Area of Science:

  • Orthopedic Surgery
  • Biomechanical Engineering

Background:

  • Unicompartmental knee joint arthritis often necessitates surgical intervention.
  • Proximal tibial osteotomy (PTO) has been utilized as a surgical treatment since 1970.

Purpose of the Study:

  • To evaluate the long-term efficacy of proximal tibial osteotomy (PTO) for treating unicompartmental knee arthritis.
  • To determine the functional outcomes and symptom relief provided by PTO over an extended follow-up period.

Main Methods:

  • A retrospective review of 279 proximal tibial osteotomies (PTO) in 230 patients performed between 1970 and 1995.
  • Utilized revision to total knee replacement or death as primary endpoints, supplemented by clinical evaluations, radiographs, and patient questionnaires.

Main Results:

  • At an average 13-year follow-up, 116 patients (42%) reported no symptoms, indicating a good outcome.
  • The study included 279 osteotomies in 230 patients, with 83 deaths and 19 lost to follow-up.
  • Proper surgical alignment is crucial for successful long-term outcomes.

Conclusions:

  • Proximal tibial osteotomy (PTO) can achieve good function and symptomatic relief for patients with unicompartmental knee arthritis.
  • Adherence to surgical principles, particularly maintaining proper alignment, is key to achieving average relief of 10 to 14 years.
