Background
The efficacy of intravenous (IV) acetaminophen compared with its oral formulation for postoperative analgesia is unknown. We hypothesized that the addition of acetaminophen to a multimodal analgesia regimen would provide improved pain management in patients after total knee arthroplasty (TKA) and that the effect of acetaminophen would be variable based on the route of delivery.Methods
The study was a single-center, randomized, double-blinded, placebo-controlled clinical trial on the efficacy of IV vs oral acetaminophen in patients undergoing unilateral TKA. One hundred seventy-four subjects were randomized to one of the 3 groups: IV acetaminophen group (IV group, n = 57) received 1 g IV acetaminophen and oral placebo before postanesthesia care unit (PACU) admission; oral acetaminophen group (PO group, n = 58) received 1 g oral acetaminophen and volume-matched IV normal saline; placebo group (Placebo group, n = 59) received oral placebo and volume-matched IV normal saline. Pain scores were obtained every 15 minutes during PACU stay. Average pain scores, maximum pain score, and pain scores before physical therapy were compared among the 3 groups. Secondary outcomes included total opiate consumption, time to PACU discharge, time to rescue analgesia, and time to breakthrough pain.Results
The average PACU pain score was similar in the IV group (0.56 ± 0.99 [mean ± standard deviation]) compared with the PO group (0.67 ± 1.20; P = .84) and Placebo group (0.58 ± 0.99; P = .71). Total opiate consumption at 6 hours (0.47 mg hydromorphone equivalents ± 0.56 vs 0.54 ± 0.53 vs 0.54 ± 0.61; P = .69) and at 24 hours (1.25 ± 1.30 vs 1.49 ± 1.34 vs 1.36 ± 1.31; P = .46) were also similar between the IV, PO, and Placebo groups. No significant differences were found between all groups for any other outcome.Conclusion
Neither IV nor oral acetaminophen provides additional analgesia in the immediate postoperative period when administered as an adjunct to multimodal analgesia in patients undergoing TKA in the setting of a spinal anesthetic. 相似文献2.

Background
Although multimodal pain management including periarticular multidrug injection can provide excellent pain relief in the early postoperative period after total knee arthroplasty (TKA), rebounding pain remains an important challenge. A randomized, double-blind, placebo-controlled trial was performed to investigate the efficacy of adding intravenous acetaminophen to multimodal pain management for TKA.Methods
We enrolled 67 patients scheduled for unilateral TKA. Patients were randomly assigned to receive either 1000 mg of intravenous acetaminophen at 6-hour intervals or normal saline at the same intervals. All patients were treated with intraoperative periarticular multidrug injection and intravenous and oral nonsteroidal anti-inflammatory drugs. The primary outcome was the postoperative 100-mm visual analog pain scale at the time of administration of study drugs.Results
In the intention-to-treat analysis, the pain score was significantly better in the intravenous acetaminophen group than the placebo group at 17:00 one day after TKA (15.3 ± 17.0 mm vs 26.8 ± 19.0 mm; P = .013). There were no significant differences in terms of the rate of complications between groups.Conclusion
Even in the setting of multimodal pain management including periarticular multidrug injection, intravenous acetaminophen provided better pain relief for patients undergoing unilateral TKA. 相似文献3.

Background
Periarticular injection of liposomal bupivacaine has been adopted as part of multimodal pain management after total knee arthroplasty (TKA).Methods
In this prospective, randomized clinical trial, we enrolled 162 patients undergoing primary TKA in a single institution between January 2014 and May 2015. Eighty-seven patients were randomized to liposomal bupivacaine (experimental group), and 75 patients were randomized to free bupivacaine (control group). All patients received spinal anesthesia and otherwise identical surgical approaches, pain management, and rehabilitation protocols. Outcomes evaluated include the patient-reported visual analog pain scores, narcotic consumption, and narcotic-related side effects (Brief Pain Inventory) within 96 hours after surgery as well as functional outcomes using the Knee Society Score and the Short-Form 12 measured preoperatively and at 4-6 weeks after surgery.Results
There were no statistically significant differences between the groups in terms of postoperative daily pain scores, narcotic consumption (by-day and overall), or narcotic-related side effects. There were no statistically significant differences between the groups in terms of surgical (P = .76) and medical complications or length of hospital stay (P = .35). There were no statistically significant differences in satisfaction between the groups (P = .56) or between the groups in postoperative Knee Society Score (P = .53) and the Short-Form 12 at 4-6 weeks (P = .82, P = .66).Conclusion
As part of multimodal pain management protocol, periarticular injection of liposomal bupivacaine compared with bupivacaine HCl did not result in any clinically or statistically significant improvement of the measured outcomes following TKA. 相似文献4.

