Summary

High tibial osteotomy (HTO) shows a 54.1% survival rate after 18 years for knee osteoarthritis. This long-term survival indicates HTO is a viable option to delay total knee replacement (TKR).

Area of Science:

  • Orthopedic Surgery
  • Biomechanical Engineering

Background:

  • High tibial osteotomy (HTO) frequency has declined due to surgical complexity and increased total knee replacement (TKR) prevalence.
  • Limited data exists on HTO survival rates beyond 10 years.

Purpose of the Study:

  • To evaluate the long-term survival rates of HTO.
  • To assess the influence of patient age, gender, and mechanical axis on HTO outcomes.
  • To present results with over 18 years of follow-up.

Main Methods:

  • Retrospective analysis of 134 lateral closing-wedge HTOs in 111 patients.
  • Investigation of survival rates, age, gender, and mechanical axis influence.
  • Long-term follow-up exceeding 18 years.

Main Results:

Treatment of Ankle Osteoarthritis with Total Ankle Replacement Through a Lateral Transfibular Approach

Published on: January 24, 2018

  • Survival rates: 94% at 5 years, 79.9% at 10 years, 65.5% at 15 years, and 54.1% at 18 years.
  • Patient age significantly impacted survival.
  • Gender and mechanical axis showed no significant influence on survival.

Conclusions:

  • HTO demonstrates a 54.1% survival rate at 18 years.
  • HTO serves as a valuable procedure to postpone the need for total knee replacement.
  • Long-term HTO outcomes support its role in managing knee osteoarthritis.
