[PMID: 37957079 PMCID: PMC11103102 DOI: 10.1016/j.bja.2023.10.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Revised: 10/02/2023] [Accepted: 10/06/2023] [Indexed: 11/15/2023] Open
Abstract
The use of peripheral regional anaesthesia continues to increase, yet the evidence supporting its use and impact on relevant outcomes often lacks scientific rigour, especially when considering the use of specific blocks for a particular surgical indication. In this narrative review, we consider the relevant literature in a 10-yr period from 2013. We performed a literature search (MEDLINE and EMBASE) for articles reporting randomised controlled trials and other comparative trials of peripheral regional anaesthetic blocks vs systemic analgesia in adult patients undergoing surgery. We evaluated measures of effective treatment and complications. A total of 128 studies met our inclusion criteria. There remains variability in the technical conduct of blocks and the outcomes used to evaluate them. There is a considerable body of evidence to support the use of interscalene blocks for shoulder surgery. Saphenous nerve (motor-sparing) blocks provide satisfactory analgesia after knee surgery and are preferred to femoral nerve blocks which are associated with falls when patients are mobilised early as part of enhanced recovery programmes. There are additional surgical indications where the efficacy of cervical plexus, intercostal nerve, and ilioinguinal/iliohypogastric nerve blocks have been demonstrated. In the past 10 yr, there has been a consolidation of the evidence indicating benefit of peripheral nerve blocks for specific indications. There remains great scope for rigorous, multicentre, randomised controlled trials of many peripheral nerve blocks. These would benefit from an agreed set of patient-centred outcomes.

Abstract
INTRODUCTION Total knee arthroplasty (TKA) is commonly performed in patients with end-stage osteoarthritis or rheumatoid arthritis of the knee to reduce joint pain, increase mobility, and improve quality of life. However, TKA is associated with moderate to severe postoperative pain, which remains a significant clinical challenge. Surgeon-administered PAI and anesthesiologist-administered iPACK have proven viable alternatives to conventional peripheral nerve blocks. This review aims to discuss which IPACK block or periarticular injection, combined or not with different peripheral nerve blocks, has better effects on postoperative rehabilitation, patient satisfaction, and overall outcome. MATERIAL AND METHODS The literature review was performed on standards of care, current therapeutic options, a pain management protocol, and innovative treatment options for patients undergoing total knee arthroplasty. The literature was reviewed through four electronic databases: PubMed, Cochrane Library, Google Scholar, and Embase. RESULTS The initial search yielded 694 articles. Fifty relevant articles were selected based on relevance, recentness, search quality, and citations. Six studies compared PAI to peripheral nerve block (PNB), and eight studies checked the effectiveness of adding PNB to PAI. Three studies compared iPACK to PNB, and ten reviewed the point of adding PNB to iPACK. CONCLUSIONS The literature review indicates that the best analgesic effect is obtained by combining PAI or iPACK with a peripheral nerve block, particularly with ACB, due to its analgesic, motor-sparing effect, and satisfactory analgesia.

Abstract
BACKGROUND The analgesic effectiveness of contemporary motor-sparing nerve blocks used in combination for analgesia in total knee arthroplasty is unclear. This network meta-analysis was conducted to evaluate the analgesic effectiveness of adding single-injection or continuous adductor canal block (ACB) with or without infiltration of the interspace between the popliteal artery and the capsule of the posterior knee (iPACK) to intraoperative local infiltration analgesia (LIA), compared to LIA alone, after total knee arthroplasty. METHODS Randomized trials examining the addition of single-injection or continuous ACB with or without single-injection block at the iPACK to LIA for total knee arthroplasty were considered. The two primary outcomes were area-under-the-curve pain scores over 24 to 48 h and postoperative function at greater than 24 h. Secondary outcomes included rest pain scores at 0, 6, 12, and 24 h; opioid consumption (from 0 to 24 h and from 25 to 48 h); and incidence of nausea/vomiting. Network meta-analysis was conducted using a frequentist approach. RESULTS A total of 27 studies (2,317 patients) investigating the addition of (1) single-injection ACB, (2) continuous ACB, (3) single-injection ACB and single-injection block at the iPACK, and (4) continuous ACB and single-injection block at the iPACK to LIA, as compared to LIA alone, were included. For area-under-the-curve 24- to 48-h pain, the addition of continuous ACB with single-injection block at the iPACK displayed the highest P-score probability (89%) of being most effective for pain control. The addition of continuous ACB without single-injection block at the iPACK displayed the highest P-score probability (87%) of being most effective for postoperative function. CONCLUSIONS The results suggest that continuous ACB, but not single-injection ACB and/or single-injection block at the iPACK, provides statistically superior analgesia when added to LIA for total knee arthroplasty compared to LIA alone. However, the magnitude of these additional analgesic benefits is clinically questionable. EDITOR’S PERSPECTIVE

