简要总结
The study aims to investigate the effect of the popliteal plexus block (PPB) on postoperative pain in patients undergoing anterior cruciate ligament (ACL) reconstruction.
详细描述
Postoperative pain following ACL reconstruction can be alleviated with an ultrasound-guided femoral triangle block (FTB). However, it is the investigators' observation that 10-20 % of the patients still complain of intense pain localized in the center of the knee.
Cadaver dissection studies have shown that an injection into the distal part of the adductor canal will spread to the popliteal fossa, and one dissection study showed consistent spread to the popliteal plexus.
The study team hypothesized that a PPB will reduce the postoperative pain, when it is used as a supplement to the FTB in patients undergoing ACL reconstruction.

结局指标
主要结局
The effect of the popliteal plexus block (PPB)
时间窗: Pain scores (NRS): 15, 30, 45 and 60 minutes after PPB
Evaluated as the percentage of patients with postoperative pain NRS \>3, dropping in pain score to NRS ≤ 3 after the PPB
次要结局

- 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)
- Percentage of patients with central knee pain(Pain scores: 15, 30, 45 and 60 minutes after arrival at the post anesthesia care unit (PACU))
