Two-level Osteotomy for Genu Valgum with Tibia Valga: Surgical Planning and Execution

Area of Science:

• Orthopedic surgery
• Lower limb deformity correction
• Skeletal reconstruction

Background:

• Proximal tibial injury can cause tibia valga, leading to genu valgum, a common lower limb deformity.
• Management strategies for these deformities include growth modulation and corrective osteotomy.
• Osteotomy is typically performed in skeletally mature patients, with options for single, multiple, or gradual staged correction.

Observation:

• A novel single-stage, two-level osteotomy technique was applied to a 20-year-old patient.
• The procedure involved a medial closing wedge osteotomy of the distal femur and a translational osteotomy of the tibial shaft.

Findings:

• This two-level osteotomy method successfully addressed both genu valgum and tibia valga deformities simultaneously.
• Correction was achieved in a single surgical stage.
• The technique resulted in precise restoration of the lower limb's mechanical axis and the knee's joint line obliquity.

Implications:

• This approach offers a viable single-stage solution for complex lower limb deformities in skeletally mature individuals.
• It highlights the potential for improved surgical outcomes and efficiency in treating combined genu valgum and tibia valga.
• The method provides a reproducible technique for orthopedic surgeons managing these challenging conditions.
