Biochemical Approach to Measuring Surgical Trauma

September 16, 2014 updated by: Anthony Adili, Hamilton Health Sciences Corporation

Further Development of a Biochemical Approach to Measuring Surgical Trauma to Musculoskeletal Tissues

This study will examine the magnitude and time course of changes in circulating (serum and plasma) biomarker concentrations associated with musculoskeletal injury created by total knee replacement surgery. The sensitivity to injury will be characterized by the changes in mean serum concentration before and after surgery. Specificity for the injured state will be evaluated comparing the baseline to peak change (injury response) with the pre-surgery to follow-up baseline fluctuation (i.e. measurement noise).
