Congenital dislocation of the knee

Area of Science:

• Orthopedics
• Pediatric Orthopedics
• Developmental Biology

Background:

• Congenital knee dislocation is characterized by fixed hyperextension and anterior tibial displacement.
• This condition often co-occurs with congenital hip dysplasia, affecting nearly half of affected patients.
• Idiopathic congenital knee dislocation requires timely management to prevent long-term joint dysfunction.

Purpose of the Study:

• To review treatment outcomes for congenital knee dislocation in pediatric patients without other neuromuscular syndromes.
• To evaluate the efficacy of early closed reduction and the necessity of open reduction.
• To assess the simultaneous treatment of congenital knee dislocation and hip dysplasia using the Pavlik harness.

Main Methods:

• Retrospective review of seventeen patients with 27 affected knees diagnosed with congenital knee dislocation.
• Analysis of treatment strategies including closed reduction, open reduction, and Pavlik harness application.
• Assessment of treatment success based on successful reduction and achieved knee joint motion.

Main Results:

• Early closed treatment resulted in successful knee reduction and satisfactory motion in most cases.
• Open reduction was necessary for patients who did not respond to closed reduction techniques.
• The Pavlik harness demonstrated efficacy in simultaneously treating both congenital knee dislocation and associated hip dysplasia.

Conclusions:

• Early closed reduction is the preferred initial treatment for congenital knee dislocation.
• The Pavlik harness offers a viable, simultaneous treatment option for concurrent knee and hip dysplasia.
• Prompt management is crucial for achieving favorable outcomes in congenital knee dislocation.
