Total 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. ⋯ 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.

Randomized Controlled Trial
Functional Near-Infrared Spectroscopy to Assess Central Pain Responses in a Nonpharmacologic Treatment Trial of Osteoarthritis.
Knee osteoarthritis (OA) is a common source of pain in older adults. Although OA-induced pain can be relieved with analgesics and anti-inflammatory drugs, the current opioid epidemic is fostering the exploration of nonpharmacologic strategies for pain mitigation. Amongs these, transcranial direct current stimulation (tDCS) and mindfulness-based meditation (MBM) hold potential for pain-relief efficacy due to their neuromodulatory effects of the central nervous system, which is known to play a fundamental role in pain perception and processing. ⋯ In conclusion, fNIRS can be effectively used to investigate neural mechanisms of pain at the cortical level in association with nonpharmacological, self-administered treatments.

Chronic pain syndromes are poorly understood and challenging to treat. However, intrathecal drug delivery systems (IDDS) have been shown to have good efficacy in treating various pain subtypes and patient populations. The success of IDDS interventions is largely dependent on consideration of and adherence to varying practice patterns. ⋯ Incorporation of the principles found in this evidence-based narrative, which is comprised of the highest level of evidence supportive of various facets of IDDS practice management, is essential to optimize outcomes, treatment efficacy, and safety profiles.

Loss of efficacy (LOE) is a well-known phenomenon associated with spinal cord stimulation (SCS) and is the leading cause of explant. Although recent advances in neuromodulation have resulted in a decreased incidence of LOE, it still occurs. Intuition suggests that when LOE ensues, switching to a different SCS therapy/platform could potentially be a viable clinical option; however, there are no data presently available to validate this theory. ⋯ LOE is an unfortunate occurrence with few evidence-based solutions presently available to reverse it. Our findings suggest that implementing D-Burst stimulation may be an effective option for treating LOE, as well as potentially reducing opioid consumption, regardless of the prior SCS system.

State pain management clinic policies and county opioid prescribing: A fixed effects analysis.
The U.S. has seen an unprecedented rise in opioid-related morbidity and mortality, and states have passed numerous laws in response. Researchers have not comprehensively established the effectiveness of pain management clinic regulations to reduce opioid prescribing using national data. ⋯ Implementation of pain management clinic laws reduced county-level opioid prescribing. States should review specific components to determine which forms of law are most efficacious.
