Summary
This summary is machine-generated.

High tibial osteotomy (HTO) shows good outcomes in 51% of patients, with 36% failing over time. Long-term success depends on achieving 10+ degrees of valgus correction.

Area of Science:

  • Orthopedic Surgery
  • Biomechanics
  • Sports Medicine

Background:

  • High tibial osteotomy (HTO) is a surgical procedure to correct knee alignment.
  • Understanding long-term outcomes is crucial for patient selection and surgical planning.

Purpose of the Study:

  • To evaluate the long-term results of high tibial osteotomy.
  • To identify factors influencing the success of HTO.

Main Methods:

  • Retrospective review of 75 patients (88 knees) undergoing HTO over 12 years.
  • Minimum 5-year follow-up or until failure.
  • Subjective and roentgenographic assessments using defined outcome criteria.

Main Results:

  • 51% good, 9% fair, 4% poor, 36% failed outcomes.

  • Satisfactory results at 2 years (94%), 5 years (87%), and 10 years (69%).
  • Correction of 10+ degrees of valgus correlated with better long-term results.

    • Conclusions:

    • HTO can provide satisfactory long-term outcomes, but a significant failure rate exists.
    • Achieving adequate valgus correction is key for better results.
    • Patient age and gender did not impact outcomes, though women took longer to become support-free.
