RESUMO

Pain, the main symptom of osteoarthritis (OA), can lead to functional disability in patients with knee OA. Understanding the association factors related to knee pain is important since preventing OA-induced disabilities can be achieved by modifying these pain-associated issues. Therefore, this study was aimed to investigate the association factors for OA-induced knee pain in Taiwanese patients who received total knee replacements (TKR).In this retrospective study, 357 subjects who had undergone TKR at the Taipei Municipal Wan-Fang Hospital were recruited. The distribution of pain severity among patients with knee OA was evaluated. Demographic data and clinical parameters were analyzed to determine relationships between these variables and the severity of knee OA pain.Of the 357 patients studied, 54% and 33% had moderate and severe knee pain, respectively. Furthermore, a multivariate logistic regression analysis revealed that serum creatinine (>1.5 mg/dL) and an estimated glomerular filtration rate (eGFR) (<60 mL/min/1.73 m) were significantly associated with severe knee pain in OA patients. A significant correlation between severe knee pain and serum creatinine or eGFR was demonstrated by Pearson correlations.Taken together, the renal insufficiency defined by an elevated serum creatinine or a low eGFR in OA patients who required TKR was associated with severe knee pain. These variables must be considered while treating knee OA pain, especially in those patients with severe pain.

RESUMO

The aim of this study was to determine whether the infection control rate of a modified debridement, antibiotics, and implant retention (DAIR) protocol (DAIR with antibiotic-impregnated cement beads) is comparable to that of 2-stage revision for acute periprosthetic joint infection (PJI) after total knee arthroplasty (TKA). We also aimed to determine whether this modified DAIR technique produced better clinical results than those obtained using 2-stage revision in terms of functional outcome, range of motion (ROM), and patient satisfaction at 2 years after surgery.This retrospective comparative study included patients who underwent modified DAIR (7 patients, 9 knees) or 2-stage revision (8 patients, 9 knees) for acute PJI of the knee joint. Infection control rate, functional outcome measured using Western Ontario and McMaster Universities Arthritis Index (WOMAC) score, ROM and patient satisfaction were compared between the two groups.There was no difference in infection control rates between the modified DAIR and 2-stage revision groups (78% vs 78%, respectively). In contrast, surgical outcome in the modified DAIR group was tended to be better than 2-stage revision group, but it did not reach statistical significance. Median maximal range of flexion was 103° in the modified DAIR group and it was 90° in the 2-stage group (P = .191). In addition, the median WOMAC function score was 24 in the modified DAIR group and it was 30 in the 2-stage group (P = .076). Median patient satisfaction measured using visual analogue scale was 8 in the modified DAIR group and 5 in the 2-stage group (P = .069).The infection control rates of the modified DAIR protocol and 2-stage revision protocol were similar for the treatment of acute PJI of the knee joint. However, the modified DAIR protocol could not provide substantially increased functional outcomes and patient satisfaction compared to 2-stage revision. Therefore, the modified DAIR technique should be considered to be of limited use in patients with high surgical morbidity.

RESUMO

BACKGROUND: To evaluate the safety and efficacy of dexmedetomidine in patients undergoing total knee and hip arthroplasty for postoperative pain control. METHODS: An updated systematic review and meta-analysis of randomized controlled trials (RCTs) identified in systematic searches of MEDLINE, EMBASE, Google Scholar, the Cochrane Database and the Chinese SinoMed Database. RESULTS: Fourteen RCTs with a total of 1220 patients were included. Overall, dexmedetomidine therapy was associated with significantly decreased pain scores 24 hours after surgery (WMD, -0.36; 95% CI, -0.49 to -0.22; I = 90.0%, P < .001) compared with scores in the control group after total hip arthroplasty (THA) and total knee arthroplasty (TKA). Furthermore, the rate of postoperative delirium was also markedly decreased with dexmedetomidine therapy (RR, 0.38; 95% CI, 0.24 to 0.59; I = 0.0%, P < .001). Moreover, compared with the control group, dexmedetomidine treatment was associated with a decreased risk of postoperative nausea and vomiting in patients undergoing TKA (RR, 0.34; 95% CI, 0.15 to 0.79; I = 0.0%, P = .012), and there was a similar risk of hypotension (RR, 1.03; 95% CI, 0.72 to 1.49; I = 24.4%, P = .87) regardless of whether patients underwent TKA or THA. However, the rate of bradycardia was significantly increased with dexmedetomidine treatment in those undergoing TKA (RR, 6.11; 95% CI, 2.35 to 15.91; I = 0.0%, P < .001). CONCLUSIONS: Dexmedetomidine therapy seems to be an effective treatment for pain control and postoperative delirium in patients undergoing TKA/THA. However, the incidence of bradycardia is markedly increased in patients undergoing TKA. Hence, much larger prospective clinical studies are warranted to confirm these findings.

