The study addresses the higher revision rates associated with total ankle replacements (TARs) and proposes a new patient-specific implantation (PSI) technique to improve outcomes.
Researchers used CT scans of 10 cadaver legs to determine the optimal positioning of the ankle prosthesis and assessed the accuracy of guiding block placements.
Findings indicate that the PSI technique has a reliable guiding block positioning, which is crucial for proper prosthesis placement, with an average deviation of 14.6° from the preoperative to postoperative joint axis.
