A leg support adapted to be secured to a leg includes an elongate strut having first and second segments, and a flexible middle segment located therebetween. The strut is arranged for securing to a posterior side of a leg and is centrally located along a medial-lateral plane of a leg. A resilient element is removably secured to a first surface of the strut, and extends across the middle strut segment. The middle strut segment and the resilient device are arranged to correspond to a knee of a leg and bend therewith such that the resilient device urges the strut into a generally upright configuration.

11. The leg support according to claim 9 , wherein the second end portion of the resilient device has a rotatable locking element permitting the resilient device to pivotally and removably connect to the second strut segment.
12. The leg support according to claim 9 , wherein the first receiving portion defines a bracket protruding outwardly from the first strut surface and arranged to receive the protruding portion of the resilient device.
13. The leg support according to claim 1 , wherein the resilient device is a polymeric spring element having a predefined configuration, the resilient device arranged for bending and resiliently returning to the predefined configuration.
14. The leg support according to claim 1 , wherein the resilient device has different stiffnesses located on first and second sides corresponding to lateral and medial aspects of a leg.
15. The leg support according to claim 14 , wherein the first resilient device side has a greater stiffness than the second resilient device side.
16. A leg support adapted to be secured to a leg, comprising:
an elongate strut having first and second rigid or semi-rigid segments, and a flexible middle segment located therebetween, the strut being arranged for securing to a posterior side of a leg generally and centrally located along a medial-lateral plane of a leg, and a second surface of the strut arranged adjacent the leg of the wearer; and
a monolithic polymeric resilient insert device removably secured against a first surface of the strut and extending across the middle strut segment, the resilient device having a predefined shape;
wherein upon bending due to a load, the resilient device urges the strut into a generally upright configuration corresponding to extension of a leg, the resilient device returning to the predefined shape after the load is released therefrom;
wherein the resilient device has a protruding portion located at a first end portion engaging a first receiving portion located on the first strut segment, a second end portion of the resilient device connecting to a second receiving portion located on the second strut segment.
