Frequently Asked Questions

What's the difference between a knee rollator and a hands-free knee crutch?
A knee rollator, like the BIOS 4-Wheel Knee Rollator, uses wheels and a padded platform to support the injured leg while the user pushes it along like a walker. A hands-free knee crutch, like the iWALK3.0, straps directly to the thigh and lower leg, allowing the user to walk without wheels and with both hands completely free.

Who should use a knee walker instead of crutches?
Knee walkers are designed for individuals with non-weight-bearing restrictions due to foot, ankle, or lower leg injuries, fractures, or surgery. They offer a more comfortable option for those who find traditional underarm crutches tiring or uncomfortable.

Can I keep my hands free while using these devices?
The iWALK3.0 Hands-Free Knee Crutch is specifically designed to keep both hands free during use. The BIOS 4-Wheel Knee Rollator requires one or both hands on the handlebars for steering and braking.

What is the weight capacity of these devices?
The BIOS 4-Wheel Knee Rollator supports up to 300 lb (136 kg), while the iWALK3.0 supports up to 275 lb (125 kg).

Is assembly required?
The BIOS 4-Wheel Knee Rollator requires assembly. The iWALK3.0 comes with an instruction manual for proper fitting and adjustment.
