Computer-assisted double level osteotomy for severe genu varum.
High tibial osteotomy is commonly used for genu varum deformity in young and active patients. Corrective valgus osteotomy may however lead to an oblique joint line in case of associated femur varum or absence of tibia vara. The correction, needed to obtain long-term good clinical results, may increase the obliquity even more. To avoid this drawback, the authors have performed computer-assisted double osteotomy since 2001. They developed this new technique because combining distal valgus femoral osteotomy and proximal high tibial valgus osteotomy is a demanding technique. The purpose of this article is to present a technical procedure of computer-assisted double level osteotomy and to discuss its rationale and indications.
