Summary
Proximal tibial anterolateral opening-wedge osteotomies effectively correct lower-extremity malalignment. This biplanar approach addresses genu recurvatum and genu valgus in a single procedure, improving patient outcomes.
Area of Science:
- Orthopedic surgery
- Biomechanics
- Lower extremity reconstruction
Background:
- Proximal tibial anterolateral opening-wedge osteotomies are utilized for lower-extremity realignment.
- Common indications include genu recurvatum with genu valgus alignment, often associated with a flat tibial slope.
Purpose of the Study:
- To evaluate the efficacy of the proximal tibial anterolateral opening-wedge osteotomy for correcting combined genu recurvatum and genu valgus malalignment.
Main Methods:
- A biplanar surgical approach was employed to address multiple components of lower-extremity malalignment.
- Intraoperative imaging and spacers were used to verify correction accuracy.
- Heel height was measured to assess correction of the sagittal plane deformity.
Main Results:
- The anterolateral tibial osteotomy procedure successfully corrected concomitant genu recurvatum and genu valgus.
- The biplanar technique allowed for simultaneous correction of both deformities in a single operation.
- Plate fixation and bone allograft were used to secure the osteotomy site.
Conclusions:
- The proximal tibial anterolateral opening-wedge osteotomy is an effective surgical technique for correcting combined genu recurvatum and genu valgus.
- This biplanar approach offers a single-stage solution for complex lower-extremity malalignments.
