Unfortunately, knee walkers are not normally paid for by Medicare. If you can get a doctor's prescription saying that crutches or canes will not provide the support needed, it may be possible for Medicare Part B to cover a knee walker. However, providers of knee walkers generally state that Medicare does not cover this type of walker at this point in time, and under most circumstances.
Update: As far as I know, it is still necessary to get a doctor's prescription to get Medicare coverage under Part B for a knee walker. Whether it is easier now to be approved for a knee walked, I don't know.
