Congenital dislocation of the knee. A report of 5 cases
Insights
Congenital knee dislocation and genu recurvatum in infants may result from abnormal fetal positioning in the womb. This theory is supported by cases, including one infant delivered via caesarean section.
Area of Science:
- Orthopedics
- Pediatric Medicine
- Developmental Biology
Background:
- Congenital dislocation of the knee (CDK) and genu recurvatum are rare pediatric orthopedic conditions.
- Etiology has been debated, with theories ranging from genetic factors to mechanical influences.
Observation:
- Presents findings on 3 infants with congenital dislocation of the knee.
- Includes 2 infants diagnosed with genu recurvatum deformity.
- Highlights a case involving an infant delivered via caesarean section.
Findings:
- Suggests abnormal intra-uterine fetal positioning as a significant causative factor for these knee deformities.
- Provides clinical evidence supporting the mechanical theory over previous concepts.
- The caesarean section case offers unique insight into potential in-utero developmental pressures.
Implications:
- Informs prenatal counseling and management strategies for high-risk pregnancies.
- May lead to new preventative interventions targeting fetal positioning.
- Contributes to a deeper understanding of congenital lower limb malformations.
Abstract:
Reports on 3 infants who suffered from congenital dislocation of the knee and 2 with genu recurvatum deformity are presented. The theory that abnormal intra-uterine fetal position may cause these deformities has gained support over previous concepts, as demonstrated by the baby born by caesarean section.

Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
Knee Joint
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...
