Prediction of Pain in Total Knee Arthroplasty
Completed
- Conditions
- Pain, Postoperative
- Interventions
- Procedure: Preoperative heat stimulation
- Registration Number
- NCT01179204
- Lead Sponsor
- Hvidovre University Hospital
- Brief Summary
In this consecutive, prospective cohort study trial the investigators evaluate if preoperative pain response upon heat stimulation is predictive for acute and subacute postoperative pain after total knee arthroplasty.
- Detailed Description
The preoperative heat stimulation consists of short and long tonic heat stimulation. Pain response is evaluated with an electronic visual analog scale.
Furthermore the investigators evaluate other factors possibly predictable for acute and subacute postoperative pain after total knee arthroplasty - demographic factors, preoperative pain related factors, psychosocial factors (Hospital Anxiety and Depression Scale and Pain Catastrophizing Scale).