Background
The efficacy and costs of indwelling interscalene catheter (ISC) and liposomal bupivacaine (LBC), with and without adjunctive medications, in patients with primary shoulder arthroplasty are a source of current debate.Methods
In 214 arthroplasties, 156 patients had ISC and 58 had LBC injections that were mixed with morphine, ketorolac, and 0.5% bupivacaine with epinephrine. Charts were reviewed for visual analog scale pain scores, oral morphine equivalent (OME) usage, major complications, and costs.Results
Visual analog scale scores were not significantly different at 24 hours or at 2, 6, and 12 weeks. Average OME consumption at 24 hours was significantly more with LBC, but was not significantly different at 12 weeks. Relative risk of a major complication was nearly 4 times higher with ISC than with LBC. The average cost for the LBC mixture was $289.04, and for ISC, including equipment and anesthesia fees, was $1559.42.Conclusion
The intraoperative LBC mixture provided equivalent pain relief with significantly fewer major complications and at markedly lower cost than ISC. LBC required almost twice as much OME to attain the same level of pain relief at 24 hours, but there was no significant difference in the cumulative amount of outpatient narcotic use. 相似文献5.

Background
The coexistence of degenerative hip disease and spinal pathology is not uncommon with the number of surgical treatments performed for each condition increasing annually. The limited research available suggests spinal pathology portends less pain relief and worse outcomes after total hip arthroplasty (THA). We hypothesize that primary THA patients with preexisting lumbar spinal fusions (LSF) experience worse early postoperative outcomes.Methods
This study is a retrospective matched cohort study. Primary THA patients at 1 institution who had undergone prior LSF (spine arthrodesis-hip arthroplasty [SAHA]) were identified and matched to controls of primary THA without LSF. Early outcomes (<90 days) were compared.Results
From 2012 to 2014, 35 SAHA patients were compared to 70 matched controls. Patients were similar in age, sex, American Society of Anesthesiologist score, body mass index, and Charlson Comorbidity Index. SAHA patients had higher rates of complications (31.4% vs 8.6%, P = .008), reoperation (14.3% vs 2.9%, P = .040), and general anesthesia (54.3% vs 5.7%, P = .0001). Bivariate analysis demonstrated SAHA to predict reoperation (odds ratio, 5.67; P = .045) and complications (odds ratio, 4.89; P = .005). With the numbers available, dislocations (0% vs 2.8%), infections (0% vs 8.6%), readmissions, postoperative walking distance, and disposition only trended to favor controls (P > .05). Comparing controls to SAHA patients with <3 or ≥3 levels fused, longer fusions had increased cumulative postoperative narcotic consumption (mean morphine equivalents, 44.3 vs 46.9 vs 169.4; P = .001).Conclusion
Patients with preexisting LSF experience worse early outcomes after primary THA including higher rates of complications and reoperation. Lower rates of neuraxial anesthesia and increased narcotic usage represent potential contributors. The complex interplay between the lumbar spine and hip warrants attention and further investigation. 相似文献6.

