“…Consequently, it is important to consider that the patient's condition could also be explained by an isolated congenital dislocation of the knee, or by an AMC-associated dislocation. (16)(17)(18) Likewise, the patient presented with some clinical features compatible with the alternative diagnosis of congenital knee dislocation, such as joint instability, reduction of dislocation with snap or piston, muscle retraction (knee quadriceps, hip adductors), restricted range of motion (hip abduction) and presence of skin folds or grooves, (18) which were more noticeable after achieving complete improvement ( Figure 3).…”

Congenital hyperextension deformity of the knees due to arthrogryposis multiplex congenita? Case report

et al. 2020

Introduction: Arthrogryposis multiplex congenita is a disorder characterized by non-progressive joint contractures. It has an estimated prevalence of 1 in every 3 000-5 000 live births, with the same male-to-female ratio.Case presentation: This is the case of a male newborn with adequate prenatal care checkup appointments, who presented with a congenital deformity of the lower limbs. On physical examination, he had hyperextension of the knees (passive flexion of 20° in the left leg and 30° in the right leg), and painful active movement. On admission, peripheral pulses had good intensity, and adequate distal perfusion was found. Barlow and Ortolani maneuvers were negative, and no midline lesions were observed in the spine. The patient was diagnosed with arthrogryposis multiplex congenita and received multidisciplinary treatment to avoid early morbidity and mortality.Conclusion: To attain satisfactory clinical development in patients with arthrogryposis, it is essential to have a high level of antenatal suspicion, as well as appropriate prenatal checkups. All this allows for proper management, minimizing diagnostic errors, avoiding unnecessary procedures, and performing effective and timely treatment with outstanding results.

“…As the passive flexion was not possible at all at the initial visit, that is, <30°, so it fell in group 3 of Abdelaziz and Samir [1] grading of CDK and so V-Y quadricepsplasty was recommended. In the presented case, the patient had deep anterior skin grooves and fell in type II of Mehrafshan et al [10] reduction and stability criteria. However, the parents did not consent for the operative intervention.…”

Congenital knee dislocation (CKD) is a deformity in which unnatural hyperextension is possible at the knee much beyond the normal 0° full extension while the flexion is severely restricted. Incidence of this rare congenital malformation is 1/100,000 live births. We present a clinical case of unilateral CKD in a 2-week-old female child and our approach of treatment using serial casting. We have been able to demonstrate that if initiated early, within first few weeks of life, the congenital deformity of knee can be managed conservatively without any surgical intervention even in higher grades.

“…The deformity can be unilateral or bilateral, with an estimated incidence of 1 in 100 000 deliveries and has a female predominance. 1 The etiology of congenital dislocation of the knee might involve extrinsic factors, including fetal molding due to oligohydramnios or breech position, abnormalities of the anterior cruciate ligament, and quadriceps contracture, or, rarely, intrinsic factors, such as Larsen syndrome, arthrogryposis, Ehlers-Danlos syndrome, and achondroplasia. 2 Successful management depends on the severity of the congenital knee dislocation and includes physiotherapy, serial casting, and/or surgery.…”

A female infant was delivered at 39 weeks of gestation via cesarean delivery because of nonreassuring fetal status. Prenatal sonography performed 1 week before delivery revealed oligohydramnios. Postdelivery, both knees were hyperextended, with no other anomalies (Figure 1). Radiography of both knees showed posterior dislocation of the femur on the tibia (Figure 2); thus, bilateral congenital dislocation of the knee was diagnosed.
