NCT01037400

Last verified: September 2014
  Purpose

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).

Study Population

Forty men and women ages 18-75 undergoing unilateral (n = 20) or bilateral (n = 20) knee replacement surgery with no musculoskeletal injury requiring medical attention in the past 3 months or producing pain in the previous 2 weeks and no inflammatory disease other than osteoarthritis.

Criteria
