Abstract
PURPOSE To assess the relative effectiveness of different regional anesthetic techniques (peripheral nerve blocks, local instillation analgesia, including intra-articular, subcutaneous, and periarticular infiltration) in patients undergoing anterior cruciate ligament reconstruction (ACLR). METHODS PubMed, Embase, Cochrane Library, and Web of Science databases were searched from their inception to December 31, 2020. The search was supplemented by manual review of relevant reference lists. Randomized controlled trials of participants after ACLR that compared regional anesthesia interventions were selected. The 2 coprimary outcomes were (1) rest pain scores and (2) cumulative oral morphine equivalent consumption on day 1 (24 hours) post-ACLR. Data were pooled using a Bayesian framework. RESULTS Of 759 records identified, 46 trials were eligible, evaluating 9 interventions in 3,171 patients. Local instillation analgesia (LIA), including intra-articular, subcutaneous, and periarticular infiltration, had significant improvement in pain relief as compared with placebo (-0.91; 95% CrI -1.45 to -0.37). Femoral nerve block (FNB) also showed significant effects in relieving pain as compared with placebo (-0.70; 95% 95% credible interval [CrI] -1.28 to -0.12). Compared with placebo, a significant reduction in opioid consumption was found in LIA (mean difference -13.29 mg; 95% CrI -21.77 to -4.91) and FNB (mean difference -13.97 mg; 95% CrI -24.71 to -3.04). Femoral and sciatic nerve block showed the greatest ranking for pain relief and opioid consumption without significant evidence (P > .05) to support superiority in comparison with placebo, respectively. CONCLUSIONS Our meta-analysis shows that FNB and LIA can significantly diminish postoperative pain and reduce opioid consumption following ACLR compared with placebo in the setting of regional anesthesia, and femoral and sciatic nerve block may be the number 1 top-ranked analgesic technique despite high uncertainty.

Abstract
Anterior cruciate ligament reconstruction can cause moderate to severe acute postoperative pain. Despite advances in our understanding of knee innervation, consensus regarding the most effective regional anaesthesia techniques for this surgical population is lacking. This network meta-analysis compared effectiveness of regional anaesthesia techniques used to provide analgesia for anterior cruciate ligament reconstruction. Randomised trials examining regional anaesthesia techniques for analgesia following anterior cruciate ligament reconstruction were sought. The primary outcome was opioid consumption during the first 24 h postoperatively. Secondary outcomes were: rest pain at 0, 6, 12 and 24 h; area under the curve of pain over 24 h; and opioid-related adverse effects and functional recovery. Network meta-analysis was conducted using a frequentist approach. A total of 57 trials (4069 patients) investigating femoral nerve block, sciatic nerve block, adductor canal block, local anaesthetic infiltration, graft-donor site infiltration and systemic analgesia alone (control) were included. For opioid consumption, all regional anaesthesia techniques were superior to systemic analgesia alone, but differences between regional techniques were not significant. Single-injection femoral nerve block combined with sciatic nerve block had the highest p value probability for reducing postoperative opioid consumption and area under the curve for pain severity over 24 h (78% and 90%, respectively). Continuous femoral nerve block had the highest probability (87%) of reducing opioid-related adverse effects, while local infiltration analgesia had the highest probability (88%) of optimising functional recovery. In contrast, systemic analgesia, local infiltration analgesia and adductor canal block were each poor performers across all analgesic outcomes. Regional anaesthesia techniques that target both the femoral and sciatic nerve distributions, namely a combination of single-injection nerve blocks, provide the most consistent analgesic benefits for anterior cruciate ligament reconstruction compared with all other techniques but will most likely impair postoperative function. Importantly, adductor canal block, local infiltration analgesia and systemic analgesia alone each perform poorly for acute pain management following anterior cruciate ligament reconstruction.

Abstract
BACKGROUND Peripheral nerve blocks (PNBs) are vital in the administration of surgical analgesia and have grown in popularity for use in lower extremity arthroscopic procedures because of their capacity to safely and effectively control pain. The number and specificity of PNBs, however, have made choosing the best option for a procedure nebulous for orthopaedic surgeons. PURPOSE To present a narrative literature review of the PNBs available for arthroscopic hip and knee procedures that is adapted to an audience of orthopaedic surgeons. STUDY DESIGN Narrative literature review. METHODS A combination of the names of various lower extremity PNBs AND "hip arthroscopy" OR "knee arthroscopy" was used to search the English medical literature including PubMed, Cochrane Library, ScienceDirect, Embase, and Scopus. Placement technique, specificity of blockade, efficacy, and complications were assessed. Searches were performed through May 2, 2021. RESULTS A total of 157 studies were included in this review of lower extremity PNBs. Femoral nerve, lumbar plexus, sciatic nerve, and fascia iliaca compartment blocks were most commonly used in arthroscopic hip surgery, while femoral nerve, 3-in-1, and adductor canal blocks were preferred for arthroscopic knee surgery. Each block demonstrated a significant benefit (P > .05) in ≥1 of the following outcomes: intraoperative morphine, pain scores, nausea, and/or opioid consumption. Combination blocks including the lateral femoral cutaneous nerve block, obturator nerve block, quadratus lumborum block, and L1 and L2 paravertebral block have also been described. Complication rates ranged from 0% to 4.8% in those administered with ultrasound guidance. The most commonly reported complications included muscular weakness, postoperative falls, neuropathy, intravascular and intraneural injections, and hematomas. CONCLUSION When administered properly, PNBs were a safe and effective adjuvant method of pain control with a significant potential to limit postoperative narcotic use. While blockade choice varies by surgeon preference and procedure, all PNBs should be administered with ultrasound guidance, and vigilant protocols for the risk of postoperative falls should be exercised in patients who receive them.

