Single Level Closed Wedge Osteotomy for Bilateral Genu Valgus with Isolated Tibial Angulation Deformity: A Case...

Area of Science:

• Orthopedic Surgery
• Pediatric Orthopedics
• Biomechanical Engineering

Background:

• Genu valgus, characterized by outward knee angulation, can cause abnormal loading and patellar maltracking.
• Pathological genu valgus (femorotibial alignment >12° after age 8) often requires correction.
• Idiopathic bilateral genu valgum with tibia valga is uncommon, particularly without femoral involvement.

Observation:

• A 17-year-old male presented with a 6-year history of progressive bilateral knee deformity, difficulty walking/running, and pain.
• Investigations revealed isolated bilateral tibial valgus deformity, with no femoral contribution.
• The patient underwent serial Single-level Proximal Medial Closed Wedge Osteotomy on both knees over 3 months.

Findings:

• The surgical intervention successfully corrected the bilateral tibial valgus deformity.
• The patient reported good functional outcomes post-osteotomy.
• Single-level proximal medial tibial osteotomy is effective for rare cases of idiopathic genu valgum with tibia valga.

Implications:

• This approach offers a safe and effective strategy for managing specific types of genu valgus deformities.
• Highlights that genu valgum is not exclusively caused by distal femoral deformities.
• Emphasizes the importance of accurate diagnosis to guide appropriate surgical correction.