RESUMO

INTRODUCTION: Patients with pre-existing lymphedema who undergo total knee arthroplasty (TKA) for osteoarthritis (OA) are at high risk for periprosthetic joint infection. This complication usually requires removal of the implant. This study aimed to investigate whether surgical treatment of lymphedema reduces the rate of prosthesis removal in such patients. MATERIALS AND METHODS: We retrospectively reviewed our prospective database of patient information collected between January 2009 and December 2018. A total of 348 cases of lower extremity lymphedema were reviewed, and those who underwent total knee TKA for OA of the knee were included. Patient demographics, clinical data, lymphedema surgical history, and TKA surgical history including any episodes of removal were collected and analyzed. RESULTS: There were nine of 15 lymphedema patients with knee OA who subsequently underwent TKA. The mean patient age was 70.4 ± 7.1 years. A total of 18 TKAs were performed in nine patients. The knee prosthesis removal rate was 66.7% (12/18). The prosthesis removal rate was 40% (2/5) in patients who underwent lymphedema microsurgery vs 76.9% (10/13) for those who did not (P = .03). CONCLUSIONS: Pre-existing lymphedema is associated with a high rate of knee prosthesis removal. Lymphedema microsurgery reduced the removal rate of knee prostheses. We recommend that lymphedema microsurgery be considered for patients who require TKA as a treatment for of the knee.

RESUMO

Using an age- and comorbidity-matched cohort, we compared patients who underwent unicompartmental knee arthroplasty in an ambulatory surgery center with those who underwent the procedure in a traditional hospital inpatient setting. Postoperatively, the ambulatory surgery center cohort had fewer major complications than the inpatient cohort. No ambulatory surgery center patients required acute hospital admission and none had major complications. Four major complications occurred in the inpatient cohort. There was no difference in complication rates. Our results suggest that outpatient unicompartmental knee arthroplasty in a freestanding ambulatory surgery center is a safe and reasonable alternative to the traditional inpatient hospital setting.

RESUMO

BACKGROUND: Total knee arthroplasty (TKA) is accompanied by moderate to severe postoperative pain. Multimodal analgesia, such as femoral nerve block, periarticular infiltration analgesia (PIA), and patient-controlled intravenous analgesia, have been used for postoperative analgesia. Recently, randomized controlled trials have compared the efficacy of the adductor canal block (ACB) and the PIA in patients undergoing TKA. However, there is no definite answer as to the efficacy and safety of the ACB compared with the PIA. METHOD: Randomized controlled trials about relevant studies were searched from PubMed (1996 to May 2019), Embase (1980 to May 2019), and Cochrane Library (CENTRAL, May 2019). Five studies which compared the ACB with the PIA methods were included in our meta-analysis. RESULTS: Five studies containing 413 patients met the inclusion criteria. There were no significant differences between the ACB and the PIA group in visual analog scale (VAS) score at rest (P = .14) and movement (P = .18), quadriceps muscle strength (P = .95), complications (P = .78), length of stay (LOS) (P = .54), and time up and go (TUG) test (P = .09), While patients in the ACB group had less equivalent morphine consumption (P < .05) compared with the PIA group. CONCLUSIONS: Our pooled data indicated the ACB group reduced the equivalent morphine consumption compared with the PIA group, with no statistically significant differences in the VAS score, quadriceps muscle strength, TUG test, complications, and LOS.

RESUMO

Introduction: Due to the increasing number of arthroplasties, the number of post-operative hospital days was reduced and the rate of rehabilitation accelerated. For this, proper postoperative analgesia is essential and the multimodal pain relief is an excellent tool. Aim: The aim of our study was to compare postoperative functional results, postoperative pain levels, and opioid analgesic needs of patients who received conventional and novel analgesic treatments. Method: In our prospective study, 81 patients were enrolled who underwent primary hip prosthesis surgery in our institution between February 2017 and January 2018. Of the randomized patients, 38 were in the control group and 43 in the multimodal pain group. We have tested their analgesic needs and the subjective pain levels of patients with the help of the visual analog scale (VAS). Results: Patients receiving multimodal pain relief had significantly lower opioid analgesic requirements and significantly lower VAS values assessed at 6 hours, and 3 and 4 days postoperatively. In addition, the patients in this group stayed in the hospital for a significantly shorter time after surgery. Conclusions: Based on our experience, multimodal pain relief in one-sided primary hip joint arthroplasty significantly reduced the patients' postoperative subjective pain sensation and pain killer consumptions.

