Spread of dye injectate in the distal femoral triangle versus the distal adductor canal: a cadaveric study

Abstract

Our findings suggest that an injection in the distal AC may be suboptimal for knee analgesia as it may spare the NVM, while an injection in the distal FT could provide greater analgesia to the knee but may result in undesirable motor blockade from spread to the nerve to vastus intermedius.
