Outcome of Management of Congenital Dislocation of the Patella at Soba University Hospital, Khartoum

Background: Congenital dislocation of the patella (CPD) is a rare anomaly which produces a marked contracture of the quadriceps mechanism and deformity of the knee. Conservative treatment is unlikely to succeed.Objective: To study the outcome of management of (CPD) at the Department of Paediatric Orthopaedics Soba University Hospital.Materials and Methods: A retrospective review of the records of six patients (five females, one male) with a mean age of 9.5 years (range 5 to 15). Three cases were bilateral. All underwent operative reconstruction. The assessment of the outcome as excellent, good, fair or poor was based on the Ferris classification which included, range of movement, stability and absence of pain.Results: The outcome was good in all cases, and there were no significant complications.Conclusion: These results are similar to reports elsewhere and we advise reconstruction of the deformity as soon as reasonably possible after diagnosis.Key word: Congenital dislocation of the patella, Ferris classification, Soba, Sudan
