Summary

Total knee arthroplasty (TKA) is one of the most common orthopedic surgical procedure and is associated with severe pain in the immediate postoperative period, thus limiting early recovery.

Postoperative pain management requires multimodal analgesia, combining drugs and injection of a local anesthetic (LA). For optimal pain management, several peripheral nerve blocks should be associated. Thus, a recent study shows that the combination of IPACK, femoral triangle and obturator nerve blocks (ITO blocks) provides an effective pain control after TKA.

The hypothesis of this study is that a quadruple nerve block combining femoral, sciatic, obturator and lateral femoral cutaneous nerve blocks (quadri-block) could improve analgesia after TKA.

The main objective of this monocenter, prospective, randomized, open-label, controlled trial is to assess the effect of quadri-block on morphine consumption after TKA compared to ITO blocks.

Conditions

  • Primary Total Knee Arthroplasty

Interventions

PROCEDURE

IPACK

25 milliliters of ropivacaine 0.3% will be injected between popliteal artery and femur.

PROCEDURE

Femoral triangle block

25 milliliters of ropivacaine 0.3% will be injected on the lateral side of the femoral artery at the distal part of the femoral triangle.

PROCEDURE

Obturator nerve block

20 milliliters of ropivacaine 0.3% will be injected between the adductor magnus and adductor brevis muscles and between the adductor brevis muscle the pectineus.

PROCEDURE

Femoral nerve block

20 milliliters of ropivacaine 0.3% will be injected in supine position under the fascia iliaca lateral to the femoral artery.

PROCEDURE

Sciatic nerve block

25 milliliters of ropivacaine 0.3% will be injected in prone position in the subgluteal space by lateral approach.

PROCEDURE

Lateral femoral cutaneous nerve block

5 milliliters of ropivacaine 0.3% will be injected laterally to the sartorius muscle.
