Congenital dislocation of the knee in combination with Meyer-Gorlin syndrome: A case report

BACKGROUND: Meyer-Gorlin syndrome is a rare genetic and autosomal recessive disease that is characterized by the classical triad, including, microtia, very small size or complete patellar absence, and nanism. CLINICAL CASE: Herein, presented the first clinical case description of a Russian patient with Meyer-Gorlin syndrome in combination with congenital anterior shin dislocation. The main clinical disease manifestations are characterized by a combination of microtia, patellar pathology, and dwarfism. DISCUSSION: In the practice of pediatric orthopedic surgeons, cases of congenital knee dislocations are extremely rare, especially as part of any syndromes, which cause interest in the presented clinical case publication. Our patient analysis, as well as the patients described in the literature, showed the presence of typical clinical manifestations, which allowed us to suspect the presence of Meyer-Gorlin syndrome during a clinical examination. CONCLUSIONS: This report is the first case of combined congenital knee dislocation and Meyer-Gorlin syndrome with a diagnostic triad (short stature, microtia, and patellar aplasia) in the Russian Federation. Conservative treatment with constant traction and flexion must be carefully performed to avoid complications. Without the effect of conservative therapy, surgical treatment is indicated.

MANAGEMENT OF A DELAYED PRESENTATION OF CONGENITAL KNEE DISLOCATION IN A 14 MONTH OLD CHILD WITH LARSENS SYNDROME AND PIERRE ROBIN SEQUENCE

Larsens syndrome is a rare genetic disorder characterized by multiple joint dislocations, abnormal facial features, and ligamentous laxity.Dislocation can involve Hips, knees, elbows, and other joints. it was first described by Larsen et al in 1950 [1]. Pierre Robin sequence is another rare congenital birth defect That is characterized by microganthia, glossoptosis and cleft palate which can lead to variety of functional abnormalities including feeding , breathing and hearing [2,3]. Here is a case report of a14-month-old child with Larsens syndrome who presented late with multiple joints dislocation including (elbow, hips, knees, and ankle), and failed management of knee dislocation.

Successful Early Non-Operative Management of Congenital Knee Dislocation: Demonstration via a Case Report

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.

Neglected intrauterine bilateral congenital knee dislocation

Bilateral congenital knee dislocation is a rare deformity which may present with other musculoskeletal abnormalities. In the early period, conservative treatment options have a high chance of success. However, in later stages, surgical treatment is indicated in neglected or unresponsive cases to manipulation in the early period. Herein, we present a rare case of bilateral congenital knee dislocation which was diagnosed after birth. Retrospective examination revealed that it occurred in the antenatal period and neglected.

Congenital dislocation of the knee: a morphological study

Background. Congenital knee dislocation is a rare disease of the musculoskeletal system (1 in 100,000 live births). In the literature, few studies have described the anatomical changes characteristic of this pathology, which are only revealed during surgical treatment. Aim. This study aimed to evaluate the pathomorphological features of the ligamentousarticular apparatus and thigh muscles with congenital knee dislocation on autopsy material. Materials and methods. The study included two fetuses with bilateral congenital knee dislocation after spontaneous miscarriage at 18 and 20 weeks of gestation and one stillborn fetus with bilateral congenital knee dislocation at 29 weeks of gestation. The comparison group was composed of two fetuses after spontaneous miscarriages at 18 and 20 weeks of gestation and one stillborn fetus at 25 weeks of gestation without anomalies of the lower extremities. Results. Various abnormalities and displacements of the anatomical structures, as well as degenerative dystrophic changes in the soft tissues during histological examination, were found. Pathomorphological changes in the control group were not detected. Conclusion. Pathomorphological changes are the main manifestations of congenital knee dislocation in the studied fetuses.

Congenital knee dislocation: a rare and unexpected finding

Congenital knee dislocation is a rare condition of unknown aetiology. It could be associated with syndromes or may occur as an isolated entity. The severity of the deformity determines the method of treatment. Treatment options range from conservative casting to surgical correction. The case presented is of a newborn with an isolated grade II dislocation treated with serial casting. On follow-up at 2 years, the patient had a good outcome, with full range of motion and independent mobility.