Abstract
INTRODUCTION Successful outpatient anterior cruciate ligament (ACL) reconstruction hinges on effective analgesia. Routinely, oral narcotic agents have been the preferred analgesic postoperatively in orthopaedic surgery. However, these agents have several known adverse effects and are associated with a potential for abuse. This study evaluates the efficacy of ketorolac, a nonsteroidal anti-inflammatory drug with analgesic properties, as an adjuvant agent for postoperative pain control after ACL reconstruction. METHODS Adult patients undergoing primary ACL reconstruction were prospectively enrolled. Exclusion criteria involved patients with a history of bleeding diathesis, renal dysfunction, chronic analgesia use, or alcohol abuse. Eligible patients were randomized into one of two groups. The control group received a standard-of-care pain protocol involving oxycodone-acetaminophen 5 to 325 on discharge. The ketorolac group additionally received intravenous ketorolac postoperatively and 3 days of oral ketorolac on discharge. Pain levels and total narcotic utilization were recorded three times per day for the first 5 days after surgery. Pain and functional outcomes were obtained at 2 and 6 weeks postoperatively. RESULTS The final analysis included 48 patients; the mean age of the cohort was 32 ± 11.6 years, and 60.4% of patients were female. No differences were observed in preoperative demographics, comorbidities, and preoperative functional scores between the two groups. Over the first 5 days after surgery, patients in the ketorolac group consumed a mean of 45.4% fewer narcotic pills than the control group (P < 0.001). In addition, mean postoperative pain scores were 22.36 points lower for patients in the ketorolac group (P < 0.001). There was no difference in functional outcome scores at up to 6 weeks postoperatively or adverse events between the two groups with no reported cases of gastrointestinal bleeding. DISCUSSION The use of adjunctive intravenous and short-term oral ketorolac substantially reduces narcotic utilization and pain levels after ACL reconstruction.

A quadruple peripheral nerve block outside the OR for anterior cruciate ligament reconstruction reduces the OR occupancy time. Knee Surg Sports Traumatol Arthrosc 2022:10.1007/s00167-022-07246-2. [PMID: 36469051 DOI: 10.1007/s00167-022-07246-2] [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: 07/08/2022] [Accepted: 11/22/2022] [Indexed: 12/07/2022]
Abstract
PURPOSE The use of regional anesthesia (RA) for anterior cruciate ligament (ACL) reconstruction reduces morphine consumption, the time spent in the post-anesthesia care unit (PACU) and the hospital readmission rate. However, RA failures due to delays in the induction of anesthesia and its unpredictable success rate (Cuvillon et al. Ann Fr Anesth 29:710-715, 2010; Jankowski et al. Anesth Analg 10.1213/01.ANE.0000081798.89853.E7) can lead to disorganization of the operating room (OR) schedule. The hypothesis is that performing RA outside the OR will significantly reduce the OR occupancy time relative to using general anesthesia (GA). The primary objective was to compare the OR occupancy time between RA and GA when performing ACL reconstruction. METHODS This was a retrospective, single-center study of data collected prospectively from consecutive patients operated by a single surgeon between January 2019 and December 2020. The patients undergoing ACL reconstruction were divided into two groups based on the type of anesthesia they received (GA, RA). RA consisted of a quadruple peripheral nerve block (femoral, sciatic, obturator and lateral femoral cutaneous nerves). The durations of the perioperative stages of the patient's journey in the OR suite were compared between these two groups. RESULTS The analysis involved 469 ACL reconstructions: 356 GA and 113 RA. The two groups were comparable in age, gender and ASA score (American Society of Anesthesiologists). The OR occupancy time for ACL reconstruction with RA was reduced by a mean of 13 min (70 ± 12 SD vs. 83 ± 14 SD; P < 0.0001) and the PACU time by 41 min relative to GA (P < 0.0001). The entry-incision time was reduced by an average of 8 min and the end-exit time by 3 min (P < 0.0001). The care time in the PACU was reduced from 84 ± 35 to 46 ± 26 min (P < 0.0001). However, performing anesthesia outside the OR (i.e., in a RA block room) did not reduce the turnover time (n.s). CONCLUSION Performing RA outside the OR reduced the OR occupancy time by nearly 20% relative to using GA for ACL reconstructions. LEVEL OF EVIDENCE Level IV.

Abstract
PURPOSE To assess the relative efficacy of several clinical treatments for postoperative analgesia of anterior cruciate ligament reconstruction through network meta-analysis based on multiple published randomized controlled trials. METHODS We searched PubMed, the Cochrane library, EMBASE, and Web of Science, each from inception until February 15, 2021. Outcomes including pain scores at rest (visual analog scale, numerical rating scales, and other scales, which were converted to a standardized 0-10 scale), morphine consumption, and complications were meta-analyzed. Quality of the included studies was assessed using the Cochrane risk-of-bias tool. The authors defined the best choice for postoperative analgesia as the one that had significant difference in pain scores, morphine consumption, and had no significant difference in the risk of complications compared with placebo in the initial 48 postoperative hours. RESULTS In total, 66 studies with 4,168 patients were included in this network meta-analysis. Only periarticular infiltration was significantly superior to placebo in pain scores and morphine consumption (pain at 2 hours: mean difference [MD] -0.74, 95% confidence interval [CI] -1.36 to -0.12; pain at 6 hours: MD -0.81, 95% CI -1.42 to -0.21; pain at 12 hours: MD -0.85, 95% CI -1.53 to -0.17; pain at 24 hours: MD -0.80, 95% CI -1.19 to -0.40; morphine consumption at 24 hours: MD -10.12, 95% CI -14.31 to -5.93; morphine consumption at 48 hours: MD -5.62, 95% CI -6.74 to -4.51). Periarticular infiltration did not increase the risk of complications compared with placebo (nausea and vomiting: odds ratio [OR] 0.63, 95% CI 0.34-1.16; pruritus: OR 0.74, 95% CI 0.35-1.58; urinary retention: OR 0.55, 95% CI 0.25-1.23). In addition, There was no significant difference between adductor canal block and femoral nerve block in pain scores and morphine consumption (pain at 2 hours: MD -0.01, 95% CI -1.44 to 1.42; pain at 6 hours: MD 0.29, 95% CI -0.28 to 0.86; pain at 12 hours: MD 0.36, 95% CI -0.44 to 1.16; pain at 24 hours: MD 0.26, 95% CI -0.22 to 0.75; pain at 48 hours: MD -0.36, 95% CI -0.97 to 0.24; morphine at 24 hours: MD 1.04, 95% CI -4.70 to 6.79; morphine at 48 hours: MD -0.32, 95% CI -0.70 to 0.07; postoperative nausea and vomiting: OR 1.07, 95% CI 0.55-2.09; pruritus: OR 1.36, 95% CI 0.66-2.79; urinary retention: OR 1.41, 95% CI 0.37-5.29). CONCLUSIONS Based on current evidence, most analgesic methods could result in lower pain scores and decrease morphine consumption when compared with placebo; however, differences between methods were small and inconsistent. There seemed to be no significant difference between adductor canal block and femoral nerve block in pain score, morphine consumption and complications.

