NCT01922596

Brief Summary

The purpose of the study is to compare the effect of a Adductor Canal Blockade (ACB) vs a Femoral Nerve Blockade (FNB), on muscle strength, mobility and pain in patients with severe pain (VAS pain score \> 60) after Total Knee Arthroplasty (TKA.

Outcome Measures

Primary Outcomes (1)

  • Change i muscle strength of the quadriceps muscle, after the blockade

    Maximum Voluntary Isometric Contraction (MVIC) of the quadriceps femoris muscle will be measured before and 2 hours after the blockade. The change will be compared between the groups. At each measuring point three measurements will be made and the average of these used.

    0 and 120 minutes

Secondary Outcomes (4)

  • muscle strength, adductor muscles

    0 and 120 minutes

  • Timed Up and Go (TUG)test

    0 and 120 minutes

  • VAS pain scores at rest

    0 and 120 minutes

  • Pain during passive flexion of the knee

    0 and 120 minutes

Study Arms (2)

Active FNB, placebo ACB

EXPERIMENTAL

FNB with 30 ml of ropivacaine 0,2% and ACB with 30 ml of placebo (saline). The ACB will be performed just prior to the FNB. The blockades will be performed just after obtaining the baseline values (outcome measures) at time 0.
