“…Various treatments for CKD have been described, including closed reduction, physiotherapy, serial casting, minimally invasive or open quadricepsplasty and femoral shortening 6,[24][25][26][27][28][29][30][31][32] . The success rate of manipulation is 77%, and the outcome improves further after treatment with serial casting 25 .…”

ObjectivesCongenital Knee Dislocation (CKD) or Genu Recurvatum is a rare condition affecting 1 over 100,000 newborns, characterized by anterior hyperextension of the knee joint, increased transverse skin folds over the anterior surface of the knee and prominence of femoral condyles into the popliteal fossa. Prenatal diagnosis is poorly described in the literature and challenging, especially when it appears isolated and not in the context of polymalformative or syndromic patterns. The purpose of this study is to provide a comprehensive review of the available literature on prenatal diagnosis and postnatal outcome of this rare condition, to summarize the current evidence on this topic.MethodsWe performed a systematic review of the literature searching for prenatal diagnosis of CKD in all major internet‐based medical databases. A predefined combination of specific key words was used, focusing on intrauterine manifestations, diagnostic methods, prenatal behavior, postnatal treatment and neonatal outcome as well as long‐term outcome on ambulation, motion and joint stability. Study quality was assessed by means of National Institute of Health tool for the quality assessment of Case Series Studies. A summary of results was carried out providing proportions and rates of diagnostic and prognostic features associated with this rare condition.ResultsTwenty cases were retrieved for analysis including nineteen collected from the systematic review and one unpublished case from our experience. Median gestational age at prenatal diagnosis was 22 weeks (range 14‐38 weeks), generally by US. Bilaterality was observed in 11/20 (55%), the condition was isolated in 7/20 cases (35%) and associated to other anomalies in 13/20 cases (65%). An association was observed with oligohydramnios (20%) and invasive procedures were performed in 11 cases (55 %). Genetic studies were normal in all isolated cases and few genetic syndromes were present in 10 of the 13 (77%) non‐isolated cases for which information was available (Larsen, Noonan, Grebe, Desbuquois and Escobar syndromes). There were 7 terminations of pregnancy, of which 6 with associated anomalies and one isolated, 11 livebirths, one intrauterine death and one neonatal death. All fetal or neonatal demises were in fetuses with associated anomalies or abnormal genetics. Postnatal treatment was essentially conservative with only two reports (18% of the 11 liveborn neonates) of surgical interventions, all in cases with associated anomalies. The postnatal follow up was in most of the cases up to the first year and the motor outlook appears normal.ConclusionsCKD is a rare fetal anomaly with a prenatal diagnosis achievable from the early second trimester for which favorable outcome can be predicted when no associated anomalies are present. Prenatal diagnosis should include detailed US assessment and amniocentesis for extensive genetic studies, particularly in non‐isolated cases. Postnatal early treatment achieves success in most cases without surgical intervention and leads to normal motor outlook.This article is protected by copyright. All rights reserved.

“…The diagnosis is generally made at birth, given the position of the knee, which is confirmed radiologically [11]. For this reason, it is also important that the delivery personnel perform a complete physical examination to rule out other syndromes or associated anomalies [10].…”

Bilateral Congenital Knee Dislocation in Colombia: Case Report and Literature Review

et al. 2022

View full text Add to dashboard Cite

Congenital knee dislocation (CKD) is a rare disease with an estimated incidence of 1 per 100,000 live births, characterized by a rare musculoskeletal malformation in genu recurvatum deformity present at birth, affecting one or both lower limbs. The diagnosis may be suspected during ultrasound when observing that the situation of the extremities is not correct, and is confirmed by physical examination at birth, with plain radiography being helpful to establish the degree of severity. At present there are controversies regarding treatment and there is no definitive protocol. We present a new case of CKD, observed in the city of Manizales, diagnosed immediately after birth.
