I used this device pre and post hip surgery. Would be useful for anyone with hip or knee pain or back issues. $30 including tax at amazon Designed to bring efficient support to anyone with mobility limitations. Even without the use of both hands, this product will bring back the simplicity of wearing socks. They are on in one simple step and off with another. Suitable for putting on and taking off all kinds of socks, including nylons and light compression stockings.
