Pain following total knee arthroplasty is a challenging task for healthcare providers. Concurrently, fast recovery and early ambulation are required to regain function and to prevent postoperative complications. Ideal postoperative analgesia provides sufficient pain relief with minimal opioid consumption and preservation of motor strength. Regional analgesia techniques are broadly used to answer these expectations. Femoral nerve blocks are performed frequently but have suggested disadvantages, such as motor weakness. The use of lumbar epidurals is questioned because of the risk of epidural hematoma. Relatively new techniques, such as local infiltration analgesia or adductor canal blocks, are increasingly discussed. The present review discusses new findings and weight between known benefits and risks of all of these techniques for total knee arthroplasty. ⋯ Femoral nerve blocks are still the gold standard for an effective analgesia approach in knee arthroplasty and should be supplemented (if needed) by oral opioids. An additional sciatic nerve blockade is still controversial and should be an individual decision. Large-scale studies are needed to reinforce the promising results of newer regional techniques, such as local infiltration analgesia and adductor canal block.

ReviewDiagnosis, mechanisms and treatment of complex regional pain syndrome.
The incidence and disease course of complex regional pain syndrome (CRPS) has been unclear until recently. This was due to inconsistent diagnostic criteria used in previous studies and a lack of large-scale prospective datasets. Multiple mechanisms of CRPS have been suggested, and recent research has begun to explain how inflammation, the immune system and the autonomic nervous system may interact with aberrant central neuroplasticity to produce the clinical picture. This review summarizes progress in these fields. ⋯ Recent findings in diverse research fields suggest novel treatment options for CRPS: from targeting autoimmunity to correcting abnormal body image. Many of the advances in our understanding of CRPS have arisen from the development of collaborative research efforts, such as the TREND group in the Netherlands.

Chronic pain is often accompanied by mood, sleep and cognitive complications affecting the patient's quality of life. This reviews aims to provide a synthesis of the recent clinical and preclinical findings concerning the chronic pain and mood disorder comorbidity. ⋯ The epidemiological studies report a high prevalence of mood disorders in patients with chronic pain, and these consequences of pain can be preclinically modeled. This comorbidity may be explained by shared morphological and functional alterations observed in both chronic pain and mood disorders. However, mechanistic studies also highlight differences in such alterations depending on the type of chronic pain. Better understanding of the genetic and environmental determinants of pain-induced mood disorders and of the various neurobiological bases of this comorbidity depending on the pain subtype could provide the clinician with important diagnosis and treatment tools. Such progress benefits from translational effort between clinical and preclinical research.

This review highlights new data and current trends of well tolerated and effective paediatric regional anesthesia. Historically, the practice of paediatric regional anesthesia was based largely on information from adult studies, but recent literature contains information on paediatric specific risks and benefits of old and new techniques as well as the impact of new ideas and technologies. ⋯ Paediatric specific data for regional anesthesia are available to help guide optimal pain management. The paediatric regional anesthesia literature lags behind literature available for adult populations and increased studies are needed for additional information for informed decision-making.

Robots in regional anesthesia are used as a tool to automate the performance of regional techniques reducing the anesthesiologist's workload and improving patient care. The purpose of this review is to show the latest findings in robotic regional anesthesia. ⋯ Robots can improve the performance and safety in regional anesthesia. In this review, we present the developments made in robotic and automated regional anesthesia, and discuss the current state of research in this field.
