Takedown of Painful Ankle Arthrodesis to Total Ankle Arthroplasty: A Case Series of 77 Patients
Pain after an ankle arthrodesis procedure can be common especially if misaligned or if adjacent joint arthritis begins to develop. Treatment options are limited and pantalar fusions can lead to gait disturbances due to changes in biomechanics leading to further problems. A takedown of the arthrodesis and conversion to a total ankle arthroplasty has been proposed in the past with limited literature to support this approach. This new study by Schuberth et al provides the largest cohort and longest follow up to date for this approach. In this study they included 77 patients with a mean follow up of 8.3 years and a mean age of 58.9 and evaluated for retention of the implant, complications and outcomes. They found that 88% of patients successfully retained the implant and the AOFAS, Buechel-Pappas and VAS scores all improved from preoperative values with less satisfaction in patient who required a revision surgery from implant failure. This study determined that the conversion to a total ankle arthroplasty is a viable option in the case of a painful ankle arthrodesis.
