AbstractTotal knee arthroplasty is a common and successful treatment modality for knee arthritis that is refractory to conservative management strategies. Over 600,000 arthroplasties are performed per year in the United States, and this number is expected to increase in the coming years. Unfortunately, 8% to 34% of patients experience chronic pain after having a total knee arthroplasty. These patients should undergo an appropriate work-up by the orthopedic surgeon, but many times a surgical problem is not uncovered. In these situations, a thorough and specific plan for pain management should be sought. In this article, we outline the work-up of a painful total knee arthroplasty. Then we provide a thorough review of interventional pain management strategies and highlight the pertinent literature. Lastly, we hypothesize future developments in the field that may provide better outcomes for patients suffering from painful total knee arthroplasty.© 2020 World Institute of Pain.
