Brief summary

A clinical trial investigating the effect of a combined locoregional anesthesia technique on the postoperative analgesia outcomes after a total hip arthroplasty. A PENG block will be used in combination with a LFCN block. The results will be compared to a control group that is solely treated with intravenous analgesia. This technique aims to provide improved pain scores after surgery without interference of revalidation.