Abstract
INTRODUCTION Femoral nerve block (FNB) is a routinely used regional analgesic technique for anterior cruciate ligament (ACL) reconstruction. One method to balance the analgesic effect and functional impairment of FNBs may be to control the concentration of local anesthetics utilized for the block. MATERIALS AND METHODS Retrospective chart review was performed on 390 consecutive patients who underwent ACL reconstruction between June 2014 and May 2017. Patients were divided into those who received a standard (0.5%-bupivacaine) or low (0.1-0.125%-bupivacaine) concentration single-shot FNB performed with ultrasound guidance. Maximum postoperative VAS, Post-Anaesthesia Care Unit (PACU) time prior to discharge, need for additional 'rescue' block, and intravenous postoperative narcotic requirements were recorded. RESULTS A total of 268 patients (28.4 ± 11.9 years) were included for final analysis, with 72 patients in the low-concentration FNB group and 196 patients receiving the standard concentration. There were no differences in the maximum postoperative VAS between the low (6.4 ± 2.5) and standard (5.7 ± 2.9) concentration groups (P = 0.08). Similarly, the time from PACU arrival to discharge was not different between groups (P = 0.64). A sciatic rescue block was needed in 22% of patients with standard-dose FNB compared to 30% of patients receiving the low-concentration FNB (P = 0.20). Patients with a hamstring autograft harvest were more likely to undergo a postoperative sciatic rescue block compared to a bone-patellar tendon autograft (P = 0.005), regardless of preoperative block concentration. Quadriceps activation was preserved with low-concentration blocks. CONCLUSIONS Using 1/5th to 1/4th the standard local anesthetic concentration for preoperative femoral nerve block in ACL reconstruction did not significantly differ in peri-operative outcomes, PACU time, need for rescue blockade, or additional immediate opioid requirements.

Comparing the Efficacy of Postoperative Pain Control Between Intravenous Parecoxib and Oral Diclofenac in ACL Reconstruction. Orthop J Sports Med 2021; 9:23259671211041660. [PMID: 34692879 PMCID: PMC8532231 DOI: 10.1177/23259671211041660] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Accepted: 06/08/2021] [Indexed: 11/19/2022] Open
Abstract
Background: A nonsteroidal anti-inflammatory drug such as oral diclofenac is normally used to relieve postoperative pain after anterior cruciate ligament reconstruction (ACLR), but most patients continue to have moderate-to-severe pain that disturbs their rehabilitation. Some orthopaedists prefer to use intravenous (IV) parecoxib for postoperative pain control. Purpose: To compare the efficacy of IV parecoxib and oral diclofenac for postoperative pain control in ACLR. Study Design: Cohort study; Level of evidence, 3. Methods: We retrospectively collected and analyzed postoperative pain in patients who underwent both single- and double-bundle ACLR; pain was reported on a 10-point visual analog scale (VAS; 10 = worst pain). After the operation, each patient was given either IV parecoxib twice a day or oral diclofenac 3 times a day, and all patients received paracetamol 6 times per day for 24 hours postoperatively. If the patient complained of moderate or severe pain (VAS >3) after surgery, 3 mg of morphine would be given intravenously every 3 hours and 1 mg of morphine as a rescue analgesic every 1 hour for 24 hours postoperatively. Postoperative VAS and morphine consumption were recorded every 4 hours for 24 hours. Data were analyzed using paired t test, analysis of variance, and chi-square test. Results: Overall, 161 patients were included in this study, of whom 47 received IV parecoxib and 114 received oral diclofenac. The mean VAS scores at 4 and 8 hours postoperatively were 3.5 and 3.4, respectively, in the parecoxib group, and 4.4 and 4.7, respectively, in the diclofenac group. The parecoxib group had significantly lower mean VAS than the diclofenac group at 4 hours (P = .047) and 8 hours (P = .005), and the mean cumulative morphine consumption in the parecoxib group was significantly lower than in the diclofenac group at all time points (P < .05) except 4 hours postoperatively. Conclusion: This study found that IV parecoxib was more effective than oral diclofenac in controlling postoperative pain and resulted in lower postoperative morphine consumption within the first 24 hours after ACLR.

