[Closing-wedge valgus high tibial osteotomy].

Area of Science:

• Orthopaedic surgery
• Knee arthroplasty
• Osteotomy

Context:

• Varus arthritic knee treatment
• Lateral approach high tibial osteotomy
• Comparison with alternative treatments like medial distraction osteotomy, autologous chondrocyte transplantation, and alloplasty

Purpose:

• Evaluate outcomes of lateral approach high tibial osteotomy for varus arthritic knee
• Assess the role of this method in contemporary orthopaedic surgery
• Correlate surgical outcomes with pre-operative and post-operative parameters

Summary:

• 101 patients with moderate varus gonarthrosis underwent lateral valgus high tibial osteotomy and arthroscopy
• Outcomes assessed via clinical/radiographic evaluation and Lysholm score, with a 2-7 year follow-up
• Average Lysholm score improved by 22 points; average mechanical axis shifted from 2° varus to 6° valgus

Impact:

• Mid-term results demonstrate lasting success with a 90% satisfaction rate expected at 5 years
• Achieving good outcomes requires strict adherence to indication criteria, surgical technique, and arthroscopic treatment
• Mild overcorrection to 8 degrees of valgus is emphasized for optimal results, with comparable complication rates to distraction osteotomy.
