About

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.
