Clinical Trial Summary

A lot of patient have posterior knee pain after ACL reconstruction despite saphenous nerve block. Recently a new block has been described, know as IPACK block (interspace between the popliteal artery and the capsule of the posterior knee). The objective of this randomized controlled double-blinded trial is to assess whether a combined saphenous nerve block with IPACK block is more effective for the postoperative pain than a local infiltration analgesia.

Description:

The saphenous nerve and the iPACK will be performed after general anaesthesia induction and before the surgery under ultrasound-guidance. The local infiltration analgesia will be performed by the surgeon during the surgery.
