Up to 80% of patients experience significant residual limb pain (RLP) and phantom limb pain (PLP) following amputation, and generally respond poorly to conventional therapies. Percutaneous ablation has emerged as a promising intervention for both RLP and PLP pain. We sought to systematically review and evaluate the efficacy and adverse outcomes of thermal radiofrequency ablation (RFA), pulsed RFA, and cryoablation in the treatment of post-amputation pain.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Medline, Embase, PubMed, and Scopus databases were systematically search on August 19, 2024 for all English language articles related to post-amputation pain treated with an ablation technique.
