Common causes of valgus knee (genu valgum or "knock-knee") in adults include arthritis of the knee and traumatic injuries. Knee arthritis with valgus kneeRheumatoid knee commonly presents as valgus knee. Osteoarthritis knee may also sometimes present with valgus deformity though varus deformity is common. Total knee arthroplasty (TKA) to correct valgus deformity is surgically difficult and requires specialized implants called constrained condylar knees. Examples
TerminologyValgus is a term for outward angulation of the distal segment of a bone or joint. The opposite condition is called varus, which is a medial deviation of the distal bone. The terms varus and valgus always refer to the direction that the distal segment of the joint points. For a discussion of the etymology of these words, see the entry under varus. A mnemonic to remember the two deformities is that valgus contains an "L", for Lateral deviation. See also
