This document discusses techniques for high tibial osteotomy (HTO) and the potential role of computer-assisted orthopedic surgery (CAOS) in improving HTO. It notes various HTO techniques including closing-wedge, opening-wedge, and dome osteotomies. It suggests that navigation aids (NAV) could enhance HTO. It acknowledges that CAOS may simplify and improve HTO but cautions that the technique is demanding and should only be used in specialized centers with experienced surgeons, as high-tech tools cannot replace surgical skill and experience.
