Brief Summary

Total knee replacement surgery is commonly performed for patients suffering from severe knee osteoarthritis. However, 20% of patients continue to experience pain after surgery. There is currently no standardized pain management protocol for pain after total knee replacement. Cooled radiofrequency ablation has been used successfully to alleviate spin-related pain and has recently been approved by the FDA to treat chronic knee arthritic pain. This pilot study aims to collect preliminary data on the use of cooled radiofrequency ablation in patients undergoing total knee replacement.

Outcome Measures

Primary Outcomes (1)

  • Pain

    Pain will be assessing on a 0-10 scale, where 0=no pain and 10=most pain.

    Up to 1 year post-total knee replacement

Secondary Outcomes (2)

  • Knee Disability

    Up to 1 year post-total knee replacement

  • Function assessed using the PROMIS-physical function computer adaptive test

    Up to 1 year post-total knee replacement

Study Arms (1)

Preoperative cooled radiofrequency ablation

Patients who undergo cooled radiofrequency ablation within 4-8 weeks of their scheduled total knee replacement.

Procedure: Total knee replacementDevice: COOLIEF

Interventions

Patients will undergo total knee replacement surgery.

Preoperative cooled radiofrequency ablation
COOLIEFDEVICE

The superior lateral genicular nerve, superior medial genicular nerve, and inferior medial geniculate nerve will be ablated.
