To support our hypothesis that preoperative quadratus lumborum block (QLB)/lateral femoral cutaneous nerve block (LFCNB) provides more effective analgesia than periarticular injection (PAI) in total hip arthroplasty (THA), we will look at the following outcomes:~Primary outcome: Daily opioid consumption~Secondary outcomes:~Pain intensity and physical functioning while in the hospital: using pain inventory modified from Brief Pain Inventory and Length of hospital stays.~Since both QLB/LFCNB nerve block and PAI techniques are both routinely used as standard of care anesthesia for THA, the study intervention will be the randomization to assign patients to one of these treatment options and assess their response from post-op patient questionnaires and data collection.~When results were entered, the detailed description was updated to reflect the outcome measures used in the study.
This study will assess if preoperative quadratus lumborum block (QLB)/lateral femoral cutaneous nerve block (LFCNB) with ropivacaine and glucocorticoids provide more effective analgesia than periarticular injection (PAI) with the same mixture in total hip arthroplasty (THA).
