HIGH TIBIAL OSTEOTOMY (HTO)
High Tibial Osteotomy (HTO) : This is a joint conserving surgery for young and active people with unicompartmental knee osteoarthritis (affecting only one compartment or half the joint) with varus deformity or bowed legs, who cannot comply with the restrictions of a knee replacement. Here, the bowed leg is straightened after making a cut in the shin bone (tibia) near the knee, and fixed by plate and screws. This surgery can give significant pain relief and allows unrestricted activity afterwards.
