What is an HTO?

HTO is a surgical procedure, in which an incision is made on the top part of the tibia to re-align the knee joint. Weight-bearing is transferred from the damaged part of the knee in order to decrease pain and halt the onset of arthritis in patients with knee osteoarthritis or one-sided malalignment.

Who is a good candidate for HTO?

Generally, HTO is indicated for young and active patients with unilateral knee osteoarthritis, often involving the medial compartment of the knee, and in cases of malalignment or misalignment of the knee, often with a “bow-legged” deformity. Candidates for HTO often need to have good stability in the knee, healthy cartilage in other parts of the knee, and not have advanced arthritis.

What are the advantages of High Tibial Osteotomy over knee replacement?

HTO can alleviate pain and enhance function by preserving the natural knee joint, which is great for younger, active patients who want to maintain a high level of activity. Other than knee replacement, HTO allows patients to continue high-impact activities and may delay the need for a knee replacement in the future.

What does rehabilitation look like after High Tibial Osteotomy?

Recovery after HTO takes several months. Patients can walk with the support of crutches or with a knee brace to limit their weight-bearing on the operated leg for a time. Physical therapy is necessary for retraining the muscles and restoring mobility. Most people are able to resume their normal activities in three to six months, but complete recovery may take up to a year.

How long will the results of HTO last, and will I need further surgery in the future?

Results of an HTO may last 10-15 years or longer depending on variables such as age activity level, and the progression of arthritis. Although the HTO is able to delay the need for a knee replacement, patients may require further surgery if the arthritis progresses in other parts of the knee.