Background
Multimodal pain protocols have reduced opioid requirements and decreased complications after elective total hip arthroplasty (THA) and total knee arthroplasty (TKA). However, these protocols are not universally effective. The purposes of this study are to determine the risk factors associated with increased opioid requirements and the impact of preoperative narcotic use on the length of stay and inhospital complications after THA or TKA.Methods
We prospectively evaluated a consecutive series of 802 patients undergoing elective primary THA and TKA over a 9-month period. All patients were managed using a multimodal pain protocol. Data on medical comorbidities and history of preoperative narcotic use were collected and correlated with deviations from the protocol.Results
Of the 802 patients, 266 (33%) required intravenous narcotic rescue. Patients aged <75 years (odds ratio [OR], 1.85; 95% confidence interval [CI], 1.10-3.12; P = .019) and with preoperative narcotic use (OR, 2.74; 95% CI, 2.01-3.75; P < .001) were more likely to require rescue. Multivariate logistic regression analysis demonstrated that preoperative narcotic use (OR, 2.74; 95% CI, 2.01-3.75; P < .001) was the largest independent predictor of increased postoperative opioid requirements. These patients developed more inhospital complications (OR, 1.92; 95% CI, 1.34-2.76; P < .001). This was associated with an increased length of stay (OR, 1.59; 95% CI, 1.06-2.37; P = .025) and a 2.5-times risk of requiring oral narcotics at 3 months postoperatively (OR, 2.48; 95% CI, 1.61-3.82; P < .001).Conclusion
Despite the effectiveness of multimodal postoperative pain protocols, younger patients with preoperative history of narcotic use require additional opioids and are at a higher risk for complications and a greater length of stay. 相似文献7.

Background
It is increasingly apparent that the effect of obesity in arthroplasty is joint-specific. This study evaluates the effects of morbid obesity on primary total knee arthroplasty by comparing short-term outcomes between a morbidly obese (body mass index ≥40 kg/m2) and a normal weight (body mass index 18.5-<25 kg/m2) cohort at our institution between January 2003 and December 2010.Methods
One hundred seventeen morbidly obese patients were compared with 94 normal weight patients. Operative time, length of stay, complications, 30-day readmission, and readmission length were compared.Results
Morbid obesity conveyed no significant increase in 30-day readmission. Operative time was increased at 100 minutes in the morbidly obese group, compared with 90.5 minutes (P = .026).Conclusion
Morbid obesity conveyed no increased risk of length of stay or readmission in this cohort. 相似文献8.

Background
Cement fixation of total knee components remains the gold standard despite resurgence in cementless fixation with the goal of long-term durable fixation. Initial stability is paramount to achieve bony ingrowth of cementless components.Methods
Twelve cemented and cementless tibial baseplates were implanted into sawbones and tested using a physiological medial-lateral load distribution for 10,000 cycles to represent 8 weeks of in vivo function. Micromotion was measured at 5 locations around the baseplate during loading.Results
Cycling had a significant effect on the change in micromotion between maximum and minimum loads at the anterior, medial, lateral, posteromedial, and posterolateral tray edge locations. A significant effect of fixation technique was detected for the anterior (P < .001), medial (P = .002), and lateral (P = .0056) locations but not for the posteromedial (P = .36) or posterolateral (P = .82) locations. Differences in micromotion between cemented and cementless components did not exceed 150 μm at any tested location.Conclusion
The micromotion experienced by cementless tibial components in the present study may indicate a lower initial mechanical stability than the cemented group. However, this difference in initial stability may be subclinical because the differences between average cemented and cementless micromotion were <150 μm at all measured locations under the loading regime implemented. 相似文献9.
Background
The optimal administration route of tranexamic acid (TXA) in total knee arthroplasty (TKA), and the effect of TXA on hidden blood loss and total blood loss are undetermined. The purpose of this study was to compare the effectiveness of intravenous versus intra-articular application of tranexamic acid in patients undergoing knee arthroplasty.Methods
A total of 150 patients undergoing primary unilateral total knee arthroplasty were randomly distributed to 3 groups (IV, intra-articular, and control group; each 50 patients) and administrated TXA (1 g IV and 50 mL intra-articular saline, 1 g intra-articularly and 50 mL intra-articular saline, and 0 g and 50 mL intra-articular saline, respectively). The amount of total and hidden blood loss (HBL), drainage, transfusion, changes in hemoglobin levels, and complications were recorded.Results
Intra-articular use of TXA reduced more total blood loss (P = .011) and reduced more total 48 hours drainage volume than IV use of TXA (P < .001). Two patients received transfusion in IV and control group. No deep venous thrombosis or other severe complications had occurred. The HBL volume had no significant difference among the control, IV, and intra-articular groups (708.6 ± 308.2, 651.7 ± 302.9, and 625.2 ± 252.1 mL, respectively; which was 65.6%, 70.8%, and 81.1% of the total loss).Conclusion
Intra-articular administration of TXA significantly reduced total blood loss and drainage volume to a greater degree than IV injection in total knee arthroplasty without reduction of HBL. 相似文献10.

