title: Bilateral congenital dislocation of the knee with ipsilateral developmental dysplasia of the hip--report of three patients.
abstract: Congenital dislocation of the knee (CDK) is a very rare condition. Here we report our strategy and results in treatment of three children with CDK. All three patients were treated with conservative method, and only one had underwent a surgical procedure on one knee. Of the remaining, we recorded a good outcome with conservative treatment in three knees, while two had poorer outcome as a result of musculoskeletal anomalies. We also present here a unique case of a child born without cruciate ligaments and patellas on both sides. We performed the operative procedure by Z-plasty of the extensor apparatus on one left knee according to Niebauer and King on one child. The clinical result of this procedure was very good. Five years after the operation we decided to perform an MRI examination to assess the postoperative status of the operated knee, especially the position and the shape of left patella. We found the asymmetry and high position of the operated patella resulting in patella alta. Compared to the initial clinical presentation, we consider all patients to have good clinical presentation nowdays.
