original publication.
This study has been identified as potentially high impact.
OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself.
Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone.
This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.
Faster recovery without the use of a tourniquet in total knee arthroplasty
Acta Orthop. 2014 Aug;85(4):422-6. doi: 10.3109/17453674.2014.931197. Epub 2014 Jun 23.70 patients with stage 3-5 gonarthrosis were randomized to undergo total knee arthroplasty (TKA) with or without the application of a tourniquet. The purpose of this trial was to determine whether TKA should be performed with or without the use of a tourniquet, based on functional and clinical outcomes at one year postoperatively. Results revealed that TKA without the use of a tourniquet significantly improved KOOS functional outcomes and knee range of motion up to 8 weeks after surgery, but resulted in greater intraoperative bleeding compared to TKA using a tourniquet. However, neither group required transfusion following TKA.
