Management of post-arthroplasty pain: a narrative review of emerging interventional treatments.

Abstract

Total joint arthroplasties are one of the most common orthopedic procedures with over 1 million total hip and knee arthroplasties performed annually. While the majority of patients experience favorable long-term outcomes, a significant number of patients continue to report persistent pain more than 3 months post-arthroplasty that is unresponsive to conservative treatment. Although current treatment options may seem limited, there are a variety of innovative procedures for the management of post-arthroplasty pain with the overall goal of reducing pain and restoring function. In this review, we outline the work-up for persistent post-arthroplasty pain and provide a review of the literature on interventional treatment modalities consisting of intra-articular steroids, radiofrequency ablation, and neuromodulation for the management of chronic post-arthroplasty pain in the hip, knee, ankle, and shoulder.
