HTO

Full Definition

High tibial osteotomy (HTO) is a surgical technique used to treat knee osteoarthritis, particularly in younger patients with unicompartmental disease. The procedure involves making a precise cut in the upper portion of the tibia and adjusting the alignment to redistribute weight-bearing forces away from the damaged compartment. This joint-preserving surgery can delay or eliminate the need for total knee replacement in appropriately selected patients.

Usage

Usage note: Often confused with other osteotomy abbreviations; specify 'high tibial' when first mentioned.
