Rates of knee arthroplasty after genicular nerve ablation: A retrospective study utilizing a large national database

This is the largest cohort study to identify rates of KA following GNA. We found that roughly one in eight patients in this cohort received TKA or UKA after GNA, suggesting that GNA may offer clinically meaningful symptom relief for patients with KOA, such that KA may be delayed or deferred. Causality for whether GNA delays or prevents KA cannot be established from this study. The cost effectiveness and surgical sparing efficacy of GNA for symptomatic KOA should be further explored.
