Abstract
Background: The number of ankle arthroscopies being performed is increasing for both diagnosis and treatment of intra-articular pathology. Venous thromboembolism is an uncommon complication following ankle arthroscopy, but can have devastating outcomes. Publication of procedure-specific studies evaluating rates of post-operative thromboembolism is lacking, and current guidelines reflect this. Aim: To evaluate the incidence of thromboembolism in a consecutive series of patients undergoing diagnostic ankle arthroscopy, with intervention requiring immobilisation in a non-weight bearing cast post-operatively. Method: An analysis of consecutive patients undergoing diagnostic ankle arthroscopy with either ligament reconstruction or supra malleolar osteotomy by a single surgeon over a 12 month period. A retrospective review of the incidence of any complications was undertaken, with a particular focus on venous thromboembolism. Results: 104 patients underwent ankle arthroscopy during the 12 month period. All patients completed routine follow-up at 6 weeks, 3 months and 6 months. The overall complication rate was 3.8%. The incidence of venous thromboembolism in our series was 0.96%. Conclusion: Our incidence of venous thromboembolism with standard use of low molecular weight heparin in all patients is lower than previously published. Larger trials will aid in identifying whether chemoprophylaxis is required in all those undergoing ankle arthroscopy with post-operative immobilisation, or just patients with additional risk factors
