Researchers found the anteriorly translated talus in patients with osteoarthritis was relocated to an anatomical position at 6-month follow-up after three-component total ankle arthroplasty, according to results of this study.
“In most cases, an anteriorly translated talus in osteoarthritic ankles was restored to an anatomic position within 6 months after successful total ankle arthroplasty,” the researchers wrote in the study. “Adequate soft tissue balancing, optimal sagittal alignment and anatomical positioning of the talar component may help restoration of the talus into the mortise.”
The researchers divided 104 patients into two groups consisting of ankles with an anteriorly translated talus or a non-translated talus, according to the abstract. All patients underwent three-component total ankle arthroplasty (TAA) and the mean follow-up was 42.8 months.
At 6 months, the researchers noted 92% of ankles that had anterior translation of the talus were relocated. At 12 months, 96% of ankles were relocated. There was no significant difference between American Orthopaedic Foot and Ankle Society scores, range of motion and radiographic outcomes between the two groups at final follow-up. However, two ankles with anterior translation of the talus were not relocated until final follow-up, according to the abstract.
