Multivariable Postoperative Outcomes and Complications of Nerve Ablation Before TKA and Control-TKA

Category	Total	GNRFA-TKA	Control-TKA
	Odds Ratio	95% CI		P
Anemia	0.170	0.111-0.249		<0.001
Atrial fibrillation	0.517	0.366-0.731		<0.001
Arrhythmia without atrial fibrillation	0.274	0.157-0.478		<0.001
Blood transfusion	0.338	0.144-0.662		0.005
UTI	0.250	0.166-0.366		<0.001
Prolonged opioid use	0.478	0.409-0.559		<0.001

GNRFA = genicular nerve radiofrequency, TKA = total knee arthroplasty, UTI = urinary tract infection.

Ablation significance at P < 0.05 is presented in bold.
