Incidence of Subtalar Joint Fusion After Isolated Ankle Fusion

It is important to know a truer incidence of the need for subtalar and midfoot fusions, following an isolated ankle fusion, in order to better inform our patients of the likelihood of needing further surgery in the future. It is also important to understand whether pre-existing radiological arthrosis is likely to lead to the need for a fusion in the future and also how important the alignment of the ankle joint, after a fusion, may influence that. The aim of the study is to review the patients' notes and radiology who have had a previous isolated ankle fusion and then to see whether they subsequently required further surgery.

Intraosseous vs. Intravenous Vancomycin Administration in Total Ankle Arthroplasty

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.

Canadian Orthopaedic Foot and Ankle Society Surgical Treatment of Ankle Arthritis Outcome Study

The purpose of this study is to see if the clinical outcome success rate of Total Ankle Arthroplasty is similar to that of Ankle Arthrodesis over a period of 10 years. This will include looking at whether Total ankle arthroplasty results in a lower rate of hindfoot arthrosis and arthritis after surgery compared to ankle joint arthrodesis and if the rate of complications and revision surgery is acceptable when compared to Ankle Arthrodesis over a period of 10 years.

Total Ankle Replacement: Clinical and Radiological Outcomes

This retrospective and prospective study intends to evaluate the epidemiology and effectiveness of ankle joint surgery in patients operated from January 2011 to March 2026, evaluating the results both clinically and radiographically.
