Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: It is a well performed study with an interesting, but not completely new information. Still it helps to increase the knowledge about the kinematic action taken into consideration for patient's treatment. The conclusion thus does not give us yet a precise plan in order to decide if the patients with medial ankle OA would benefit of axial alignment surgery or rather be treated by a total ankle replacement. Still the ankle fusion in severe axial deviation might be considered as the safest way to go.

Reviewer #2: This is a well-written and well-conducted study. In addition, the conclusion of it is absolutely correct.

The discussion expands quickly but well over the results and lead to a reasonable interpretation of the results. In addition, the limitations of the study are ok.
