Comparison of Ultrasound Guided Genicular Nerve Block and Periarticular Infiltration in Knee Arthroplasty
Comparison of Ultrasound Guided Genicular Nerve Block and Periarticular Infiltration for Postoperative Pain in Knee Arthroplasty
Effective pain relief allows the patients to obtain early knee mobilization and optimal rehabilitation and thus improves the patient satisfaction.
The aim of perioperative pain control is to minimize delays in recovery, postoperative delirium and pain-related stress responses that can lead to serious morbidity and poor outcomes. Numerous approaches to effectively control postoperative pain in TKA patients have been evaluated, as poorly controlled acute postoperative pain can be associated with persistent pain. Furthermore, increased pain intensity after surgery on the second knee seems to be closely associated with chronic post-TKA pain, with similar mechanisms underlying hyperalgesia or chronic pain.

Detaljeret beskrivelse
Total knee arthroplasty (TKA), one of the most commonly performed operations in orthopaedic department, has been a successful intervention for patients with end-stage knee arthritis.
Rehabilitation after total knee arthroplasty (TKA) routinely starts immediately after surgery on the postoperative ward and therefore requires adequate analgesia. An ideal analgesic modality for post-TKA rehabilitation should permit adequate knee flexion with minimal pain without motor impairment, resulting in successful mobilization. Pain control plays an essential role in the overall postoperative period for the patients undergoing TKA.
Effective pain relief allows the patients to obtain early knee mobilization and optimal rehabilitation and thus improves the patient satisfaction.
The aim of perioperative pain control is to minimize delays in recovery, postoperative delirium and pain-related stress responses that can lead to serious morbidity and poor outcomes. Numerous approaches to effectively control postoperative pain in TKA patients have been evaluated, as poorly controlled acute postoperative pain can be associated with persistent pain. Furthermore, increased pain intensity after surgery on the second knee seems to be closely associated with chronic post-TKA pain, with similar mechanisms underlying hyperalgesia or chronic pain.
Traditionally, the degree of knee flexion has been used as an outcome measure after TKA to evaluate functional recovery and the success of the type of analgesia used.
Several methods such as intravenous opioids, extraarticular and intraarticular injection, epidural analgesia and femoral or sciatic nerve blocks are currently used for postoperative pain management.
However, each method is reported with potential side effects, for example, opioid drugs caused vomiting, nausea, constipation, dizziness and urinary retention, epidural analgesia with urinary retention, respiratory depression and spinal headache, femoral or sciatic block with diminished muscle control and possible nerve damage.
Periarticular multimodal drug injection in TKA is a technique that patients received intraoperative drug injection in the periarticular fields such as posterior capsule, medial and lateral collateral ligaments, quadriceps mechanism and peripatellar tissue at the end of the surgery. Multimodal drugs mainly consist of local anaesthetics, non-steroidal anti-inflammatory drugs, opioids, epinephrine with or without corticosteroid.
Genicular nerve block (GNB) and ablation have been used for managing chronic pain from knee osteoarthritis with good success.

Eksperimentel: periarticular infiltration group
will receive intraoperative periarticular infitration consisting of 89.5 mL of normal saline, 20 mL of 5% bupivacaine and 0.5 mL of adrenaline (4.5 ugm/ml) with a concentration 1:220000 (total volume: 110 mL)
|
The cocktail will be injected at the following 7 anatomical zones as follows: Zone 1: medial retinaculum Zone 2: medial collateral ligament and medial meniscus capsular attachment Zone 3: posterior capsule Zone 4: lateral collateral ligament and lateral meniscus capsular attachment Zone 5: lateral retinaculum Zone 6: patellar tendon and fat pad Zone 7: cut ends of quadriceps muscle and tendon Injection at zones 2, 3, and 4 will be administered after making the tibial and femoral cuts and ligament balancing. At zones 1, 5, 6, and 7, the injection will be administered after implant placement. |
|
Eksperimentel: genicular nerve block group
will receive ultrasound guided genicular nerve block at three nerves, i.e., superomedial, superolateral, and inferomedial genicular nerves consisting of 15 ml bupivacaine 0.25% with adrenaline 2.5 µg/ml with a concentration 1:400000 in the immediate postoperative period.
|
The genicular arteries will be identified near the periosteal areas, which are the junctions of the epicondyle and the shafts of the femur and tibia, and confirmed by color Doppler ultrasound.
genicular nerve block target points should be next to each genicular artery because the superior lateral, superior medial, and inferior medial genicular artery traveled along each genicular nerve.After using color Doppler to confirm the genicular artery, the needle will be inserted in the plane of the ultrasound probe in the long-axis view.
