简要总结
The study aims to investigate the effect of the Popliteal plexus block (PPB) on postoperative pain after total knee arthroplasty
详细描述
Cadaver dissection studies have shown a spread of dye to the popliteal fossa and colored the popliteal plexus by injecting in the distal part of the adductor Canal.
The popliteal plexus is formed by contribution from the tibial and the obturator nerves.
Investigators hypothesized that a PPB may reduce postoperative pain after total knee arthroplasty.

研究组 & 干预措施
Popliteal plexus block
Patients with an FTB, reporting postoperative pain (NRS > 3) will have a popliteal plexus block
干预措施: Bupivacaine-epinephrine (Drug)
结局指标
主要结局
The percentage of patients with postoperative pain NRS
时间窗: 0 - 60 minutes
Evaluated as the percentage of patients with postoperative pain NRS \>3, dropping in pain score to NRS = or \< 3 after the PPB
次要结局
- 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))
- Turn off time of spinal anesthesia(Time 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))
- The effect of the PPB on muscle strength of the foot(Baseline and 1 hour after PPB)
- Onset time of PPB(NRS every 5 minutes after PPB (From 0 - 60 minutes after PPB))
- Correlation between normal cutaneous sensation and developing of pain(From arrival in PACU and during maximum 6 hours)