Anterior cruciate ligament reconstructions (ACLR) are a relatively common procedure in orthopedic sports medicine with an estimated 130,000 arthroscopic operations performed annually. Most procedures are carried out on an outpatient basis, and though success rates of ACLR are as high as 95%, pain remains the most common postoperative complication delaying patient discharge, and thereby increasing the costs associated with patient care. Despite the success and relative frequency of ACLR surgery, optimal and widely accepted strategies and regimens for controlling perioperative pain are not well established. In recent years, the paradigm of pain control has shifted from exclusively utilizing opiates and opioid medications in the acute postoperative period to employing other agents and techniques including nerve blocks, intra-articular and periarticular injections of local anesthetic agents, NSAIDs, and less commonly, ketamine, tranexamic acid (TXA), sedatives, gabapentin, and corticosteroids. More often, these agents are now used in combination and in synergy with one another as part of a multimodal approach to pain management in ACLR, with the goal of reducing postoperative pain, opioid consumption, and the incidence of delayed hospital discharge. The purpose of this review is to consolidate current literature on various agents involved in the management of postoperative pain following ACLR, including the role of classically used opiate and opioid medications, as well as to describe other drugs currently utilized in practice either individually or in conjunction with other agents as part of a multimodal regimen in pain management in ACLR.

Abstract
INTRODUCTION Anterior cruciate ligament reconstruction (ACLR) ranks among the most common surgeries performed in civilian as well as military orthopedic settings. Regional anesthesia, and the femoral nerve block (FNB) in particular, has demonstrated efficacy in reducing postoperative pain and opioid use after ACLR, however concerns linger about possible impaired functional outcomes. The purpose of the current investigation was to assess International Knee Documentation Committee Subjective Knee Form (IKDC-SKF) scores at 6 to 12 months after ACLR in patients who did (FNB) and did not (NoFNB) receive a perioperative FNB. MATERIALS AND METHODS All patients undergoing unilateral ACLR in the study period were reviewed in this institutional process improvement analysis. The primary outcome was prospectively collected IKDC-SKF scores obtained at 6-12 months post-surgery. Demographic and surgical information collected as potential covariates included age, sex, body mass index (BMI), preoperative IKDC-SKF score, use of an FNB, use of another (not femoral nerve) block, American Society of Anesthesiologists (ASA) score, graft type (auto vs. allograft), concomitant meniscus or cartilage procedures, tobacco use, tourniquet time, and primary vs. revision surgery. Assuming a 1:2 ratio of patients who did not vs. did receive FNBs and a clinically meaningful difference of 7 points on the IKDC-SKF, 112 patients were required for 80% power. A regression model averaging approach examined the relationships between covariates and postoperative IKDC-SKF scores. RESULTS One hundred nineteen patients met inclusion criteria (FNB 79 and NoFNB 40). The cohorts were significantly different in several factors including BMI, ASA level, graft type, and other peripheral nerve blocks, which were controlled for through regression modeling. Regressions with model averaging examined the relationship between treatment groups and postoperative IKDC-SKF scores, along with other potential predictor variables. Estimated adjusted marginal differences in postoperative IKDC-SKF scores from the best-fitting model revealed a very small 0.66-point mean (P = .86) difference between NoFNB and FNB groups that was not statistically significant. Those who reported tobacco use had a 10.51 point (P = .008) lower mean postoperative IKDC-SKF score than those who did not report tobacco use. Every 1-point increase in the preoperative IKDC-SKF score was associated with a 0.28-point (P = .02) increase in the postsurgical IKDC-SKF score. CONCLUSIONS Active tobacco use may negatively impact short-term subjective patient-reported outcomes after ACLR, as reported by the IKDC-SKF. Lower preoperative scores are also associated with significantly lower postoperative IKDC-SKF scores while the use of a FNB was not associated with lower postoperative scores. The negative association between tobacco use and patient-reported functional outcomes after ACLR lends further support to tobacco cessation programs within the military.

Abstract
PURPOSE To systematically review randomized controlled trials (RCTs) evaluating various pain control interventions after anterior cruciate ligament reconstruction (ACLR) to determine the best-available evidence in managing postoperative pain and to optimize patient outcomes. METHODS A systematic review of the literature was performed based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. A study was included if it was an RCT evaluating an intervention to reduce postoperative pain acutely after ACLR in one of the following areas: (1) nerve blocks, (2) nerve block adjuncts, (3) intra-articular injections, (4) oral medications, (5) intravenous medications, (6) tranexamic acid, and (7) compressive stockings and cryotherapy. Quantitative and qualitative statistics were carried out, and network meta-analysis was performed where applicable. RESULTS Overall, 74 RCTs were included. Across 34 studies, nerve blocks were found to significantly reduce postoperative pain and opioid use, but there was no significant difference among the various nerve blocks in the network meta-analysis. Intra-articular injections consisting of bupivacaine and an adjunct were found to reduce reported postoperative pain scores up to 12 hours after ACLR, with significantly lower postoperative opioid use. CONCLUSIONS Nerve blocks and regional anesthesia are the mainstay treatment of postoperative pain after ACLR, with the commonly used nerve blocks being equally efficacious. Intra-articular injections consisting of bupivacaine and an adjunct were found to reduce reported postoperative pain scores up to 12 hours after ACLR, with significantly lower postoperative opioid use. There was promising evidence for the use of some oral and intravenous medications, tranexamic acid, and nerve block adjuncts, as well as cryotherapy, to control pain and reduce postoperative opioid use. LEVEL OF EVIDENCE Level II, systematic review and meta-analysis of RCTs.

