Workflow

Three steps to your result

From image upload to planning — straightforward and transparent.

Step 01

Upload your image

DICOM, JPG or PNG — simply drag and drop. Full-leg AP and lateral knee views are both supported.

Step 02

Analyse the limb axis

Set anatomical landmarks guided by the app. The lower limb axis is measured and all relevant angles are calculated automatically.

Step 03

Plan osteotomy

Plan HTO and DFO directly on the image. Simulate the correction and see the mechanical axis update in real time.

Step 04

Export your results

Download a PDF report or PNG with all measurements, angles, and the osteotomy plan included.
