Abstract

Abstract There is disclosed a ready-to-wear pull-on knee support adapted to be placed over the knee, said support comprising a generally cylindrical body comprising a resilient flexible unitary sleeve, which is preferably formed from an elasticized fabric laminate. The elasticized fabric laminate includes an open-cell polymeric foam core, an outer surface comprising an elasticized fabric having a looped structure and an inner surface for wear next to the body, comprising an elasticized cotton fabric. The support includes integral parallel proximal and distal encircling straps adapted to encircle the lower thigh and upper calf, respectively, medial and lateral stabilizing or reinforcing straps and infinitely adjustable proximal and distal posterior closure means. A patella opening can be provided for patella support. A popliteal opening can be provided or the popliteal area may be covered, in which case the popliteal area is formed with a C-seam extending outwardly from the distal and proximal closure means over the outer popliteal area.
