Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Aim:
To determine whether chemical neurolysis of the genicular nerves with 6% aqueous phenol is non-inferior in reducing knee pain as compared to corticosteroid injection of the genicular nerves, in patients with refractory chronic knee pain for more than 6 months after total knee replacement.
Hypothesis:
Chemical neurolysis of genicular nerves with phenol will provide equal or superior pain relief than corticosteroid genicular nerve injections at 3 months, as measured by the Oxford Knee Score.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Treatment Group: Phenol injection
6% aqueous phenol 2.5 mL will be mixed with 0.5 mL iopamidol 300 and will be injected at each target sites
Phenol Injection
6% aqueous phenol 2.5 mL will be mixed with 0.5 mL iopamidol 300 and will be injected at each target site with live, pulsed fluoroscopy (5-8 seconds at each location) to observe the contrast dye-tagged phenol covering the lateral margin of the femur or tibia respectively on AP and lateral views. The needles will then be removed and band-aids placed.
Control Group: Methylprednisolone injection
Methylprednisolone acetate 10 mg with 2 mL preservative free saline and 0.5 mL iopamidol 300 will be injected at each of the target site
Methylprednisolone Injection
Methylprednisolone acetate 10 mg with 2 mL preservative saline and 0.5 mL iopamidol 300 will be injected at each of the 3 target sites with live, pulsed fluoroscopy (5-8 seconds at each location) to observe the contrast dye-tagged steroid mixture covering the lateral margin of the femur or tibia respectively on AP and lateral views; the needles will be removed and band-aids placed.
