Background: Tibial condylar valgus osteotomy (TCVO), or Chiba osteotomy, is a recognized procedure for treating advanced knee osteoarthritis in middle-aged individuals. Although its effectiveness is established, limited literature exists on its outcomes for specific conditions such as post-traumatic deformities, Blount disease (BD), and Pagoda-like proximal tibia varus deformities.
Hypothesis: We hypothesized that TCVO could improve both clinical and radiographic outcomes in patients with severe varus deformities, correcting lower-limb variances while preserving joint line obliquity (JLO) and patellar height in substantial varus deformities.

Chiba osteotomy is an effective technique for advanced knee osteoarthritis (KOA). The principle of the osteotomy is to correct both varus deformity and intra-articular joint congruity through an L-shaped osteotomy from the medial tibial condyle to the lateral intercondylar eminence. Previous studies have demonstrated that Chiba osteotomy is an effective method for alignment correction surgery for severe knee osteoarthritis.
