Valgus knee or knock knee is a lower leg deformity that exists when the bone at the knee joint is angled out and away from the body's midline. This deformity is defined as a valgus angle equal to or greater than 10°[1]

The bone deformity is often as the result :

  • lateral femoral condyle deficiency with external rotation deformity of the tibia and lateral tibial plateau deficiency as well.
  • The patellofemoral joint can be affected with lateral subluxation of the patella and trochlear blunting secondary to lateral femoral condylar wear.
