Analgesic effect of lateral femoral cutaneous nerve block to the pericapsular nerve group (PENG) block in primary total hip arthroplasty: a randomized clinical trial

Adequate hip joint and surgical incision analgesia represent a challenge in the postoperative period of primary total hip arthroplasty (THA). This study aimed to evaluate whether the combination of the lateral femoral cutaneous nerve block (LFCN block) and the pericapsular nerve group block (PENG block) influences postoperative analgesia and rescue opioids, in primary THA surgeries.
