Outcome Measures

Primary Outcomes (1)

  • The percentage of patients with postoperative pain NRS

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

    0 - 60 minutes

Secondary Outcomes (6)

  • Percentage of patients having a femoral triangle block(FTB) reporting NRS > 3

    Pain scores every 15 minutes (from end injection FTB to NRS>3 or 3 hours after full sensation of the leg)

  • Onset time of PPB

    NRS every 5 minutes after PPB (From 0 - 60 minutes after PPB)

  • Turn off time of spinal anesthesia

    Time from arrival in PACU and during maximum 6 hours

  • Correlation between normal cutaneous sensation and developing of pain

    From arrival in PACU and during maximum 6 hours

  • The effect of the PPB on cutaneous sensation

    NRS every 5 minutes after PPB (From 0 - 60 minutes after PPB)

  • +1 more secondary outcomes

Study Arms (2)

Popliteal plexus block

EXPERIMENTAL

Patients with an FTB, reporting postoperative pain (NRS \> 3) will have a popliteal plexus block

Drug: Bupivacaine-epinephrine

No intervention

NO INTERVENTION

Patients with postoperative pain NRS \< or = 3

Interventions

Popliteal plexus block with 10 mL of bupivacaine-epinephrine 5 mg/mL + 5 microgram/mL.

Popliteal plexus block
