Further study details as provided by Glostrup University Hospital, Copenhagen:

Primary Outcome Measures:
  • Pain-Score (VAS) - patient standing [ Time Frame: 2 hours postoperative ]
    Pain-score messured on a Visual Analog Scale (VAS) 2 hours after adductor canal block. Patient standing. Intervention-group vs. placebo-group.


Secondary Outcome Measures:
  • Pain-score (VAS), patient at rest [ Time Frame: 0,1,2,4,6,8,24 hours postoperative ]
    ACB-group vs. placebo

  • Pain-score (VAS), patient standing [ Time Frame: 1,2,4,6,8,24 hours postoperative ]
    ACB-group vs. placebo

  • Pain-score (VAS), after 5 meters of walk [ Time Frame: 2,4,6,8,24 hours postoperative ]
    ACB-group vs. placebo

  • Total Opioid-consumption [ Time Frame: 0-24 hours postoperative ]
    ACB-group vs. placebo-group

  • Opioid-consumption, postoperative [ Time Frame: 0-2, 2-4, 4-6, 6-8, 8-24 hours postoperative ]
    i.v. morfin 0-2 hours postoperative tbl. morfin 2-24 hours postoperative ACB vs. placebo

  • Postoperative Nausea and vomiting [ Time Frame: 0-1, 1-2, 2-4, 4-6, 6-8, 8-24 hours postoperative ]
    Rating-scale 0-3 ACB-group vs. placebo-group

  • Postoperative ondansetron consumption [ Time Frame: In-hospital ]
    ACB-group vs. placebo-group

  • Sedation [ Time Frame: 0,1,2,4,6,8,24 hours postoperative ]
    Rating-scale: 0-3 ACB-group vs. placebo-group
