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 states that navigation aids (NAV) could enhance HTO and that CAOS may simplify the procedure over time as the technology improves, though surgical experience remains important and CAOS is currently best used in specialized centers given its complexity.
