Core Tip

Core Tip: Patients undergoing total hip arthroplasty are a high-risk cohort for venous thromboembolism postoperatively. Thromboelastography (TEG) is a modality for investigating global coagulation status. There is limited evidence surrounding the use of TEG in this patient group. Our observational study revealed this patient cohort exhibits a progressively hypercoagulable state postoperatively, characterized primarily by elevated TEG maximum amplitude. The clinical significance of this hypercoagulability is yet to be fully elucidated, however suggests further outcome-based studies exploring anti-coagulation therapy in this cohort may be beneficial.
