Clinical Trial Summary

The objective of this study is to compare primary total ankle replacement (TAR) performed with a customized procedure (prostheses customized for each patient based on his or her ankle morphology reconstructed from tomographic scans, and implanted via cutting guides customized for the patient) with standard primary TARs, considering: objective radiological results, subjective patient outcomes, and overall costs of both procedures

Intervention

Procedure:
• Total ankle arthroplasty
Patients who underwent ankle prosthesis implantation procedure with an anterior approach were involved in a longitudinal skin incision of about 12-15cm anterior to the tibio-tarsal joint in supine position. Once the deep layers were reached, passing through the anterior tibial tendon and extensor hallucis longus tendon sheath, the tibio-tarsal joint was then exposed. The operator proceeds to astragalic and tibial resections, once the appropriate size of implants was selected, the final components were implanted. In both groups, the basic prosthetic design approach will be 'three-component,' that is, with congruent mobile meniscus interposed between the tibial and astragalic components. At the end of the procedure, orthopedic walker boot was placed for 3 weeks, and progressive weight allowed.

Secondary	Visual Analogic Scale	Visual Analogue Scale (VAS) is a measurement instrument that measures a characteristic or attitude that is believed to range across a continuum of values and cannot easily be directly measured; operationally a VAS is usually a horizontal line, 100 mm in length, anchored by word descriptors at each end, where the patient marks on the line the point that they feel represents their perception of their current state. The VAS score is determined then by measuring in millimetres from the left hand end of the line to the point that the patient marks.	at baseline (day 0)