Background
Fibrin sealants are topical agents used to reduce perioperative blood loss; however, their efficacy in total hip arthroplasty (THA) remains uncertain. The purpose of this study was to determine if a fibrin sealant containing aprotinin as an antifibrinolytic agent, TISSEEL (Baxter, Deerfield, IL), reduces postoperative blood loss and transfusion during THA when compared with intravenous (IV) tranexamic acid (TXA) and control groups.Methods
Three retrospective uniform cohorts of primary THA procedures were identified, from a prospectively maintained database: 1 group who received TISSEEL, 1 group who received 1 g IV TXA, and 1 group who received neither (control). There were 80 patients in each group. Outcome measures included the lowest measured hemoglobin during postoperative hospitalization, greatest decrease in hemoglobin from preoperative to postoperative values, and blood transfusion rates.Results
The minimum postoperative hemoglobin level was significantly lower for TISSEEL patients compared with that of IV TXA patients (P = .021) and no different when compared with that of control patients (P = .134). Patients receiving fibrin sealant had a greater hemoglobin level decrease compared with that of IV TXA (P = .029) and control (P = .036). Postoperative transfusion rates were no different for the group receiving TISSEEL compared with those of control (P = .375) and were statistically greater when compared with those of IV TXA (P = .002).Conclusion
TISSEEL fibrin sealant does not reduce postoperative blood loss or transfusions; however, IV TXA reduced postoperative transfusions compared with TISSEEL and control. Therefore, TXA is recommended to reduce perioperative blood loss, while, utilization of a fibrin sealant requires further refinements before being adopted for routine use in THA. 相似文献11.

Background
The ideal fixation for modern tibial components in total knee arthroplasty (TKA) remains controversial with uncertainty on whether cementless implants can yield equivalent outcomes to cemented fixation in early follow-up.Methods
A series of 70 consecutive cases with reverse hybrid cementless fixation were matched to 70 cemented cases from 2008 to 2015 based on implant design and patient demographics.Results
Cementless TKA demonstrated greater aseptic loosening (7 vs 0, P = .013) and revision surgery (10 vs 0, P = .001) than cemented fixation within 5 years of follow-up, but with no clinically significant differences in outcome scores.Conclusion
It remains unclear whether early aseptic loosening in cementless TKA can be reduced with enhanced adjunct fixation and what proportion of early failure justifies the potential lifelong fixation through biologic ingrowth of cementless tibial components. 相似文献12.
Background
Most patients experience moderate to severe pain after total knee arthroplasty (TKA). We hypothesized that intraoperative treatment of cut bone surfaces with local anesthetic (preimplantation immersion anesthesia, PIA) would lead to decreased postoperative pain and opioid consumption.Methods
Records of 76 patients who underwent unilateral, cemented TKA were retrospectively reviewed. For PIA patients, surgical wounds were immersed in local anesthetic solution immediately prior to component implantation. Both PIA (n = 43) and control (n = 33) groups received multimodal pain management, including intra-articular local anesthetic injections. Endpoints were opioid consumption and mean pain scores for postoperative day (POD) 0, 1, and 2. Demographic, medical, and social factors were included in multivariate analyses.Results
PIA patients reported significantly lower mean pain scores than controls on PODs 0 and 1 (both P < .005). Pain scores on POD 2 were similar. PIA patients used 45%-33% less opioids on PODs 0, 1, and 2 (all P < .005). POD 0 pain scores showed a significant interaction between PIA treatment and preoperative opioid use (P = .013). On POD 1, PIA was the only factor associated with lower mean pain scores (P < .001). No factors were significant for POD 2. PIA was the only factor associated with lower postoperative opioid consumption on PODs 0 and 2 (both P < .005). For POD 1, PIA and increasing age (both P ≤ .005) were associated with lower postoperative opioid consumption.Conclusion
PIA was associated with significant reductions in opioid use and mean pain scores after TKA. 相似文献13.

