Brothers with genu recurvatum

Area of Science:

• Orthopedics
• Genetics
• Pediatric Growth Plate Disorders

Background:

• Genu recurvatum is a rare knee deformity, often linked to proximal tibial growth plate injury.
• Idiopathic cases, without a clear cause, represent a smaller but significant subset.

Observation:

• The study details two brothers presenting with identical, unilateral genu recurvatum.
• Deformity onset occurred at 17 years old in both, progressing rapidly over a short period.
• No history of trauma, other orthopedic conditions, or known genetic disorders was reported.

Findings:

• The simultaneous onset and similar progression in affected siblings, despite differing severity, point towards a shared etiology.
• The absence of external factors strongly implicates intrinsic, likely heritable, risk factors in the development of this specific genu recurvatum presentation.

Implications:

• This case series highlights the potential role of genetic predisposition in idiopathic genu recurvatum.
• Further research into familial patterns and genetic markers is warranted for understanding and managing this rare deformity.
• Identifying heritable factors could lead to improved diagnostic approaches and targeted interventions for affected individuals.
