Among the six knees with possible neuropathic pain postoperatively, four had possible neuropathic pain preoperatively as well, while the remaining two patients had been classified as nociceptive pain preoperatively. Knees with possible neuropathic pain postoperatively had higher postoperative NRS scores than those with nociceptive pain. Although the prevalence of possible neuropathic pain decreased significantly after TKA, the preoperative presence of possible neuropathic pain might be associated with the development of persistent postoperative pain following TKA. Although the prevalence of possible neuropathic pain decreased significantly after TKA, the preoperative presence of possible neuropathic pain might be associated with the development of persistent postoperative pain following TKA. Scoping reviews address the nature of the literature per se rather than inferring evidence-based treatment guidelines. Scoping reviews of the published literature are intended to describe the aggregated nature of the evidence surrounding some agent or intervention, in contrast to systematic reviews that seek when possible to guide clinical practice. We conducted a scoping review to identify reports of potential clinical utility of off-label topical analgesics and adjuvants when FDA-approved treatments have proven inadequate. We performed a comprehensive search of three databases (PubMed, Web of Science and Embase) for articles dating from 1947 to the present. Mindful that FDA-approved and WHO-recommended analgesic medications often prove inadequate for individual patients in extremis with palliative, hospice or cancer pain, we used broad, structured inclusion criteria to retrieve articles. We retrieved 12,100 articles; after screening, we had 39 reports addressing 19 different topical agents out of the are t