Background
Improved pain management and early mobilization protocols have increased interest in the feasibility of short stay (<24 hours) or outpatient total hip (THA) and total knee (TKA) arthroplasty. However, concerns exist regarding patient safety and readmissions. The purposes of this study were to determine the incidence of in-hospital complications following THA/TKA, to create a model to identify comorbidities associated with the risk of developing major complications >24 hours postoperatively, and to validate this model against another consecutive series of patients.Methods
We prospectively evaluated a consecutive series of 802 patients who underwent elective primary THA and TKA over a 9-month period. The mean age was 62.3 years. Demographic, surgical, and postoperative readmission data were entered into an arthroplasty database.Results
Of the 802 patients, 382 experienced a complication postoperatively. Of these, 152 (19%) required active management. Multiple logistic regression analysis identified cirrhosis (odds ratio [OR], 5.89; 95% confidence interval [CI], 1.05-33.07; P = .044), congestive heart failure (OR, 3.12; 95% CI, 1.50-6.44; P = .002), and chronic kidney disease (OR, 3.85; 95% CI, 2.21-6.71; P < .001) as risk factors for late complications. One comorbidity was associated with a 77% probability of developing a major postoperative complication. This model was validated against an independent dataset of 1012 patients.Conclusion
With improved pain management and mobilization protocols, there is increasing interest in short stay and outpatient THA and TKA. Patients with cirrhosis, congestive heart failure, or chronic kidney disease should be excluded from early discharge total joint arthroplasty protocols. 相似文献14.

Background
To investigate changes in lower extremity coronal alignment in patients with unilateral Crowe type IV developmental dysplasia of the hip who underwent total hip arthroplasty with transverse femoral shortening osteotomy.Methods
We reviewed the preoperative and 1-year postoperative full-length lower extremity radiographs of 25 patients. Femoral offset (FO), mechanical hip-knee-ankle angle, anatomical axis, mechanical axis deviation (MAD), mechanical lateral proximal femoral angle, anatomical medial proximal femoral angle, mechanical lateral distal femoral angle, anatomical lateral distal femoral angle, knee joint line congruency angle, mechanical medial proximal tibial angle, mechanical lateral distal tibial angle, ankle joint line orientation angle, tibial plafond talus angle, extremity length, and pelvic obliquity were measured on both the operative and nonoperative sides.Results
Postoperatively, there were significant changes in FO (P = .001), hip-knee-ankle angle (P = .004), MAD (P = .016), mechanical lateral proximal femoral angle (P = .001), anatomical medial proximal femoral angle (P = .012), mechanical lateral distal femoral angle (P = .043), and ankle joint line orientation angle (P = .012) on the operative side. Only MAD (P = .035) changed significantly on the nonoperative side.Conclusion
Modification of FO and reconstruction of hip joint anatomy led to neutralization of knee and ankle valgus alignment. Effects on the nonoperative side were minimal. 相似文献15.

Background
Recently, the direct superior approach (DSA) has been introduced in total hip arthroplasty (THA) with the goal of limiting soft tissue dissection. This study's purpose was to use a visual pain diagram questionnaire to determine the location and severity of pain in patients undergoing THA via a DSA vs miniposterior approach (MPA).Methods
This was a prospective, Institutional Review Board (IRB)-approved investigation from 3 centers. Patients aged 18-70 years with a diagnosis of osteoarthritis were included. Two centers used the MPA, while 1 center the DSA. The DSA uses a 9- to 12-cm incision with its distal extent at the posterosuperior greater trochanter. Dissection into the iliotibial band is avoided, and the capsule at the inferior femoral neck is preserved. All THAs in both cohorts received a cementless, titanium, proximally coated femoral stem and a hemispherical acetabular component.Results
A total of 42 DSA and 196 MPA THA patients were included. Overall, 43% of patients reported pain in at least 1 of the 8 anatomic areas assessed. There was no difference in the incidence of moderate to severe pain in any anatomic area of interest between the MPA and DSA cohorts (P = .1-.9). Specifically, the incidence of moderate to severe trochanter (17% MPA vs 17% DSA, P = .9), anterior thigh (15% MPA vs 17% DSA, P = .9), and lateral thigh pain (12% MPA vs 12% DSA, P = .9) was nearly identical in both cohorts.Conclusion
This study was unable to demonstrate a difference in the incidence of residual pain after use of a DSA or an MPA approach after THA. 相似文献16.

