Genicular Radiofrequency Ablation Following Total Knee Arthroplasty

After the cannulae are placed and tines deployed, a single lesion (30 second ramp-up time; 80C x 2 minutes) will be made at each of the medial and lateral branches of the nerve to the vastus intermedialis, nerves to the vastus lateralis and medialis, recurrent fibular nerve, inferior medial genicular nerve. One bipolar strip lesion (intercannula distance 1.5 cm; anticipated strip lesion length 2.0 cm) at the superior medial and lateral genicular nerves will be made to accommodate anatomical variability.
