Clinical Orthopaedics and Related Research
|August 1, 1986
Summary
High tibial osteotomy effectively corrects varus gonarthrosis, with 92% excellent/good results. This surgical technique offers a successful alternative to total knee replacement for carefully selected patients.
Area of Science:
- Orthopedic Surgery
- Biomechanical Engineering
Background:
- Varus gonarthrosis is a debilitating knee condition.
- High tibial osteotomy (HTO) is a surgical option for correcting knee alignment.
Purpose of the Study:
- To evaluate the long-term outcomes of HTO for varus gonarthrosis.
- To assess deformity correction, functional results, and patient satisfaction.
Main Methods:
- Retrospective analysis of 31 consecutive HTO procedures.
- Evaluation of preoperative and postoperative tibiofemoral angles.
- Assessment using Coventry's criteria and the Hospital for Special Surgery (HSS) knee score.
Main Results:
- Successful correction of varus deformity to valgus alignment.
- 92% of patients achieved excellent or good outcomes.
- 88% reported subjective improvement, with reduced analgesic use post-surgery.
- Long-term results showed minimal deterioration over nine years.
Conclusions:
- HTO is a successful treatment for varus gonarthrosis in selected patients.
- Careful patient selection and precise surgical technique are crucial for optimal outcomes.
- HTO serves as a viable alternative to total knee replacement.