Abstract
The optimal management of pain after ambulatory anterior cruciate ligament reconstruction (ACLR) is unclear. Femoral nerve block (FNB) is purported to enhance postoperative analgesia, but its effectiveness in the setting of modern multimodal analgesia is unclear. This systematic review examines the effect of adding FNB to multimodal analgesia on analgesic outcomes after ACLR, whether or not the analgesic regimen used included local instillation analgesia (LIA). We retrieved randomized controlled trials evaluating the effects of adding FNB to multimodal analgesia on analgesic outcomes after ACLR, compared to multimodal analgesia alone (control). We designated postoperative opioid consumption at 24 hours as our primary outcome. Secondary outcomes included postoperative opioid consumption at 24-48 hours, rest, and dynamic pain severity between 0 and 48 hours, time to analgesic request, postanesthesia care unit and hospital stay durations, patient satisfaction, postoperative nausea and vomiting, functional outcomes, and long-term (>1 month) quadriceps strength. Eight randomized controlled trials (716 patients) were identified. Five trials compared FNB administration to control, and another 3 compared the combination of FNB and LIA to LIA alone. Compared to control, adding FNB resulted in modest reductions in 24-hour opioid consumption in 2 of 3 trials, and improvements in rest pain at 1 hour in 1 trial and up to 24 hours in another. In contrast, the combination of FNB and LIA, compared to LIA alone, did not reduce opioid consumption in any of the trials, but it did improve pain scores at 20 minutes only in 1 trial. The effect of FNB on long-term quadriceps strength or function after ACLR was not evaluated in the reviewed trials. Contemporary evidence suggests that the benefits of adding FNB to multimodal analgesia for ACLR are modest and conflicting, but there is no incremental analgesic benefit if the multimodal analgesic regimen included LIA. Our findings do not support the routine use of FNB for analgesia in patients having ACLR.

Abstract
UNLABELLED Most patients who undergo surgical procedures experience acute postoperative pain, but evidence suggests that less than half report adequate postoperative pain relief. Many preoperative, intraoperative, and postoperative interventions and management strategies are available for reducing and managing postoperative pain. The American Pain Society, with input from the American Society of Anesthesiologists, commissioned an interdisciplinary expert panel to develop a clinical practice guideline to promote evidence-based, effective, and safer postoperative pain management in children and adults. The guideline was subsequently approved by the American Society for Regional Anesthesia. As part of the guideline development process, a systematic review was commissioned on various aspects related to various interventions and management strategies for postoperative pain. After a review of the evidence, the expert panel formulated recommendations that addressed various aspects of postoperative pain management, including preoperative education, perioperative pain management planning, use of different pharmacological and nonpharmacological modalities, organizational policies, and transition to outpatient care. The recommendations are based on the underlying premise that optimal management begins in the preoperative period with an assessment of the patient and development of a plan of care tailored to the individual and the surgical procedure involved. The panel found that evidence supports the use of multimodal regimens in many situations, although the exact components of effective multimodal care will vary depending on the patient, setting, and surgical procedure. Although these guidelines are based on a systematic review of the evidence on management of postoperative pain, the panel identified numerous research gaps. Of 32 recommendations, 4 were assessed as being supported by high-quality evidence, and 11 (in the areas of patient education and perioperative planning, patient assessment, organizational structures and policies, and transitioning to outpatient care) were made on the basis of low-quality evidence. PERSPECTIVE This guideline, on the basis of a systematic review of the evidence on postoperative pain management, provides recommendations developed by a multidisciplinary expert panel. Safe and effective postoperative pain management should be on the basis of a plan of care tailored to the individual and the surgical procedure involved, and multimodal regimens are recommended in many situations.

Abstract
BACKGROUND Effective pain management after anterior cruciate ligament (ACL) reconstruction improves patient satisfaction and function. PURPOSE To collect and evaluate the available evidence from randomized controlled trials (RCTs) on pain control after ACL reconstruction. STUDY DESIGN Systematic review. METHODS A systematic literature review was performed using PubMed, Medline, Google Scholar, UpToDate, Cochrane Reviews, CINAHL, and Scopus following PRISMA guidelines (July 2014). Only RCTs comparing a method of postoperative pain control to another method or placebo were included. RESULTS A total of 77 RCTs met inclusion criteria: 14 on regional nerve blocks, 21 on intra-articular injections, 4 on intramuscular/intravenous injections, 12 on multimodal regimens, 6 on oral medications, 10 on cryotherapy/compression, 6 on mobilization, and 5 on intraoperative techniques. Single-injection femoral nerve blocks provided superior analgesia to placebo for up to 24 hours postoperatively; however, this also resulted in a quadriceps motor deficit. Indwelling femoral catheters utilized for 2 days postoperatively provided superior analgesia to a single-injection femoral nerve block. Local anesthetic injections at the surgical wound site or intra-articularly provided equivalent analgesia to regional nerve blocks. Continuous-infusion catheters of a local anesthetic provided adequate pain relief but have been shown to cause chondrolysis. Cryotherapy improved analgesia compared to no cryotherapy in 4 trials, while in 4 trials, ice water and water at room temperature provided equivalent analgesic effects. Early weightbearing decreased pain compared to delayed weightbearing. Oral gabapentin given preoperatively and oral zolpidem given for the first week postoperatively each decreased opioid consumption as compared to placebo. Ibuprofen reduced pain compared to acetaminophen. Oral ketorolac reduced pain compared to hydrocodone-acetaminophen. CONCLUSION Regional nerve blocks and intra-articular injections are both effective forms of analgesia. Cryotherapy-compression appears to be beneficial, provided that intra-articular temperatures are sufficiently decreased. Early mobilization reduces pain symptoms. Gabapentin, zolpidem, ketorolac, and ibuprofen decrease opioid consumption. Despite the vast amount of high-quality evidence on this topic, further research is needed to determine the optimal multimodal approach that can maximize recovery while minimizing pain and opioid consumption. CLINICAL RELEVANCE These results provide the best available evidence from RCTs on pain control regimens after ACL reconstruction.

Adductor Canal Block Provides Noninferior Analgesia and Superior Quadriceps Strength Compared with Femoral Nerve Block in Anterior Cruciate Ligament Reconstruction. Anesthesiology 2016; 124:1053-64.

