**Abstract**

Total knee arthroplasty in valgus knee deformities continues to be a challenge. It comprises only 10% of patients who undergo total knee arthroplasty. The surgeon should be aware of the technical aspects that differentiate it from the varus deformity: surgical exposure, bone cuts, ligament balancing, gap balancing, joint line obliquity, patellar tracking, preserving fibular nerve function, and selection of the implant. The aim of this chapter is to provide step-by-step comprehensive knowledge about different surgical techniques for the correction of severe valgus deformity in total knee arthroplasty.
