A knee walker or rollator is suitable for those who cannot support one of their legs and need the help of a walking aid. It is used as a scooter, supporting the injured leg on the padded part and propelling itself with the healthy leg. It can also be used sitting, placing the injured leg in the front.
It is ideal for those who are recovering from surgery, fractures, sprains or foot ulcers. It does not require much effort and reduces the risk of falls.
