Groups/Cohorts
Total knee arthroplasty
Patients operated with elective, unilateral total knee arthroplasty.

Detailed Description:

The correlation between acute pain and systemic inflammatory markers after total Knee Arthroplasty (TKA) is evaluated.

Level of systemic inflammatory markers (CRP and IL6) are measured preoperatively and 4 and 24 hours postoperatively. These measurements are correlated to postoperative pain (a detailed assessment of pain at rest and during ambulation).

We pole blood-samples collected prospectively (from two data set)
