Regional Nerve Blocks in Primary Total Knee Arthroplasty: The Clinical Practice Guidelines of the American Association of Hip and Knee Surgeons, American Society of Regional Anesthesia and Pain Medicine, American Academy of Orthopaedic Surgeons, Hip Society, and Knee Society

The American Association of Hip and Knee Surgeons, The American Academy of Orthopaedic Surgeons (AAOS), The Hip Society, The Knee Society, and The American Society of Regional Anesthesia and Pain Medicine have worked together to develop evidence-based guidelines on the use of regional nerve blocks in primary total knee arthroplasty (TKA). The purpose of these guidelines is to improve the treatment of orthopedic surgical patients and reduce practice variation by promoting a multidisciplinary evidence-based approach to the use of regional nerve blocks following primary TKA.
