ARAUJO, Luísa Neiva  e  ALMEIDA, Eduardo. Congenital dislocation of the knee: what approach? Review and experience of a pediatric hospital. Nascer e Crescer [online]. 2012, vol.21, n.1, pp.13-18. ISSN 0872-0754.

Background and objective: Congenital dislocation of the knee is a rare anomaly that includes a group of hyperextension deformities of the knee. Its incidence is about 1% of the developmental dysplasia of the hip. It is often associated with other musculoskeletal anomalies, the most common being the developmental dysplasia of the hip and clubfoot. In general, the diagnosis is established immediately after birth. Treatment can be conservative or surgical, and the first one usually results in better prognosis. The authors report their experience in the treatment of congenital dislocation of the knee and the favorable outcome in patients undergoing early reduction. Material and methods: A retrospective descriptive study was conducted based upon the analysis of medical records of patients diagnosed with congenital dislocation of the knee, treated at the Department of Pediatric Orthopedics of Hospital Maria Pia between 1990 and 2008. Results: Four patients with congenital dislocation of the knee are presented: three treated by conservative methods and one that required surgery. Discussion and conclusions: The authors highlight the importance of early reduction of congenital dislocation of the knee in the first hours of life as a frontier of therapeutic approach and prognosis. Pediatricians can play a key role in timely recognition and referral. They also emphasize the importance of complete orthopedic examination in order to exclude other associated deformities, and the apparent irrelevance of the underlying pathology for the success of early conservative treatment. A brief review of congenital dislocation of the knee is presented.
