Abstract:
1. An auto-flex knee brace comprising: an upper thigh cuff positioned substantially above knee for encircling an upper part of leg of a user; a lower thigh cuff positioned substantially below the knee for encircling a lower part of the leg of the user; a flexible strap arrangement having a first strap means attached to a hinged retainer on the upper thigh cuff and a second strap means attached to a hinged retainer on the lower thigh cuff; and at least one spring column assembly releasably coupling the upper thigh cuff and the lower thigh cuff, each of the spring column assembly comprising: whereby the extension spring acts as a flexible hinge and the at least one spring column assembly is configured to mount at different relative vertical positions and modes between the upper thigh cuffs and the lower thigh cuffs thereby achieving a surgery-free way of promoting autogenously as well as supplement-induced knee cartilage cell production in a non-bone-scraping environment.
