The present invention involves a garment for enveloping at least in part a joint, for example a knee of a leg. Comprising a belt disposed to fit about a body part, for example the waist, of the user, a plurality of inextensible web portions and a tension member are disposed longitudinally along a corresponding predetermined curved three-dimensional spatial path within or on a matrix of a garment fabric along the leg. The path spatially relates the first tension member to at least one natural ligament of the knee, at least one of the plurality of inextensible web portions being disposed to apply pressure to the medial side of the knee. The tension member is anchored by the triceps surae of the leg and to the belt via a tensioner. A second tension member may be incorporated in the garment leg to apply pressure to the lateral side of the knee.
