Adequate pain control after total hip arthroplasty is crucial for early ambulation and patient satisfaction. However, there is no consensus about optimal pain control after post operation. In general, the periarticular multimodal durg injection block has been done for pain control in primary total hip arthroplasty. 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 is possible to provide sufficient analgesia and preserve lower limb muscle strength. The investigators will compare PENG and PMDI block with isolated PMDI block in patients undergoing total hip arthroplasty.
