Outcome Measures

Primary Outcomes (1)

  • The effect of the popliteal plexus block (PPB)

    Evaluated as the percentage of patients with postoperative pain NRS \>3, dropping in pain score to NRS ≤ 3 after the PPB

    Pain scores (NRS): 15, 30, 45 and 60 minutes after PPB

Secondary Outcomes (4)

  • Percentage of patients with central knee pain

    Pain scores: 15, 30, 45 and 60 minutes after arrival at the post anesthesia care unit (PACU)

  • Onset time for PPB

    Pain scores (NRS): 15, 30, 45 and 60 minutes after PPB

  • The effect of the PPB on cutaneous sensation

    Baseline, 30 and 60 minutes after PPB

  • The effect of the PPB on muscle strength

    Baseline, 60 minutes after PPB

Study Arms (2)

Patients with postoperative pain, NRS >3

EXPERIMENTAL

Patients reporting postoperative pain (NRS \>3) localized to the center of the knee (10 patients) will receive a popliteal plexus block

Procedure: Popliteal plexus block

Patients with postoperative pain, NRS ≤ 3

NO INTERVENTION

(approx. 90 patients)

Interventions

10 mL Marcain-adrenalin 5 mg/mL + 5 microgram/mL. Ultrasound-guided injection into the distal part of the adductor canal

Patients with postoperative pain, NRS >3
