Brief Summary
The study evaluates the relation between the rotational alignment of the talar component (phi angle) and the antero-medial ankle pain in patients underwent total ankle replacement, at least one year after surgery. Moreover, the study aims to define a range of the phi angle associated with a lower frequency of antero-medial pain.

Outcome Measures
Primary Outcomes (2)
Phi angle
Relative angle (measured in degrees) between the alignment of the talar component of the implant, and the axis passing through the second metatarsal bone, in the dorsoplantar plane.
Through study completion, an average of 18 months
Antero-medial ankle pain
Sum of the antero and medial pain areas, measured as percentage with respect to the total body area in the considered plane.
Through study completion, an average of 18 months
Eligibility Criteria
Patients undergoing follow-up examination at a third-level hospital after total ankle replacement
You may qualify if:
- previous intervention of first implant of total ankle replacement, with at least 12 months of follow up and maximum 36 months
You may not qualify if:
- more than 36 months from the surgery of first implant of total ankle replacement
- previous revision surgery of ankle prosthesis
- previous intervention of ankle disarthrodesis and ankle prosthesis implant
