Quick answer: A knee scooter (knee walker) lets you rest the injured leg on a padded platform and roll on your good leg after foot or ankle surgery. Most models hold 250-350 lb and weigh 19-26 lb. They need good balance: in one 2023 study, 37% of users fell at least once. If balance is a concern, a walker or wheelchair is often safer.
Our 3 quick picks
- Best budget pick: KneeRover Economy (300 lb, 21 lb, user height 4’9″ to 6’4″).
- Best for outdoors: All Terrain KneeRover (350 lb, three 12-inch air-filled tires).
- Best for shorter users: Roscoe Economy ROS-KS2 (knee pad from 13.75 in, user height from 4’11”).

Is a knee scooter safe for seniors?
It can be, for an older adult who is otherwise strong, active and steady. A knee scooter asks a lot: you balance on one leg, steer, and brake with your hands at the same time.
A 2023 prospective study in the Journal of Orthopaedic Surgery and Research followed 118 patients who used a knee scooter after foot or ankle surgery. 37% fell at least once and 15% were injured. Of those injured, almost all said their recovery took longer, by about 7 weeks on average. A sedentary lifestyle was the only risk factor found (about 4.7 times the odds of injury). The patients’ average age was 48, so results for people in their 70s and 80s may be different.
Still, 92% of users said they would use a knee scooter again. The takeaway: it is a good tool for the right person, and the wrong tool for someone with poor balance.
Who a knee scooter is NOT for
- People who already use a walker for balance, or who have fallen in the past year. Take the 4-Stage Balance Test with a helper, or read our fall risk assessment guide, and talk to your care team.
- Anyone who cannot stand on the good leg for a minute or two without support.
- People with weak hands or arthritis that makes squeezing brake levers hard.
- Homes with stairs you must use every day. Knee scooters are not for stairs.
- Injuries above the knee, or a knee that cannot bend to rest on the pad.
For these users, a walker used with a no-weight-bearing hop, or a wheelchair for longer distances, is usually safer. A caregiver can add a gait belt for transfers.

How do you fit a knee scooter?
- Stand on your good leg in the shoes you will wear.
- Set the knee pad so the injured leg’s knee rests on it with your hips level and the foot lifted off the floor.
- Set the handlebar so your elbows bend slightly, similar to walker height.
- Squeeze both brakes and lock the parking brake before you get on or off.
- Practice inside, with a helper, on a flat floor before going outside.
Always follow the maker’s fitting guide and your surgeon’s weight-bearing orders.
Does Medicare pay for a knee scooter?
Often not. Medicare bills knee scooters as HCPCS code E0118 (“crutch substitute, lower leg platform”). A Medicare DME contractor article said coverage “remains denied” for E0118 because of limited evidence in the Medicare population; that article was retired in September 2025, and no clear new coverage rule replaced it. Ask your plan before you buy. Some Medicare Advantage and private plans do cover them, and many medical-supply stores rent knee scooters for a few weeks. See our Medicare guide for walkers and rollators.
Safety tips for using a knee scooter
- Clear rugs and cords; wear a non-slip shoe on the good foot.
- Go slowly and brake before turns. Do not coast down ramps.
- Never use it on stairs or curbs. Have someone help with steps.
- Keep loads light; a small basket beats a heavy bag on the handlebar.
- In the bathroom, sit for showers; a tub transfer bench avoids stepping over the tub.
Knee scooter FAQ
Is a knee scooter better than crutches for seniors?
For many older adults, yes, because crutches need strong arms and good balance. But knee scooters also need balance on one leg. If you are unsteady, a walker or wheelchair may be safer.
How much weight can a knee scooter hold?
Most hold 250-350 lb. In our list, the Roscoe Economy holds 250 lb, the KneeRover Economy 300 lb, and the rest 350 lb.
Can you use a knee scooter on stairs?
No. Knee scooters are for flat ground only. Use a stair rail and help, or a different plan, for stairs.
Does Medicare cover a knee scooter?
Usually not under Original Medicare (code E0118 has been denied in contractor guidance). Some private and Medicare Advantage plans cover them. Renting is a common low-cost option.
What height should a knee scooter be?
The knee pad should let your injured leg rest with your hips level while you stand on your good leg, and the handlebar should allow a slight elbow bend.
If standing on one leg is not safe and a helper can push, a transport chair may be the better short-term option. Compare models in our best transport chairs for seniors guide.
