How to deal with a 22° ANTERIOR tibial slope deformity?
The problem with extra medullary guide is that you need to be parallel to tibial axis , because deformity the guide is no longer parallel so if you do it as usual the cut is wrong.

1-Line tibial axis
2-Line anterior cortex proximal and distal
3-Line a parallel line to 1
Distance proximal and distal from 2&3 is what u need to adjust guide to be really parallel(Here1.5cm prox 2cm distal) @OrthoFolks @JArthroplasty @EdinburghKnee @jointdocShields @NaanDerthaal
