Summary
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.
