A knee scooter or knee walker is a four-wheeled alternative to crutches or a traditional walker as mobility aid. Today’s version is a lightweight, foldable design that, with the knee flexed, supports the shin of the unusable limb.

The knee walker is a safe, comfortable, and easy-to-maneuver alternative to the traditional crutch. The knee walker is foldable and suitable for transport in the boot of a car.