Background
A previous randomized clinical trial at our institution demonstrated slower recovery of 35 2-incision total hip arthroplasties (THAs) when compared with 36 mini-posterior THAs at 2 years. The primary aim of the present study was to report concise 10-year follow-up results.Methods
We retrospectively reviewed the 71 patients in the previous randomized clinical trial, comparing clinical outcomes, revisions, reoperations, and implant survivorship between the 2-incision and the mini-posterior THAs.Results
At the most recent follow-up, the mean Harris hip score was 85 in the 2-incision group and 87 in the mini-posterior group (P = .4). There were 4 revisions and 2 reoperations (16%) in the 2-incision group vs 1 revision and 3 reoperations (11%) in the mini-posterior group (P = .5). Ten-year survivorship free of aseptic revision or reoperation was 77% in the 2-incision group vs 90% in the mini-posterior group (P = .15).Conclusion
There were no improvements in early or midterm clinical outcomes with the 2-incision technique. However, there was a clinical trend toward a higher rate of aseptic revisions in the 2-incision THA group. 相似文献17.

Background
Increased operative time has been associated with increased complications after total joint arthroplasty (TJA). The purpose of the present study was to investigate the effect of operative time on short-term complications after TJA while also identifying patient and operative factors associated with prolonged operative times.Methods
The American College of Surgeons National Surgical Quality Improvement Program database was queried from 2011-2013 to identify all patients who underwent primary total hip or knee arthroplasty. Patients were stratified by operative time, and 30-day morbidity and mortality data compared using univariate and multivariable analyses.Results
We identified 99,444 patients who underwent primary TJA. The overall incidence of complications after TJA was 4.9%. Overall complications were increased in patients with operative times >120 minutes (5.9%) as compared to patients with operative times <60 minutes or 60-120 minutes (4.6% and 4.8%, respectively; P < .001). Wound complications, including surgical site infection, were also increased for procedures lasting >120 minutes. In a multivariable analysis, operative time exceeding 120 minutes remained an independent predictor of any complication and wound complication, with each 30-minute increase in operative time beyond 120 minutes further increasing risk. Patient age ≤65 years, male sex, black race, body mass index ≥30 kg/m2, and an American Society of Anesthesiologists classification of 3 or 4, predicted operative times >120 minutes.Conclusion
We found that operative time >120 minutes was associated with increased short-term morbidity and mortality after primary TJA. Younger age, male sex, black race, obesity, and increased comorbidity were risk factors for operative time exceeding 120 minutes. 相似文献18.

Background
There are various possible methods of skin closure in total hip arthroplasty (THA) through a lateral skin incision. The cost and time required for each can vary between techniques. The objective of this study was to determine whether there is a difference in patient and surgeon rating of scar outcome using a combination of subcuticular suture and skin adhesive (subcuticular MONOCRYL and DERMABOND [SMD]) vs staples for skin closure after THA.Methods
Patients undergoing THA were recruited from a university hospital. Patients were randomized to staples or SMD. Patient and Observer Scar Assessment Scale data were collected postoperatively. In addition, visual analog scale pain scores, wound drainage, length of stay, time to closure, and total cost were collected.Results
One hundred twenty-nine patients were available for final analysis. There was no significant difference in Patient and Observer Scar Assessment Scale scores at 6 weeks or 3 months (P = .71). There was no difference in visual analog scale pain scores (P = .64, P = .49). The staple group had a higher rate of discharge on postoperative days 1 and 3 (P < .001, P < .001) but had a 1.6-minute shorter time of closure (P < .001). There was no significant difference in length of stay or total cost (P = .5).Conclusion
Although there are some small initial advantages to each method of skin closure, there is little difference in scar outcome when comparing SMD and staples. 相似文献20.
