Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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)
