Uncommon unilateral congenital knee dislocation. A case report
Abstract
Introduction and importance The estimated incidence of congenital dislocation of the knee, also referred to as genu recurvatum, is approximately 1 in 100,000 live births. The purpose of this report is to present a rare case of unilateral congenital knee dislocation, highlighting the clinical presentation and management. Case presentation A 9-day-old female infant was born to a 30-year-old primigravida mother following an uncomplicated term pregnancy of 39 weeks and 4 days. Upon examination at the hospital, the infant presented with a hyperextended left knee. Additionally, there was a deep suprapatellar skin crease. A conservative treatment plan was initiated, involving serial long-leg casting and positioning of the foot to establish a plantigrade position. Discussion Congenital knee dislocation presents at birth with hyperextension and can limit knee movement. Diagnosis involves clinical examination and imaging to assess severity. Treatment varies by grade, with conservative methods like casting for mild cases and surgery for severe ones. Early intervention is critical for better outcomes. In this case, a Grade I congenital dislocation of the knee was successfully treated with reduction and casting. Conclusion In conclusion, this case report stands as a valuable addition to the medical literature, offering insights into a rare presentation of unilateral congenital knee dislocation and emphasizing the importance of early diagnosis and intervention in similar cases.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
