angle for jogging and sprinting is precisely controlled by flexion damping.

Selecting the appropriate prosthetic knee unit for the transfemoral amputee (above knee) is important to achieve a successful outcome and should be based on the person’s activity level, lifestyle and general health. The latest advanced knee is not necessarily the best choice for everyone. Safety and stability for some amputees are more important than functional performance. More active amputees prefer a knee that will give them a higher level of function even if it requires greater control.