Abstract
BACKGROUND By targeting the distal branches of the femoral nerve in the mid-thigh, the adductor canal block (ACB) can preserve quadriceps muscle strength while providing analgesia similar to a conventional femoral nerve block (FNB) for inpatients undergoing major knee surgery. In this randomized, double-blind, noninferiority trial, the authors hypothesized that ACB provides postoperative analgesia that is at least as good as FNB while preserving quadriceps strength after outpatient anterior cruciate ligament reconstruction. METHODS A total of 100 patients were randomized to receive ACB or FNB with 20 ml ropivacaine 0.5% (with epinephrine). The authors sequentially tested the joint hypothesis that ACB is noninferior to FNB for cumulative oral morphine equivalent consumption and area under the curve for pain scores during the first 24 h postoperatively and also superior to FNB for postblock quadriceps maximal voluntary isometric contraction. RESULTS The authors analyzed 52 and 48 patients who received ACB and FNB, respectively. Compared with preset noninferiority margins, the ACB-FNB difference (95% CI) in morphine consumption and area under the curve for pain scores were -4.8 mg (-12.3 to 2.7) (P = 0.03) and -71 mm h (-148 to 6) (P < 0.00001), respectively, indicating noninferiority of ACB for both outcomes. The maximal voluntary isometric contraction for ACB and FNB at 45 min were 26.6 pound-force (24.7-28.6) and 10.6 pound-force (8.3-13.0) (P < 0.00001), respectively, indicating superiority of ACB. CONCLUSION Compared with FNB, the study findings suggest that ACB preserves quadriceps strength and provides noninferior postoperative analgesia for outpatients undergoing anterior cruciate ligament reconstruction.

Abstract
BACKGROUND Adequate pain control following anterior cruciate ligament reconstruction (ACL) often requires regional nerve block. The femoral nerve block (FNB) has been traditionally employed. Ultrasound application to regional nerve blocks allows for the use of alternatives such as the saphenous nerve block following ACL reconstruction. QUESTIONS/PURPOSES This study evaluated postoperative analgesia provided by the subsartorial saphenous nerve block (SSNB) compared to that provided by the traditional FNB for patients undergoing ACL reconstruction with patellar tendon (bone-tendon-bone (BTB)) autografts. METHODS A randomized, blinded, controlled clinical trial was conducted using 80 ASA I-III patients, ages 16-65, undergoing ACL reconstruction with BTB. The individuals assessing all outcome measures were blinded to the treatment group. Postoperatively, all patients received cryotherapy and parenteral hydromorphone to achieve numeric rating scale pain scores less than 4. At discharge, patients were given prescriptions for oral opioid analgesics and a scheduled NSAID. Patients were instructed to complete pain diaries and record oral opioid utilization. Patients were contacted on postoperative days (POD) 1 and 2 to ascertain the level of patient satisfaction with the analgesic regimen. RESULTS No differences between the two groups were found. Patient demographics and postoperative pain scores at rest were not different. In addition, there was no difference in opioid use, as measured in daily oral morphine equivalents between groups. A small but statistically significant report of higher patient satisfaction with the FNB was found on POD 1 but not on POD 2. CONCLUSION These data support our hypothesis that the SSNB provides similar and adequate postoperative analgesia when compared to the FNB, following arthroscopic ACL reconstruction with patellar tendon autograft.

Abstract
BACKGROUND Anesthetic use for arthroscopic anterior cruciate ligament (ACL) reconstruction may display variability in hospital charges and utilization in the United States. PURPOSE To evaluate practice patterns and hospital charges for anesthesia in arthroscopic ACL reconstruction. STUDY TYPE Cross-sectional study. METHODS The PearlDiver Patient Records Database, a national database of insurance billing records, was searched using the current procedural terminology (CPT) codes for arthroscopic ACL reconstruction in combination with different types of anesthesia. The search included the years between 2004 and 2009. Age, sex, number of procedures performed, geographic region, and hospital charges for each type of anesthesia were recorded and compared. Anesthetic types were categorized as general anesthesia (GA) only, GA with concomitant single femoral injection, GA with concomitant other regional anesthesia (RA), single femoral injection only, or other RA only. RESULTS Between 2004 and 2009, a total of 53,968 arthroscopic reconstructive procedures were identified. The mean per patient hospital charge for GA alone, GA in combination with single femoral injection, GA in combination with other RA, single femoral injection alone, and RA alone was $1065 (63% of cases), $1614 (29%), $1849 (4%), $630 (3%), and $612 (1%), respectively. The use of GA in combination with RA or single femoral nerve injection significantly increased during this time period (P = .004 and P < .001, respectively). CONCLUSION The mean per patient hospital charges for arthroscopic ACL reconstruction varied with the mode of anesthesia utilized, where regional anesthetic techniques alone were least expensive. RA alone was utilized infrequently, and there was a significant increase in the rate of utilization of GA in combination with any form of RA. CLINICAL RELEVANCE This study provides information on current trends and hospital charges for anesthesia in arthroscopic ACL reconstruction.

Abstract
BACKGROUND Many studies have demonstrated that either COX-2 antagonists or glucocorticoids are efficient analgesics after orthopaedic surgery. We wanted to evaluate if the combination of these two drugs was better than one drug alone when added to paracetamol, local anaesthesia, and cryo-cuff for outpatient anterior crucial ligament (ACL) surgery. METHODS In a double-blind design, 89 adult patients scheduled for day-case ACL repair in general anaesthesia were randomly assigned into three groups: The COXIB group (n = 30) received either 40 mg parecoxib iv or 120 mg etoricoxib orally 1 h before surgery. The STEROID group (n = 30) received 8 mg dexamethasone iv, and the combination group (Group COMBI, n = 29) received both. RESULTS At 24 h, Group COMBI had significantly lower visual analogue scale (0-10 cm) scores during rest (2.1 ± 1.3) (mean ± standard deviation) and movement (4.2 ± 2.5) when compared to both the COXIB group (P = 0.04) and the STEROID group (P = 0.035). The accumulated consumption of rescue opioids (5.2 ± 4,5 mg morphine) was also significantly lower at 24 h compared to the other groups (P = 0.02). Mean time to discharge from hospital was about 3 h in all groups. The pain scores in the post-anaesthetic care unit, mobilization at 24 h and 7 days, and general level of satisfaction were similar between the groups. CONCLUSION The combination of a COX-2 inhibitor and dexamethasone results in better pain relief 24 h after surgery in patients undergoing outpatient ACL surgery, compared to COX-2 inhibitor alone or dexamethasone alone. With a dedicated multimodal pain regime, most ACL patients may be discharged within 3 h.