Arthroplast Today 2023; 22:101155. [PMID: 37663072 PMCID: PMC10472143 DOI: 10.1016/j.artd.2023.101155] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Revised: 03/22/2023] [Accepted: 05/08/2023] [Indexed: 09/05/2023] Open
Abstract
Background Patients undergoing revision total knee arthroplasty (rTKA) have historically received high doses of opioids during the perioperative period. As awareness of opioid use has heightened, opioid administration has continuously decreased. This study aimed to evaluate if peripheral nerve catheter (PNC) use in rTKA reduces opiate consumption while maintaining similar pain control and postoperative function levels. Methods A retrospective review of 354 patients who underwent rTKA between July 2019 and January 2022 was conducted. Fifty total patients who received an adductor canal PNC were propensity-matched 1:1 to a control group of 50 patients that did not receive a PNC. To assess the primary outcome of opiate consumption, nursing documented opiate administration events were converted into morphine milligram equivalents per 24-hour interval. Postoperative pain and functional status were assessed using the verbal rating scale for pain and the Activity Measure for Post-Acute Care scores, respectively. Results Compared to the control group, the PNC group demonstrated significantly lower overall inpatient opiate consumption (98.68 ± 117.03 vs 176.69 ± 203.47 morphine milligram equivalents; 44.15% decrease, P = .021) and lower verbal rating scale pain scores at 60 to 72 hours postoperatively (4.85 ± 1.24 vs 5.83 ± 1.35; 16.81% decrease, P = .038). There was no significant difference in Activity Measure for Post-Acute Care scores postoperatively (raw score: 19.41 ± 3.61 vs 19.46 ± 3.18; 0.26% decrease, P = .952). Finally, the PNC cohort was significantly less likely to be readmitted within 90 days after surgery (0.0% vs 12.0%; P = .012). Conclusions In rTKA patients, PNC can significantly reduce inpatient opioid consumption while maintaining a comparable functional recovery and superior pain control.

Motor-Sparing Effect of Adductor Canal Block for Knee Analgesia: An Updated Review and a Subgroup Analysis of Randomized Controlled Trials Based on a Corrected Classification System. Healthcare (Basel) 2023; 11:healthcare11020210. [PMID: 36673579 PMCID: PMC9859112 DOI: 10.3390/healthcare11020210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 12/28/2022] [Accepted: 12/31/2022] [Indexed: 01/12/2023] Open
Abstract
OBJECTIVE Discrepancies in the definition of adductor canal block (ACB) lead to inconsistent results. To investigate the actual analgesic and motor-sparing effects of ACB by anatomically defining femoral triangle block (FTB), proximal ACB (p-ACB), and distal ACB (d-ACB), we re-classified the previously claimed ACB approaches according to the ultrasound findings or descriptions in the corresponding published articles. A meta-analysis with subsequent subgroup analyses based on these corrected results was performed to examine the true impact of ACB on its analgesic effect and motor function (quadriceps muscle strength or mobilization ability). An optimal ACB technique was also suggested based on an updated review of evidence and ultrasound anatomy. MATERIALS AND METHODS We systematically searched studies describing the use of ACB for knee surgery. Cochrane Library, PubMed, Web of Science, and Embase were searched with the exclusion of non-English articles from inception to 28 February 2022. The motor-sparing and analgesic aspects in true ACB were evaluated using meta-analyses with subsequent subgroup analyses according to the corrected classification system. RESULTS The meta-analysis includes 19 randomized controlled trials. Compared with the femoral nerve block group, the quadriceps muscle strength (standardized mean difference (SMD) = 0.33, 95%-CI [0.01; 0.65]) and mobilization ability (SMD = -22.44, 95%-CI [-35.37; -9.51]) are more preserved in the mixed ACB group at 24 h after knee surgery. Compared with the true ACB group, the FTB group (SMD = 5.59, 95%-CI [3.44; 8.46]) has a significantly decreased mobilization ability at 24 h after knee surgery. CONCLUSION By using the corrected classification system, we proved the motor-sparing effect of true ACB compared to FTB. According to the updated ultrasound anatomy, we suggested proximal ACB to be the analgesic technique of choice for knee surgery. Although a single-shot ACB is limited in duration, it remains the candidate of the analgesic standard for knee surgery on postoperative day 1 or 2 because it induces analgesia with less motor involvement in the era of multimodal analgesia. Furthermore, data from the corrected classification system may provide the basis for future research.

