Clinical Trial Summary

This randomised clinical trial evaluates the analgesia provided by an iPack block associated with an adductor canal block in patients who undergo anterior cruciate ligament reconstruction surgery, compared to an adductor canal block alone. The objective is to prove the superiority of this locoregional anesthesia in terms of analgesia and functional rehabilitation.

Description:

The ideal loco-regional anesthesia for anterior cruciate ligament reconstruction ensuring a satisfying analgesia without compromising an early rehabilitation is still undetermined.

Femoral nerve block has been incriminated in a delayed postoperative mobilization whereas the adductor canal block gives an equivalent analgesia for a better preservation of the quadricipital muscular strength.

The iPACK block (infiltration between the popliteal artery and the capsule of the posterior knee) is a recently described technique. Few studies have assessed the iPACK block in ACL reconstruction, and none were randomized.

This randomized single blind clinical trial compares two groups of 45 patients who undergo ACL reconstruction surgery under general anaesthetic : one receives an iPACK block associated with an adductor canal block, and the other only has an adductor canal block.

Pain scores and opioid consumption are collected after surgery in the recovery room, then by telephone interview at 24 and 48 hours post-surgery. Functional rehabilitation is evaluated by scales (KOOS, LYSHOLM and iKDC) at 3, 6 and 9 months after surgery. Adverse effects, due to anesthesia or opioids, are collected from 30 min after loco-regional anesthesia until the second phone call at 48h post-surgery.
