About the study
The purpose of this study is to compare two different antibiotic regimens and techniques during total ankle arthroplasty (TAA).
Primary Objective: Comparable levels of vancomycin will be found in bone, soft tissue, and systemic samples between patient groups.
Secondary Objective: Compare 30 day and 90 day post-operative complication rates (infection) between the control (standard IV administration of vancomycin) vs the interventional group (intraosseous administration of vancomycin). The investigators hypothesize that there will be no difference in complication (infection) rates between groups.
