Abstract

Purpose

The purpose of this study was to evaluate changes of patellar height and posterior tibial slope angle following uniplanar medial opening wedge high tibial osteotomy using a novel wedge-shaped spacer implanation concurrent with proximal partial fibulectomy.

Methods

All patients who underwent uniplanar medial opening wedge high tibial osteotomy using a novel wedge-shaped spacer implanation concurrent with proximal partial fibulectomy between January 2017 and February 2019 were included and assessed retrospectively. Radiological assessment was made in terms of the changes in patellar height and posterior tibial slope angle between pre-operative and post-operative radiographs.

Results

Thirty-five patients (9 males and 26 females) with a mean age of 57.3 years (range 50.8–64.2 years) were enrolled in this study protocol and demonstrated decreased posterior tibial slope angle post-operatively (9.7° ± 2.5° pre-operatively and 7.3° ± 1.8° post-operatively, P < 0.001). Patellar height was unchanged significantly post-operatively (Caton–Deschamps: 0.83 ± 0.12 pre-operatively and 0.82 ± 0.09 post-operatively, P > 0.05).

Conclusions

Uniplanar medial opening wedge high tibial osteotomy using a novel wedge-shaped spacer implanation concurrent with proximal partial fibulectomy can decrease posterior tibial slope and maintain the patellar height.