Abstract
BACKGROUND Levobupivacaine and ropivacaine are both used for continuous femoral analgesia after anterior cruciate ligament reconstruction; however it is unknown whether both drugs are equally effective regarding pain control, preservation of mobility and patient satisfaction. METHODS AND MATERIALS In this randomized, placebo-controlled trial 84 patients undergoing anterior cruciate ligament (ACL) reconstruction with quadruple hamstring tendons were studied. For postoperative pain therapy levobupivacaine 0.125%, ropivacaine 0.2% or placebo control with NaCl 0.9% at a rate of 6 ml/h were used for 48 h using a femoral nerve catheter. All patients also received an i.v. patient-controlled analgesia (IVPCA) pump with piritramide. RESULTS Patient satisfaction was significantly higher and night rest was better in both treatment groups compared to the placebo group but there appeared to be no major differences between the two local anesthetics. Opioid consumption was significantly higher in the placebo group compared to the levobupivacaine group but not the ropivacaine group. The pain scores showed a trend towards higher scores in the placebo group throughout but the difference only reached statistical significance on postoperative day 1. No statistical significant differences in motor block were found between the three groups. CONCLUSION Postoperative analgesia for ACL reconstruction during the first 48 h using femoral block with a continuous infusion of levobupivacaine 0.125% or ropivacaine 0.2% in combination with an IVPCA is similarly effective and better than a placebo. Both studied drugs seem to be equally appropriate for this purpose.

Abstract
BACKGROUND/OBJECTIVE Our aim was to evaluate analgesia, motor block and pharmacokinetics of ropivacaine 0.2% and 0.75% in a femoral nerve block (FNB) in day case patients for anterior crucial ligament (ACL)-reconstruction compared with bupivacaine 0.25% and placebo. METHODS Following ethics committee approval and informed consent, 280 patients were randomly allocated to four groups for single-shot FNB [30 ml ropivacaine 0.2% (group RO2.0), 0.75% (RO7.5), bupivacaine 0.25% (BU2.5) and NaCl 0.9% (NaCl)]. Analgesia (pain scores, primary outcome) and motor block were assessed at 4 h (dismissal) and up to 24 h. Plasma concentration was determined up to 240 min thereafter. RESULTS Pain scores at 4 h were significantly higher for NaCl 4 (0-8) (median, range) (vs.) BU2.5 2 (0-8), RO2.0 3 (0-9) and RO7.5 2 (0-8) (NS within the LA groups). Patients of the NaCl group needed analgesics significantly more often (93%) within 4 h after surgery vs. 16% of group RO2.0, 19% of group RO7.5 and 19% of group BU2.5. Motor block was significantly increased with all local anesthetics without a significant difference within the LA groups 3 (0-5) in RO2.0, 3 (0-5) in RO7.5 and 3 (0-4) in BU2.5 vs. 0 (0-3) in group NaCl (median (range); scale from 0=full strength to 5=complete paralysis). Peak plasma concentrations differed significantly: RO7.5: 1.4 +/- 0.4 (0.73-2.6) [microg/ml, mean +/- SD (range)] after 33 +/- 14 (10-40) min, RO2.0: 0.6 +/- 0.3 (0.13-1.0) after 22+17 (10-60) and BU2.5: 0.3 +/- 0.16 (0.05-0.62) at 31 +/- 17 (10-60), respectively. CONCLUSION FNB for ACL reconstruction with ropivacaine or bupivacaine provided better post-operative analgesia than placebo without reaching toxic plasma concentrations. Significant motor block was observed after 4 h in all groups including the lowest concentration of ropivacaine but occurred even with placebo.

Abstract
PURPOSE The goal of this study was to determine whether femoral nerve blocks (FNBs) provide patients undergoing anterior cruciate ligament reconstruction greater pain relief or other benefits compared with more standard pain medication regimens. METHODS We searched PubMed, EMBASE, and the Cochrane Database using the following search terms: "ACL or anterior cruciate ligament" and "femoral nerve block or peripheral nerve block" or "regional anesthesia." Thirteen studies were found that fit the inclusion criteria of being randomized controlled trials with a Level of Evidence of I or II, comparing FNB or 3-in-1 blocks with control groups undergoing various multimodal pain regimens. RESULTS Only 5 of the 13 studies found a significant difference in pain relief with FNB compared with the control groups; however, the difference in several of the studies may not be clinically relevant. Of the 13 studies, 6 examined parameters other than pain, and only 1 study found a greater incidence of nausea and sedation in its control group. Patient satisfaction was examined in 2 studies, with both finding no difference between groups. Nine studies used a single graft type, and the two studies using multiple graft types accounted for this in their analyses. CONCLUSIONS On the basis of the available Level I and II data from randomized controlled trials, there appears to be no evidence that FNBs add additional benefit over multimodal analgesia. FNBs have not been shown to significantly affect patient pain, readiness for discharge, or outcome scores. There is a small but identifiable risk associated with performing FNBs, with potentially catastrophic effects. LEVEL OF EVIDENCE Level II, systematic review of Level I and II randomized controlled trials with minimal heterogeneity.

