Anatomical and Technical Considerations of "Dual Subsartorial Block" (DSB), A Novel Motor-sparing Regional Analgesia Technique for Total Knee Arthroplasty

Abstract
The modernization of arthroplasty has paved the way for the resurgence of ultrasound-guided regional analgesia (RA) techniques. The evolution of newer RA techniques aids in reducing postoperative pain considerably as well as facilitates early ambulation and discharge.
