Is there a need to modify the anatomical targets for genicular nerve ablation in prosthetic knees compared with native knees? A cadaveric study

Prosthetic knees share comparable genicular nerve anatomic locations with native knees but exhibit smaller nerve diameters and fibrosis of the IPBSN. The absence of a nearby arterial branch to the SLGN may reduce ultrasound targeting accuracy. Anatomical differences alone, however, do not fully explain the diminished pain relief observed after radiofrequency ablation.