Abstract
Objective To summarize the research progress of the analgesic effect of adductor canal block (ACB) applied to knee arthroplasty, in order to find the ACB mode that can obtain better effectiveness. Methods The research progress of the analgesic effect of ACB after knee arthroplasty was reviewed by widely consulting the related literature on ACB at home and abroad in recent years. Results In recent years, multimodal analgesia has become the mainstay of postoperative pain management after knee arthroplasty. Among these, ACB replaces the once "gold standard" femoral nerve block (FNB) by offering comparable and effective analgesia with better preservation of quadriceps function. It is generally safe and efficient to use 0.2% ropivacaine ACB with initial loading doses of 15-30 mL and continual loading doses of less than 8 mL/hour to give analgesia comparable to FNB with minimal impact on lower extremity muscular strength. However, the risk of patient falls must still be taken into consideration by medical staff. Adjuvants like dexmedetomidine and dexamethasone used in ACB can increase the analgesic duration and postoperative analgesic impact. As a perineural adjunct for ACB, 1 µg/kg dexmedetomidine may strike a balance between safety and analgesic efficacy. Conclusion ACB is a safe and effective analgesia method after knee arthroplasty. The adductor canal anatomy, the optimum blocking strategy and blocking site of ACB are all hotly debated and still require additional study due to the significant variety of the nerve structures in adductor canal.

Abstract
Multimodal pain management for total knee arthroplasty (TKA) is essential to enhance functional recovery. Regional anesthesia became a vital component to decrease pain after TKA. Several studies compared femoral versus adductor canal blocks, including evaluating medications that can prolong adductor canal blocks. Liposomal bupivacaine (LB) and continuous local infusion (OnQ) both extend local anesthetic delivery beyond 24 hours. This superiority study compared the use of OnQ versus LB in adductor canal blocks. A retrospective study was conducted between two cohorts of consecutive patients who received adductor canal blocks with either LB or a continuous ropivacaine infusion catheter. Morphine equivalent dose (MED), pain scores, and length of stay (LOS) were compared between the two groups by using the analysis of covariance test. There were 106 patients in the OnQ group and 146 in the LB group. The OnQ group consumed significantly fewer opioids compared with the LB group in the recovery room (5.7 MED vs. 11.7 MED, p = 0.002) and over the entire hospitalization (the recovery room plus on the floor; 33.3 MED vs. 42.8 MED, p = 0.009). Opioid use between the OnQ and LB group did not reach statistical significance (p = 0.21). The average pain scores at rest and with activity were similar in both groups (p = 0.894, p = 0.882). The LOS between the OnQ and LB groups was not statistically significant (1.2 vs. 1.3, p = 0.462). OnQ and LB were equally effective in decreasing opioid consumption on the floor over the averaged 1.3 days of hospitalization; however, the OnQ group significantly reduced opioid use in the recovery room. There was no difference in pain scores or LOS between the two groups. OnQ comparatively prolonged infusion of local anesthetic is a potential edge over LB. This advantage may offset the inconvenience of catheter management and infrequent catheter complications.

Abstract
BACKGROUND ACB is given as single injection or as continuous block or combined with IPACK block (interspace between the popliteal artery and the posterior capsule of knee) to reduce postoperative knee pain after total knee arthroplasty. The aim of this study is to evaluate the technique of ACB that is superior in controlling postoperative pain, decrease opioid consumption and facilitate ambulation in the immediate postoperative period. METHODS A total of 171 patients were analyzed from a group of 180 patients who were randomized into three groups: (1) ACB alone, (2) continuous ACB infusion via catheter (CACB) and (3) ACB combined with IPACK. The primary outcome was pain at rest and after ambulation measured by VAS scale every 8 h till 48 h after surgery. The secondary outcome measures were opioid consumption in morphine equivalents, ambulation distance measured in feet on postoperative day 2, timed up and go test, 30 s chair stand test, sitting active extension lag test and maximal knee flexion at discharge. RESULTS VAS score at rest and after ambulation, opioid consumption was significantly lower (p < 0.05%) in CACB group compared to other study groups. Similarly, patients in CACB showed significantly (p < 0.05%) better results in the secondary outcome measures. There were no significant differences in the outcomes between ACB and ACB combined with IPACK. CONCLUSION CACB allows better pain control and less opioid consumption in the immediate postoperative period after TKA compared to ACB alone or ACB with IPACK resulting in better ambulation and rehabilitation.

