Study Arms (2)
TIBIAL group
EXPERIMENTALAll patients allocated to the TIBIAL group will receive an adductor canal block with 20ml of ropivacaine 0.75% and a selective tibial nerve block with 5 ml of ropivacaine 0.75% prior to surgery,
IPACK group
ACTIVE COMPARATORAll patients allocated to the IPACK group will receive an adductor canal block with 20ml of ropivacaine 0.75% and an IPACK with 20ml of ropivacaine 0.2% prior to surgery.
Interventions
The selective tibial nerve block will be performed on the popliteal crease following sterilization of the area. The probe will be placed in a transverse position at the popliteal crease to visualize the popliteal artery and the tibial nerve in short axis. A 21-gauge 50mm insulated facet tip needle (SonoPlex® STIM, Pajunk, Geisingen, DE) will be inserted in-plane with the ultrasound bean from a medial to lateral direction. Once the needle tip is adjacent to the tibial nerve, 5 ml of ropivacaine 0.75% will be injected to achieve an adequate spread of local anaesthetics around the nerve.
The IPACK will be performed on the popliteal crease following sterilization of the area. The probe will be placed in a transverse position proximal to the popliteal crease to visualize the popliteal artery in short axis. A 21-gauge 100 mm insulated facet tip needle (SonoPlex® STIM, Pajunk, Geisingen, DE) will be inserted in-plane with the ultrasound beam, in a lateral to medial direction, between the popliteal artery and the posterior capsule, where twenty mL of ropivacaine 0.2% will be injected under ultrasound guidance. The distribution of local anaesthetics will be observed above the posterior capsule.
