Congenital dislocation of the knee: a review of four cases

ABSTRACT

Congenital dislocation of the knee [CDK] is a very rare condition, the incidence not being known with certainty. The etiology is also unknown. We reviewed four patients with severe CDK during the period of 1974-1986. The male/female ratio was 31. Three had bilateral and one unilateral dislocation. All were treated initially conservatively. Later three knees were operated upon. All treated knees have full range of movements except one which had secondary infection. The maximum follow up period [one case] is 12 years
