Abstract

Introduction

Compared to the standard Tomofix plate, the anatomical Tomofix medial high tibial (MHT) plate has been shown to improve anatomical fit and post correction tibial contour, following high tibial osteotomy (HTO). Clinical data on surgical complications, osteotomy union rates and survivorship with the anatomical Tomofix MHT plate however remain limited. This study reports mid-term results of HTO surgery, using the anatomical Tomofix MHT plate.

Methods

All patients undergoing HTO surgery using the anatomical Tomofix MHT plate between 2017 and 2022 were included in the study. Data on complications, osteotomy union rates and survivorship were collected prospectively and retrospectively analysed.

Results

78 HTO procedures were performed using the anatomical Tomofix plate in 68 patients. Follow-up ranged between 6 weeks and 5 years. Postoperative complications included 5 hinge fractures that united without further intervention, 1 deep vein thrombus and 1 subclinical pulmonary embolism. There were no wound problems and no returns to theatre, other than for planned removal of metalwork at 1 year. All osteotomies united with no loss of correction. Only 1 HTO was successfully revised to a partial medial knee replacement 2.5 years following osteotomy. The 5-year survivorship was 98.7%.

Conclusion

The anatomical Tomofix MHT plate achieves excellent biomechanical stability and union rates in HTO surgery, with minimal complications and excellent mid-term HTO survivorship.
