Conditions

Gonarthrosis, Total Knee Arthroplasty

Brief summary

The aim of this study is to evaluate the analgesic efficacy of this quadruple sensory block compared with the currently recommended procedure (adductor canal block + infiltration).

Detailed description

In addition to the adductor canal block, this quadruple block incorporates : 1. the block of the lateral cutaneous nerve of the thigh (or femoral-cutaneous nerve), which is a collateral sensory branch of the posterior part of the lumbar plexus. 2. IPACK (Infiltration between Popliteal Artery and Capsule of Knee), designed as a motor-sparing technique (targeting the sensory articular branches of the sciatic nerve and avoiding the motor branches of the tibial and fibular nerves), is particularly effective on posterior pain. 3. obturator nerve block, a mixed nerve originating from the anterior part of the lumbar plexus. It divides into two branches: anterior, which innervates the adductor longus, adductor brevis and gracilis muscles, and posterior, which innervates the medial part of the knee joint and the posteromedial part of the thigh. It provides sensitivity to the medial aspect of the thigh.

Intervention model description

Category 2 Research Involving the Human Person (RIPH 2) : Multi-center (2 sites), prospective, double-blind randomized, study of two parallel groups of patients undergoing total knee arthroplasty according to locoregional analgesia (LRA) protocol : * Group 1: Real adductor canal block + surgical infiltration and sham of femoro-cutaneous block + obturator block + IPACK block with physiological serum * Group 2: Real adductor canal block + femoro-cutaneous block + obturator block + IPACK block and sham of surgical infiltration with physiological serum

Design outcomes

Primary

MeasureTime frameDescription
Patient's recovery at H24 as after surgery assessed by the QoR-15 (Quality of Recovery) questionnaire scoreFrom enrollement to the last H24 after surgeryThe QoR-15 score at H24 after surgery was compared between the two groups for primary endpoint analysis. The QoR-15 accurately measures postoperative recovery by focusing on 5 key domains: pain, physical comfort, physical independence, psychological support and emotional state. Each item is rated from 0 (unfavorable) to 10 (favorable), with an overall score corresponding to the sum of the score obtained for each item, i.e. a score from 0 (no recovery) to 150 (full recovery).
