Study Overview
Brief Summary
The study is a reliability (reproducibility) study on a single measurement procedure. Reliability (reproducibility) will be assessed by repeating the whole measurement procedure twice. The measurement procedure studied is the generation of a long ankle view image based on a radiographic assessment followed by a manual assessment of the medial-distal tibial angle.
Detailed Description
The study is a reliability (reproducibility) study on a single measurement procedure. Reliability (reproducibility) will be assessed by repeating the whole measurement procedure twice. The measurement procedure studied is the generation of a long ankle view image based on a radiographic assessment followed by a manual assessment of the medial-distal tibial angle (MDTA).
In order to assess the value of different assessment methods of the MDTA, several variants will be considered, which are all applied to the same long ankle view image. To determine the intra- and interrater reliability of the manual assessment, this assessment will be done twice by different observers (one doctoral student, one radiologist) and repeated within each observer.

Outcomes
Primary Outcomes
medial-distal tibial angle
Time Frame: Day 1 (There is only one single day of contact for each patient)
