Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Traditional

In the STANDARD group, patients will undergo a primary TAR by implanting a prosthetic model of a standard design, that is the same for all using the usual surgical technique and instrumentation (based on the use of external leg guidance)

Group Type ACTIVE_COMPARATOR

Total ankle arthroplasty

Intervention Type PROCEDURE

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.

Custom

In the PERSONALIZED group, patients will undergo a primary TAR by implanting a prosthetic model with a design specifically based on each patient's actual ankle morphology and using PSI surgical technique and instrumentation.
