Knee walker

I have seen all types of mobility devices in recent years, but up to now I had never seen a knee walker. Thankfully, I have never needed one either, but never say never...
A knee-walker is apparently a replacement for the antique idea of needing crutches and hobbling around like a land-locked pirate.. and when you look at the device, although at first it might seem a little unwieldy, I have to admit that this has to be a lot better than sticking lumps of wood under your arms and swinging drunkenly around the place.

These devices are becoming increasingly sophisticated with a basket to carry a few knick-knacks, a comfortable-looking 'seat' for your knee, and even brakes for when you get a bit ahead of yourself. Some are collapsible and lightweight, ideal for a quick shopping trip.
