Computed Tomography of Osteolysis Related to Total Ankle Replacement

CT-Based Descriptive Classification for Residual Talar Defects Associated With Failed Total Ankle Replacement: Technique Tip

“…The longevity of a total ankle replacement (TAR) is dependent on several variables, including patient selection, implant selection, surgeon experience, patient comorbidities, and proper technical insertion. [1][2][3][4][5][6][7][8][9][10][12][13][14][15] One issue threatening the survivorship of total ankle replacements is periprosthetic osteolysis. 3,5,7,8 The process of periprosthetic osteolysis can begin with cyst formation in the bone beneath the implant.…”

“…1-10,12 -15 One issue threatening the survivorship of total ankle replacements is periprosthetic osteolysis. 3,5,7,8 The process of periprosthetic osteolysis can begin with cyst formation in the bone beneath the implant. This may progress to a point where large bony defects leave the component unsupported and subject to aseptic loosening, implant subsidence, and potentially catastrophic failure (Figure 1).…”
