Osteotomy means cutting of the bone. High tibial osteotomy (HTO) is a surgical procedure aimed at correcting knee deformities caused by conditions like osteoarthritis or misalignment. In a knee osteotomy, the surgeon cuts and reshapes either the tibia (shinbone) or femur (thighbone). This procedure is particularly effective in redistributing weight from a damaged area of the knee joint to a healthier cartilage, alleviating pain and improving joint function.
A high tibial osteotomy is often recommended for various reasons, this includes correcting development bone misalignments that could cause issues in the future if left untreated. It helps to realign the bone with the joint and restore normal alignment. High tibial osteotomy is also used to treat cartilage damage, such as a single hole in the cartilage, or more widespread degenerative changes like osteoarthritis in a specific part of the knee. For individuals with knee instability or wobbliness, an osteotomy can be performed alongside other procedures, such as ligament reconstruction, to improve stability. Misalignments like knock knees or bowlegs, which can result from injury or disease, often cause abnormal weight distribution across the knee joint, leading to additional wear and tear. This malalignment increases stress on the joint, which worsens pain and can lead to further degeneration, making an osteotomy an important option to restore balance and alleviate symptoms.
High tibial osteotomy surgery involves making precise cuts in the tibia (shinbone) and realigning it to shift the load-bearing axis of the knee. By doing so, it reduces stress on the damaged portion of the knee and delays the progression of arthritis.
