Quick answer: A knee scooter lets you rest the injured leg on a padded platform and push along with the good one, so your hands are free of crutches. It suits a below-the-knee injury, such as a broken ankle or foot surgery, where you have been told not to put weight on that foot. It is not suitable for knee injuries, for anyone with poor balance, or for anyone who cannot stand on one leg for a while. Choose a steerable model with a hand brake, check the pad adjusts to the height of your knee, and check the weight limit. Ask your surgeon or physiotherapist before using one.

Who a knee scooter suits
Knee scooters work best for a few weeks of non-weight-bearing recovery after an ankle fracture, Achilles injury, bunion surgery or a foot wound. They are faster and less tiring than crutches on flat ground, and you can carry a drink or a bag in the basket.
They are the wrong choice if the injury is at or above the knee, if kneeling on that knee is painful, or if dizziness or weakness makes balancing on one leg risky. Crutches or a walking frame are safer in those cases. The NHS usually supplies crutches or a frame rather than a knee scooter, so most people buy or hire one.
How to choose a knee scooter
Steering and brakes
A steerable front makes turning in a kitchen or hallway far easier than a fixed frame. Look for a hand brake you can squeeze firmly, and a parking lock so the scooter stays put while you get on and off.
Pad height and handlebar height
With the injured knee on the pad, your thigh should be roughly level and your standing leg slightly bent. The handlebar should sit around hip height. Both need to adjust far enough for your height.
Wheels
Smaller solid wheels suit smooth floors indoors. Larger or pneumatic wheels cope better with pavements, gravel and dropped kerbs, but add weight.
Folding and weight
If it needs to go in a car, check the folded size and whether someone can lift it for you. Check the maximum user weight as well, and choose a model rated comfortably above yours.
Using a knee scooter safely
- Practise indoors first, with someone nearby, before going outside.
- Clear rugs, cables and clutter from the route you use most.
- Never use it on stairs. Go up and down on your bottom or use crutches as your physiotherapist showed you.
- Brake before you stop, and apply the parking lock before you step off.
- Keep the injured leg on the pad. Do not let the foot drop to the floor for balance.
Buy or hire?
Most people need a knee scooter for six to eight weeks, sometimes longer. Hiring can make sense for a short recovery, and some hire companies deliver. Buying is often similar in cost for anything longer, and a scooter in good condition can be sold on afterwards.

Frequently asked questions
What is a knee scooter used for?
It is used by people who must keep weight off one foot or ankle, usually after a fracture, surgery or wound. You kneel the injured leg on a padded platform and push with the other leg.
Is a knee scooter better than crutches?
On flat ground it is usually easier and less tiring, and it leaves your hands free. Crutches are better on stairs, in tight spaces and for injuries at or above the knee. Many people use both.
Can I get a knee scooter on the NHS?
It is not common. The NHS usually supplies crutches or a walking frame. Ask your fracture clinic or physiotherapist, and if one is not available, buying or hiring is the usual route.
Can I use a knee scooter with a knee injury?
No. The scooter puts your weight through the injured leg’s knee, so it is only suitable for injuries below the knee. Speak to your clinician if you are unsure.
Are knee scooters safe outdoors?
They can be on smooth, level pavements, especially models with larger wheels. Take care on slopes, kerbs, wet leaves and gravel, and always use the brake when going downhill.
How do I adjust a knee scooter to the right height?
With your injured knee on the pad, your thigh should be roughly level with the floor and your standing knee slightly bent. Set the handlebar at about hip height so your arms are relaxed.
