Twenty-Four-Hour Movement Behaviors in Adults and Older Adults before Total Knee Arthroplasty: a Study Based on Compositional Data Analysis.

PURPOSE OF THE STUDY This study aims to describe and analyze the age differences in the 24-hour movement behavior patterns among a sample of adults and older adults with end-stage knee osteoarthritis referred for total knee arthroplasty (TKA). MATERIAL AND METHODS A total of 86 patients referred for TKA were included in this study. Sleep duration, sedentary behavior (SB), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) were assessed using multi-day 24-hour raw data from wrist-worn accelerometers.

Optimal Route for Tranexamic Acid in Diabetics and Obese Patients Undergoing Primary Total Knee Arthroplasty - a Data from Randomized Study.

PURPOSE OF THE STUDY To determine the optimal strategy for tranexamic acid (TXA) administration in diabetic patients, smokers and obese patients (BMI > 30 kg/m2) undergoing primary total knee arthroplasty (TKA). MATERIAL AND METHODS The total of 400 consecutive patients indicated for primary TKA were randomised into 4 basic groups with different TXA administration regimens. Group 1 (IV1) had a single intravenous dose (15 mg TXA/kg) applied prior to skin incision.

Combined and intravenous administration of TXA reduces blood loss more than topical administration in primary total knee arthroplasty: A randomized clinical trial.

Aim: To determine the most effective administration of tranexamic acid (TXA) in patients with primary total knee arthroplasty (TKA).

Material And Method: We enrolled a total of 400 patients (154 men and 346 women) in this randomized trial (4 groups, each of 100 patients). The first group (IV1) had a single intravenous dose (15 mg TXA/kg) prior to skin incision.

Gender Differences in Contribution of Smoking, Low Physical Activity, and High BMI to Increased Risk of Early Reoperation After TKA.

Background: The reliable preoperative identification of patients at a high risk of early reoperations (<2 years after primary surgery) after total knee arthroplasty (TKA) could lead to adjustments of the surgical procedure and counseling, thus lowering the percentage of revision surgeries.

Methods: The unselected cohort consisted of 1885 patients (695 men and 1190 women) who underwent TKA implantation between September 2010 and April 2017 at a single tertiary orthopedic center. Multivariate patient similarity networks were applied to identify patient groups at a high risk of early reoperations based on 25 preoperative parameters.
