    0-100 mm at a visual analogue scale (VAS), at 4 hours postoperative.

    Time frame: 4 hours postoperative

Secondary outcomes

  1. Pain during 45 degrees active flexion of the knee

    0-100 mm at a visual analogue scale (VAS), registered at the intervals 1, 2, 4, 6 and 8 hours postoperative, calculated as "the area under the curve" (AUC) for the interval 1-8 hours postoperative.

    Time frame: 1-8 hours postoperative

  2. Pain during 45 degrees active flexion of the knee

    0-100 mm at a visual analogue scale (VAS), at 24 hours postoperative.

    Time frame: 24 hours postoperative

  3. Pain during rest

    0-100 mm at a visual analogue scale (VAS), registered at the intervals 1, 2, 4, 6 and 8 hours postoperative, calculated as "the area under the curve" (AUC) for the interval 1-8 hours postoperative.

    Time frame: 1-8 hours postoperative

  4. Pain during rest

    0-100 mm at a visual analogue scale (VAS), at 24 hours postoperative.

    Time frame: 24 hours postoperative

  5. Total morphine consumption

    Total morphine consumption at the intervals 0-8, 8-24 and 0-24 hours postoperative.

    Time frame: 0-24 hours postoperative

  6. Postoperative nausea

    Nausea scores(0-3)registered at 1,2,4,6 and 8 hours postoperative, calculated as mean value for the interval 1-8 hours postoperative.

    Time frame: 1-8 hours postoperative

  7. Postoperative nausea

    Nausea score(0-3)at 24 hours postoperative.

    Time frame: 24 hours postoperative

  8. Postoperative vomiting

    Number of vomiting episodes at the intervals 0-8, 8-24 and 0-24 hours postoperative.

    Time frame: 0-24 hours postoperative

  9. Zofran consumption

    Total zofran consumption at the intervals 0-8, 8-24 and 0-24 hours postoperative.

    Time frame: 0-24 hours postoperative
