About

This study aims to compare the analgesic efficacy and functional outcomes of blocking the nerve to the vastus lateralis (NVL) muscle versus the lateral femoral cutaneous nerve (LFCN).

Full description

Knee surgeries are associated with significant postoperative pain, which can impede early mobilization and prolong recovery. Recent advancements in ultrasound-guided regional anesthesia have enabled more targeted nerve blocks, such as the blockade of the nerve to the vastus lateralis (NVL) and the lateral femoral cutaneous nerve (LFCN)