Abstract
Context: Good quality analgesia posttotal knee arthroplasty (TKA) contributes majorly to early mobilization and shorter hospital stay. Aim: To compare adductor canal block (ACB) versus local infiltration analgesia (LIA) for postoperative pain relief in patients undergoing TKA. Settings and Design: This prospective, single-blind, randomized controlled trial was undertaken at a tertiary care university hospital. Materials and Methods: Sixty patients of American Society of Anesthesiologists physical status Classes I, II, and III, who received spinal anesthesia for TKA were randomly allocated to two groups. Group A patients had LIA of the knee joint using a mixture of 50 mL of 0.25% bupivacaine, 10 mg morphine (1 mL) and 99 mL of normal saline. Group B patients received ACB using 25 mL of 0.5% bupivacaine under ultrasound guidance. All patients received multimodal analgesia comprising of paracetamol, diclofenac, and patient controlled analgesia with morphine in the first 24 h' postoperative period. The primary outcome measures were first 24 h' morphine consumption and pain scores at 4, 6, 8, 12, and 24 h. The secondary outcome measures were nausea/vomiting, sedation, and patient satisfaction scores. Statistical Analysis: Statistical analysis was performed using the Student's t-test, Mann–Whitney test, and Chi-square test. Results: The 24 h morphine consumption was 11.97 ± 7.97 and 10.83 ± 6.41 mg in the LIA group and ACB group, respectively (P = 0.54). No significant differences were noted either in the pain scores at rest and flexion or secondary outcome measures between both groups in the first 24 h. Conclusion: Single-shot ACB is equally effective as LIA as postoperative analgesia for TKA.

Abstract
INTRODUCTION The Serious Harm and Morbidity "SHAM" grading system has previously been proposed to categorize the risks associated with the use of invasive placebos in peripheral nerve block research. SHAM grades range from 0 (no potential complications, eg, using standard analgesia techniques as a comparator) through to 4 (risk of major complications, eg, performing a sub-Tenon's block and injecting normal saline). A study in 2011 found that 52% of studies of peripheral nerve blocks had SHAM grades of 3 or more. METHODS We repeated the original study by allocating SHAM grades to randomized controlled studies of peripheral nerve blocks published in English over a 22-month period. Documentation was made of the number of study participants, age, number of controls, body region, adverse events due to invasive placebos and any discussion regarding the ethics of using invasive placebos. We compared the proportion of studies with SHAM grades of 3 or more with the original study. RESULTS In this current study, 114 studies fulfilled the inclusion criteria, 5 pediatric and 109 adult. The SHAM grade was ≥3 in 38 studies (33.3%), with 1494 patients in these control groups collectively. Several studies discussed their reasons for choosing a non-invasive placebo. No pediatric studies had a SHAM grade of ≥3. CONCLUSIONS The use of invasive placebos that may be associated with serious risks in peripheral nerve block research has decreased in contemporary peripheral nerve block research.

Abstract
STUDY OBJECTIVE There is no established analgesic method for postoperative total knee arthroplasty. We comprehensively compared the analgesic methods for postoperative total knee arthroplasty. DESIGN A network meta-analysis of randomised controlled trials was used to compare 18 interventions, which were ranked by six outcome indices, to select the best modality. SETTING Postoperative recovery room and inpatient ward. PATIENTS 98 randomised controlled trials involving 7452 patients (ASA I-III) were included in the final analysis. INTERVENTIONS Studies that included the use of at least one of the following 12 nerve block(fascia iliaca compartment block (FIB), FNB, cFNB, single femoral nerve block (sFNB), adductor canal block (ACB), sciatic nerve block (SNB), obturator nerve block (ONB), continuous posterior lumbar plexus block (PSOAS), FNB + SNB, ACB + LIA, FNB + LIA, PCA + FNB). MEASUREMENTS Pain intensity was compared using Visual Analogue Scale (VAS). Also, postoperative complications, function score, hospital length of stay, morphine consumption and patient satisfaction were measured. MAIN RESULTS For visual analogue scale scores, continuous femoral nerve block (FNB) and FNB + sciatic nerve block (SNB) were the the most effective interventions. For reducing postoperative complications, fascia iliaca compartment block, FNB, SNB, and obturator nerve block showed the best results. For reducing postoperative morphine consumption, adductor canal block (ACB) + local infiltration analgesia (LIA) and FNB + SNB were preferred. For function scores (range of motion, Timed-Up-and-Go test), ACB and LIA were optimal choices. For reducing hospital length of stay and patient satisfaction, ACB + LIA and FNB + LIA were best, respectively. CONCLUSIONS Peripheral nerve block, especially FNB and ACB, is a better option than other analgesic methods, and its combination with other methods can be beneficial. Peripheral nerve block is a safe and effective postoperative analgesia method. However, our findings can only provide objective evidence. Clinicians should choose the treatment course based on the individual patient's condition and clinical situation.

