Pericapsular Nerve Group (PENG) Block Versus Periarticular Injection for Pain Management After Total Hip Arthroplasty
A study testing Pericapsular nerve group block and Periarticular block in people with Total Hip Arthroplasty and Postoperative Pain, run by Yonsei University at 1 site in South Korea.
Trial summary
Adequate pain control after total hip arthroplasty is crucial for early ambulation and patient satisfaction. The pericapsular nerve group (PENG) block has been recently introduced a new technique for blockade of the articular branches of the femoral, obturator and accessory obturator nerves.

About this study
Official title: Pericapsular Nerve Group (PENG) Block Versus Periarticular Injection for Pain Management After Total Hip Arthroplasty: a Randomized Controlled Trial
Adequate pain control after total hip arthroplasty is crucial for early ambulation and patient satisfaction. The pericapsular nerve group (PENG) block has been recently introduced a new technique for blockade of the articular branches of the femoral, obturator and accessory obturator nerves. PENG block provides sufficient analgesia but it is still the potential for quadriceps weakness that might delay ambulation. Periarticular injection has attached attention as an effective analgesic modality with a low prevalence of adverse effects. The investigators will compare ultrasound-guided PENG block with periarticular injection in patients undergoing total hip arthroplasty.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Pericapsular nerve group blockProcedure or surgery
Also called PENG block
A curvilinear 2-5MHz ultrasound probe will be initially placed in a transverse plane over the anterior superior iliac spine and then aligned with the pubic ramus by rotating the probe counterclockwise approximately 45 degrees. In this view, the iliopubic eminence, the iliopsoas muscle and tendon, the femoral artery, and pectineus muscle will be observed. A 22-gauge, 80-mm needle will be inserted from lateral to medial in an in-plane approach to place the tip in the musculofascial plane between the psoas tendon anteriorly and the pubic ramus posteriorly. A total volume of 20 ml of ropivacaine 0.3% will be injected.
Periarticular blockProcedure or surgery
The periarticular injection solution contained 20mL of 7.5 mg/mL ropivacaine, 30mg of ketorolac, and 0.3mL of 1.0 mg/mL epinephrine. These agents were mixed with normal saline to a combined volume of 50mL. The surgeon injected this mixture into the tensor fascia lata, subcutaneous tissues, abductors, short external rotators muscles, and structures in the capsule.

What is being measured
The primary outcome is the main question the study is designed to answer.
Numeric rating scale pain score
Pain intensity at rest evaluated by an 11-point numeric rating scale (NRS: 0 = no pain, 10 = worst imaginable pain) at 24 hours postoperatively
Measured: at 24 hours postoperatively
Secondary outcomes (2)
Numeric rating scale pain score
Pain intensity at rest evaluated by an 11-point numeric rating scale (NRS: 0 = no pain, 10 = worst imaginable pain) at 6 hours postoperatively and 48h postoperatively
Measured: at 6 hours postoperatively and 48h postoperatively
Quadriceps muscle strength
Quadriceps muscle strength will be measured by the dynamometer at 24h postoperatively
Measured: at 24 hours postoperatively

Clinical summary

The pericapsular nerve group (PENG) block has been recently introduced a new technique for blockade of the articular branches of the femoral, obturator and accessory obturator nerves. PENG block provides sufficient analgesia but it is still the potential for quadriceps weakness that might delay ambulation. Periarticular injection has attached attention as an effective analgesic modality with a low prevalence of adverse effects.
