Knee scooters
Ask your surgical team before buying a knee scooter — it's built for a foot or ankle injury, not a knee that's the surgical site itself. If they clear it, get the standard steerable model below; step up to the all-terrain version only if you'll actually be rolling over gravel, grass, or a driveway. Renting almost always beats buying for a typical 2–6 week recovery.
The two Medline picks are on Medicare's own E0118 product classification list; the Roscoe pick has not been checked against that list yet. All three are checked against CPSC/FDA recall data — how we choose →

Medline All-Terrain Knee Walker, 10" Pneumatic Tires
$199.99 Amazon price, checked Oct 25, 2026
- Weight capacity: 350 lb.
- Wheels: 10-inch pneumatic (air-filled) tires
- HCPCS reference: E0118 (crutch substitute, lower leg platform, with or without wheels)
Same 350 lb. rating as the standard pick, with air-filled tires for gravel or grass.
Best for: rolling over gravel, grass, or an uneven driveway rather than flat indoor floors.
Same 350 lb. weight rating as the standard pick, but air-filled 10" tires instead of hard casters -- the upgrade that's worth the extra cost only if you're rolling over gravel, grass, or an uneven driveway rather than flat indoor floors.
Flaw: A wheel upgrade most people, on flat indoor floors, will never actually use.

Medline Economy Knee Walker, 8" Wheels
$115.84 Amazon price, checked Oct 25, 2026
- Weight capacity: 350 lb.
- Wheels: four 8-inch wheels
- HCPCS reference: E0118 (crutch substitute, lower leg platform, with or without wheels)
A 4-wheel knee scooter on Medicare's product classification list, with no basket or premium finish. Today it is the lowest-priced of our three picks.
Best for: keeping cost down when you don’t need a basket or a premium finish.
Same manufacturer and 350 lb. weight rating as the all-terrain pick above, no basket or premium frame finish -- a full-size 4-wheel knee scooter that is on Medicare's product classification list (Palmetto GBA DMECS) under Medline's own listing.
Flaw: No basket and a plainer frame finish than the all-terrain pick, for the same manufacturer and weight rating.
See the Medline Economy Knee Walker on Amazon →Fitment: height, weight capacity, and steering
- Weight capacity: all three picks above are rated to 350 lb. — check that number against the actual person, since it's a structural spec on a rolling frame, not a suggestion.
- Height range: the standard steerable pick has adjustable handlebars and knee-pad height, but its listing doesn't give the ranges. Check the size chart on whichever listing you're buying.
- Steering: the standard pick has a steerable front for tight turns indoors — the point in a bathroom or narrow hallway.
Weight caps and wheel specs above are pulled directly from each product's own Amazon listing — Medicare's fee-schedule and utilization data don't include product specs, only the coverage facts below.
When a knee scooter is the wrong choice
Knee scooters are designed for a lower-leg, foot, or ankle injury: the injured leg's knee rests on the padded platform, and you push and steer with the other leg. After a knee replacement, at least one knee is the surgical site itself — resting weight on a rolling platform is a different demand than standing behind a walker, so confirm with your surgical team whether that's something they want during your specific recovery window.
There's also a balance and coordination demand a stationary walker or rollator doesn't have: you're steering and braking with your hands while your weight is on one leg and a platform that rolls. If balance, coordination, or grip strength is a real concern, a walker (already covered with a prescription — see the checklist) is the steadier default. That mismatch is why this site's own checklist flags a knee scooter as optional, not standard, for knee replacement specifically.
What Medicare actually pays
Knee scooters have no dedicated HCPCS code. The closest match, E0118 ("crutch substitute, lower leg platform, with or without wheels"), has zero entries in the Medicare DMEPOS fee schedule and zero national claims in 2024.
CMS's own policy article describes the code as covering either a strap-on lower-leg platform or a wheeled platform device the beneficiary propels with the sound limb — so a knee scooter fits the code's description, it just isn't a benefit Medicare pays toward. In practice this is a cash purchase or a short-term rental, not something billed to Medicare with a prescription.
Recall history
FDA has recorded 2 distinct knee-walker safety events: a 2012 Invacare/Kenstone Metal knee walker (rod supporting the knee pad could break or bend under load, risking a collapse) and a 2024 Medical Depot "Nitro Glide" knee walker, still open (the tiller can separate from the base/caster assembly, risking a fall).
The 2024 event alone appears as 3 separate records — one general device-recall entry plus a matching enforcement-classification entry for each of its two color variants (blue and red) — so FDA lists 4 total records for these 2 real-world actions. The 2012 event is resolved (status: Terminated); the 2024 event is not (status: Open/Ongoing, FDA Class II). Neither recall record mentions a reported death. CPSC's consumer-recall database returned no records naming a knee walker for the same searches — this looks like an FDA-medical-device-regulated recall history with no separate CPSC consumer-product action, not a gap in our search.
None of the three picks above (Roscoe Medical, Medline) match either recalled brand or model. Roscoe Medical does appear in that data, for a 2014 recall of a transport rollator whose caster could come off — a different product, not a knee scooter. We searched federal recall databases using general terms like walker, rollator, shower chair, and bed rail — there's no dedicated "knee scooter" search, so the 2 events above surfaced incidentally, not from an exhaustive knee-scooter-specific search. Before buying secondhand or accepting a hand-me-down, check the exact brand and model yourself at CPSC's public recall search and FDA's device recall database — especially the hand brake, tires, and steering lock, per the borrowing checklist.
Rent or buy?
These three picks run $115.84–$199.99 to buy outright on Amazon today. For a typical 2–6 week recovery, renting usually beats buying — see rent vs. buy: knee scooter, ice machine, hospital bed for the full break-even math against real rental rates.
