  Purpose
Total knee replacement is very common in Germany. After surgery patients have severe pain in the knee; initiation of the physiotherapy, however, is important in the first three days after surgery. Continuous femoral blockade and continuous (lumbar) epidural analgesia are commonly used after surgery. Both methods are used in Germany. Both methods have advantages and disadvantages. We wanted to answer the question which method of analgesia - after total knee replacement - is better concerning complications and function (after 3 months) ?

Arms Assigned Interventions
Active Comparator: Femoral Block
One group received a femoral block for analgesia after surgery. Ropivacain was administered continuously for three days.
Device: Femoral catheter
Femoral catheter was inserted at the beginning of surgery. After surgery ropivacaine was administered continuously for three days. In addition, patients received piritramide via patient-controlled analgesia. The amount of ropivacaine was measured.
Active Comparator: Epidural Analgesia
One group received an epidural analgesia after surgery for three days.
Device: Epidural catheter
The epidural catheter was inserted at the beiginning of surgery. After surgery ropivacaine was applied continuously for three days. In addition, patients received piritramide via patient controlled analgesia. The amount of ropivacaine was measured.
