An update on radiofrequency denervation for arthritis-related knee joint pain: a synthesis of the current evidence.

The article explores the spread of ultrasound-guided injectate from the adductor canal to the genicular branch of the posterior obturator nerve and the popliteal plexus. Topics include cadaveric study and the predictive value of genicular nerve blocks for cooled radiofrequency ablation outcomes in chronic knee pain due to osteoarthritis.