Abstract
BACKGROUND Femoral nerve blockade has been purported to be an effective regional anesthetic in patients undergoing various procedures to lower extremities. HYPOTHESIS Femoral nerve blockade will provide improved postoperative pain control over a local anesthetic in the knee joint alone in patients undergoing endoscopic patellar tendon anterior cruciate ligament reconstruction. STUDY DESIGN Randomized, controlled trial; Level of evidence, 1. METHODS Fifty-six adult patients undergoing an endoscopic patellar tendon anterior cruciate ligament reconstruction under general anesthesia were prospectively randomized to receive either a bupivacaine femoral nerve blockade (block) or a saline placebo injection (control). Both groups received local bupivacaine injection and intravenous ketorolac at wound closure. Outcomes included postoperative pain measured on a validated visual analog scale at postoperative intervals for 72 hours, intraoperative and postoperative narcotic consumption, admission rates, hospital charges, patient satisfaction, and complications related to the femoral nerve block. RESULTS There were 31 block patients and 25 control patients. No significant differences between groups for postoperative pain scores, intraoperative or postoperative narcotic consumption, readiness for discharge, duration of hospitalization, admission rates, hospital charges, or patient satisfaction were observed. There were no complications related to the femoral nerve block. CONCLUSION A preemptive femoral nerve blockade, although safe, does not provide significant clinical benefit in this patient population to justify its routine use.

Abstract
BACKGROUND Continuous femoral nerve blocks have been recommended for postoperative pain control after anterior cruciate ligament reconstruction. HYPOTHESIS A pain control protocol involving a continuous ropivacaine femoral nerve block will decrease pain and narcotic use in the first 24 hours after surgery compared with a postoperative pain control protocol involving an intra-articular injection of bupivacaine/morphine. STUDY DESIGN Randomized controlled clinical trial; Level of evidence, 2. METHODS Ninety subjects, aged 15 years or older, who were receiving arthroscopically assisted bone-patellar tendon-bone anterior cruciate ligament reconstruction were randomly assigned to 2 groups. The first group received a ropivacaine continuous femoral nerve block and oral hydrocodone (block group). The second group received an intra-articular bupivacaine/morphine injection and oral oxycodone (injection group). Patients in both groups could receive intramuscular injection of hydromorphone for breakthrough pain; most patients in the block group also received bolus doses of ropivacaine through the femoral catheter. Subjects rated their worst, average, and current pain levels using a visual analog scale and category-ratio scale the morning after surgery. Postoperative narcotic pain medication use was converted to morphine-equivalent doses. RESULTS Postoperative pain ratings did not differ between the treatment groups. The largest difference in pain ratings between the groups was 0.5 cm for worst pain level (P = .345). Total narcotic use did not differ significantly between groups (1.1 morphine-equivalent doses in both groups; P = .671). CONCLUSIONS Continuous femoral block with ropivacaine appeared to have no clinical advantage in the immediate postoperative period after anterior cruciate ligament reconstruction when compared with an intra-articular injection of bupivacaine/morphine. Both methods are effective for pain control after anterior cruciate ligament reconstruction.

Abstract
Daycase ACL reconstruction is commonly performed under general anaesthesia with a patella tendon graft. We report our experience with hamstring reconstruction under regional anaesthesia. Over a 14-month period, 104 daycase arthroscopic ACL reconstructions were performed by one surgeon and one anaesthetist. All operations were performed under spinal anaesthesia with a femoral nerve block. Patients were discharged with oral analgesia, brace and a cryocuff. One hundred and two patients were prospectively evaluated with a visual analogue pain score (0-10) and a patient satisfaction questionnaire. Of these 102 patients, 101 (99%) were happy to be discharged on the same day. One patient was admitted from the daycase unit, and one patient was re-admitted. Patients were very satisfied with the pain relief provided. The mean visual analogue pain score was 1.0 at discharge, 1.8 in the middle of the first night, and 2.1 on the first post-op day. Patients experienced significantly more pain the day after surgery than the evening of surgery (p=0.04). We conclude that hamstring ACL reconstruction under regional anaesthesia is well tolerated by patients as a daycase procedure.

Abstract
Peripheral nerve blocks provide intense, site-specific analgesia and are associated with a lower incidence of side effects when compared with many other modalities of postoperative analgesia. Continuous catheter techniques further prolong these benefits. These advantages can facilitate a prompt recovery and discharge and achieve significant perioperative cost savings. This is of tremendous value in a modern health care system that stresses cost-effective use of resources and a continued shift toward shorter hospital stay as well as outpatient surgery.

Abstract
Patient-controlled analgesia (PCA) has become standard procedure in the clinical treatment of pain. Its widespread use in patients with all kinds of diseases opens a variety of possible interactions between analgesics used for PCA and other drugs that might be administered concomitantly to the patient. Many of these drug interactions are of little clinical importance. However, some drug interactions have been reported to result in serious clinical problems. Drug interactions can either predominantly affect the pharmacokinetics or pharmacodynamics of the drug. Most important pharmacokinetic drug interactions occur at the level of drug metabolism or protein binding. Acceleration of methadone metabolism caused by cytochrome P450 (CYP) 3A4 induction by antiretroviral drugs or rifampicin (rifampin) has caused methadone withdrawal symptoms. Lack of morphine formation from codeine as a result of CYP2D6 inhibition by quinidine results in an almost complete loss of the analgesic effects of codeine. Alterations of methadone protein binding caused by an inhibition of alpha1-acid glycoprotein synthesis by alkylating substances are another possibility for predominantly pharmacokinetically based drug interactions during PCA. Furthermore, inhibition of P-glycoprotein by anticancer drugs could result in altered transmembrane transport of morphine, methadone or fentanyl, although this has not been shown to be of clinical relevance. Synergistic effects of systemically administered opioids with spinally or topically delivered opioids or anaesthetics have been reported frequently. The same is true for the opioid-sparing effects of coadministered non-opioid analgesics. Antidepressants, anticonvulsants or alpha2-adrenoreceptor agonists have also been shown to exert additive analgesic effects when administered together with an opioid. Inconsistent findings, however, are reported regarding the treatment of patients with opioid-induced nausea and sedation, since coadministration of antiemetics either increased or decreased the respective adverse effects or revealed additional unwanted drug effects.
