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. 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.

Conditions

• Total Hip Arthroplasty
• Postoperative Pain

Interventions

Type	Name	Description
PROCEDURE	Pericapsular nerve group 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.
PROCEDURE	Periarticular block	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.
