About the trial
What the trial wants to find out
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
The 2 groups in the trial
- TraditionalExisting treatment, for comparison
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)
Treatment: Total ankle arthroplasty
- CustomTreatment being tested
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.
Treatment: Total ankle arthroplasty
