In orthopedics, a<unk>  is a term for the inward angulation of the distal segment of a bone or joint.  The opposite of<unk>  is called valgus.
The terms<unk>  and valgus always refer to the direction that the distal segment of the joint points.
For example, in a<unk>  of the knee, the distal part of the leg below the knee is deviated inward, resulting in a bowlegged appearance.  Conversely, a valgus<unk>  at the knee results in a knock-kneed appearance, with the distal part of the leg deviated outward.