Abstract
OBJECTIVE Individuals with chronic pain conditions often report movement as exacerbating pain. An increasing number of researchers and clinicians have recognized the importance of measuring and distinguishing between movement-evoked pain (MEP) and pain at rest as an outcome. This scoping review maps the literature and describes MEP measurement techniques. MATERIALS AND METHODS The scoping review utilized 6 databases to identify original studies that targeted pain or movement-related outcomes. Our search returned 7322 articles that were screened by title and abstract by 2 reviewers. The inclusion criteria focused on the measurement of MEP before, during, and after movement tasks in adults with chronic pain. Studies of children below 18 years of age or with nonhuman animals, case studies, qualitative studies, book chapters, cancer-related pain, non-English language, and abstracts with no full publish text were excluded from the study. RESULTS Results from 38 studies revealed great variation in the measurement of MEP, while almost all of the studies did not provide an explicit conceptual or operational definition for MEP. In addition, studies collectively illuminated differences in MEP compared with rest pain, movement provocation methods, and pain intensity as the primary outcome. DISCUSSION These results have clinically significant and research implications. To advance the study of MEP, we offer that consistent terminology, standardized measurement (appropriate for pain type/population), and clear methodological processes be provided in research publications. On the basis of the findings, we have put forth a preliminary definition of MEP that may benefit from the continued scholarly dialog.

Recommendations for Patients with High Return to Sports Expectations after TKA Remain Controversial. J Clin Med 2020; 10:jcm10010054. [PMID: 33375242 PMCID: PMC7796219 DOI: 10.3390/jcm10010054] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Revised: 12/18/2020] [Accepted: 12/22/2020] [Indexed: 11/17/2022] Open
Abstract
(1) Background: Improved surgical techniques and implants in total knee arthroplasty (TKA) have led to broader indications for surgical interventions of osteoarthritis of the knee. There is a growing young and active patient subgroup with high return to sports (RTS) expectations after TKA. The current lack of evidence regarding RTS capacity in this patient cohort, requires the consolidation of experts' opinions and experiences to address the special needs among these patients. The aim of this study was to assess current expert opinions in regard to preoperative patient assessment, surgical technique and decision-making and patient counseling for these patients. (2) Methods: We performed a survey among surgeons specialized in arthroplasty with a questionnaire designed to assess current recommendations, surgical techniques, and implant preferences as well as patient counseling in patients with high expectations for RTS after TKA. (3) Results: The majority of surgeons are in favor of return to low-impact sports after TKA within 3 to 6 months. Some even recommend return to high-impact sports. Despite improvement of surgical techniques and implants, we observed no clear preference for a single surgical technique or implant specification in active patients. (4) Conclusions: Current evidence for sports-associated complications after TKA is scarce. Despite a growing array of surgical techniques and implants, the available literature is still controversial with no single surgical technique or TKA design distinguishing itself clearly from others. Surgeons' recommendations are mostly based on their experience and training. Nonetheless, we observed growing faith in modern implants with some surgeons even recommending high-impact sports after TKA.

Abstract
STUDY OBJECTIVE This scoping review investigates the optimal combination of motor-sparing analgesic interventions for patients undergoing total knee replacement (TKR). DESIGN Scoping review. INTERVENTION MEDLINE, EMBASE and CINAHL databases were searched (inception-last week of May 2020). Only trials including motor-sparing interventions were included. Randomized controlled trials lacking prospective registration and blinded assessment were excluded. MAIN RESULTS The cumulative evidence suggests that femoral triangle blocks outperform placebo and periarticular infiltration. When combined with the latter, femoral triangle blocks are associated with improved pain control, higher patient satisfaction and decreased opioid consumption. Continuous femoral triangle blocks provide superior postoperative analgesia compared with their single-injection counterparts. However, these benefits seem less pronounced when perineural adjuvants are used. Combined femoral triangle-obturator blocks result in improved analgesia and swifter discharge compared with femoral triangle blocks alone. CONCLUSIONS The optimal analgesic strategy for TKR may include a combination of different analgesic modalities (periarticular infiltration, femoral triangle blocks, obturator nerve block). Future trials are required to investigate the incremental benefits provided by local anesthetic infiltration between the popliteal artery and the capsule of the knee (IPACK), popliteal plexus block and genicular nerve block.
