Comparison of Customized and Standard Total Ankle Prostheses

Comparison of Customized and Standard Total Ankle Prostheses: a Pilot Study

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
