Frequency of Vascular Events With Short-term Thromboprophylaxis in Fast-track Hip and Knee-arthroplasty.
An observational study of Thromboembolic Events and Post-operative Bleeding, run by Copenhagen University Hospital, Rigshospitalet at 6 sites in Denmark.
Trial summary
There are many different views regarding ideal duration and type of thromboprophylaxis after hip or knee surgery. An important factor in Fast-track surgery is early mobilization, which in itself is thought to prevent clotting. Read more about this study

About this study
Official title: Frequency of Vascular Events With Short-term Thromboprophylaxis in Fast-track Hip and Knee-arthroplasty
There are many different views regarding ideal duration and type of thromboprophylaxis after hip or knee surgery.
An important factor in Fast-track surgery is early mobilization, which in itself is thought to prevent clotting.
The investigators hypothesize that there is no increase with regards to thrombosis in patients receiving fast-track surgery with early mobilization and chemical thrombosis prophylaxis only during hospitalization.
Read the detailed description
Major orthopaedic surgery is related to development of thrombosis. It is well known that pharmacological prophylaxis reduces the risk of thrombosis after surgery but there are still doubt about the best type of prophylaxis and duration of treatment. The American College of Chest Physicians recommend thromboprophylaxis with either Low molecular weight heparin, factor Xa-inhibitors or Vitamin-K-antagonists for up til 10 days after total knee replacement (TKR) and 35 days after total hip replacement(THR). However whether these recommendations are applicable in fast-track patients receiving early mobilisation is uncertain.
Studies on fast-track patients receiving early mobilisation and thrombosis prophylaxis only during hospitalisation showed very small incidence of symptomatic thromboembolic events. Therefore we conduct a quality-cohort-study on all patients receiving fast-track TKR/THR with short-term anti-thrombotic treatment, in order to investigate frequency of symptomatical deep vein thrombosis, pulmonary embolus, acute myocardial infarction and stroke.

Questions about this trial
What is this clinical trial studying?
An observational study of Thromboembolic Events and Post-operative Bleeding, run by Copenhagen University Hospital, Rigshospitalet at 6 sites in Denmark.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 6 sites in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Frequency of Vascular events (time frame: 90 days postop). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01557725, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jan 2021; AzTrials last refreshed its copy on 7 Nov 2026.
