In this case, α60 was 14° (a) and β was 7.5° (b) varus stress JLCA was 6° and (c) valgus stress JLCA was − 1°). The value of β was smaller than α60; thus, TCVO and OWHTO were performed to achieve the optimal alignment (d). JLCA: joint convergence angle. TCVO: tibial condylar valgus osteotomy. OWHTO: open wedge high tibial osteotomy. α60: The correction angle calculated as the postoperative WBL passed through the point of 60%. β: The value obtained by multiplying the sum of both JLCAs by 1.5
