This study evaluates the pathophysiological effects of a single dose methylprednisolone administered prior to total knee-arthroplasty surgery (TKA). The investigators examine the effect on the endothelial glycocalyx shedding due to surgical trauma. Half of participants will receive intravenous Solu-Medrol 125 mg, while the other half will receive placebo. The investigators hypothesize that the group receiving methylprednisolone will experience reduction in glycocalyx degradation compared to the placebo-group, early after TKA.

Clinical Details

Official title: Effect of Preoperative Intravenous High Dose Methylprednisolone on Endothelial Function in Patients Scheduled for Total Knee-arthroplasty

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)

Primary outcome: Change in plasma Syndecan-1 from baseline (before surgery) to 24 hours after surgery

Secondary outcome:

Change in plasma soluble Thrombomodulin from baseline (before surgery) to 24 hours after surgery

Change in plasma SE-Selectin from baseline (before surgery) to 24 hours after surgery

Change in plasma VE-Cadherin from baseline (before surgery) to 24 hours after surgery

Detailed description: The anti-inflammatory effects of glucocorticoids are well known. The beneficial effects on postoperative pain, postoperative nausea and vomiting are well-documented. Postoperatively, activation and / or dysregulation of the inflammatory system influence on the endothelial glycocalyx. Damage of the vascular endothelia increases the risk of cardiovascular and thromboembolic complications. In animal studies glucocorticoids have been found to preserve the endothelial glycocalyx and the vascular barrier. The effect of glucocorticoids on human endothelial glycocalyx after surgery is unknown and calls for further investigation. This study is embedded in a primary study registrated as: NCT02319343 For further details please view the EudraCT registration: EudraCT nr.: 2014-003395-23