RESUMO

Introduction: As the life expectancy and weight of patients are increasing, more old and obese patients are undergoing total knee arthroplasty (TKA). TKA may lead to several perioperative complications. These include anesthesia-related risks, exacerbation of comorbid medical issues and complications of surgical procedure. We have no studies reporting medical complications following TKA among our population. This study aimed to evaluate perioperative complications of TKA and to identify the related risk factors. Methods: It was a monocentric retrospective including 410 observations in the local TKA registry. Data of patients operated for primary unilateral TKA during the period from January 2014 to December 2017 were reviewed. All patients had standardized protocols of anesthesia and post operative care for three days following surgery. Multivariate logistic regression was used to identify the predicting factors for complications. Results: Incidence of perioperative complications was 37.1%. The most frequent were per operative hypotension (14.1%) and postoperative desaturation (21.7%, including pulmonary embolism in 2.4%). Multivariate logistic regression analysis identified: age ≥ 65 years (OR=1.9; p=0.006), respiratory diseases (OR=1.8; p=0.042) and general anesthesia (OR=2.8; p=0.009) as significant risk factors for any complications. Loss of autonomy (OR=4.8; p <0.001) and general anesthesia (OR=2.6; p=0.03) were significant risk factors for hypotension. Age ≥ 65 years (OR=2.6;p<0.001), female gender (OR=4.3;p=0.006) and respiratory diseases(OR=1.9;p=0.02) were associated with postoperative desaturation. Conclusion: This study highlighted hemodynamic and respiratory complications as the most common early complications in TKA. Age ≥ 65years, general anesthesia and respiratory diseases were significant risk factors.

RESUMO

BACKGROUND: Whether bipolar sealer (BS) is superior to standard electrocautery in patients with primary total knee arthroplasty (TKA) remains controversial. Thus, we conducted this meta-analysis involving comparative studies (S) to evaluate whether administration with BS (I) was associated with less blood loss (O) than standard electrocautery (C) after primary TKA (P). METHODS: PubMed (1950-January 2017), EMBASE (1974-January 2017), the Cochrane Library (January 2017 Issue 3), and the Google database (1950-January 2017) were systematically searched. Studies were included in accordance with Population, Intervention, Comparison, Outcomes, and Setting including criteria. Only the patients prepared for primary TKA and administrated with BS as the intervention group and standard electrocautery as control group were included in this meta-analysis. Outcomes include need for transfusion, total blood loss, blood loss in drainage, hemoglobin at discharge, hemoglobin drop, and length of hospital stay. Continuous outcomes and discontinuous outcomes were expressed as weighted mean difference (WMD) and risk ratio (RR) with corresponding confidence intervals (CIs), respectively. Stata 13.0 software was used for relevant data calculation. RESULTS: A total of 7 clinical trials with 718 patients (398 patients in BS group and 320 in standard electrocautery group) were finally included in this meta-analysis. The pooled results indicated that administration with BS was associated with little reduction of total blood loss (WMD = -123.80, 95%CI -236.56 to -11.04, P = .031). There was no significant difference between the need for transfusion, blood loss in drainage, hemoglobin at discharge, hemoglobin drop, and length of hospital stay (P > .05). CONCLUSION: Based on the current meta-analysis, we found no evidence to support the routine use of bipolar sealer in the management of blood loss in primary TKA. Since the poor quality of the included studies, more randomized controlled trials are still needed to further identify the efficacy of BS after primary TKA.

RESUMO

BACKGROUND: This study aimed to evaluate the effectiveness of continuous adductor canal block (CACB) versus continuous femoral nerve block (CFNB) in postoperative analgesia and early rehabilitation of patients with total knee arthroplasty (TKA). METHODS: The Cochrane Library, PubMed, and EMbase were systematically searched to retrieve literature comparing efficacy of CACB versus CFNB on pain relief and functional recovery in knee replacement patients until December 2018, without language limitation. Meta-analysis was performed using RevMan 5.3 software. RESULTS: A total of 7 clinical randomized controlled trials and 4 retrospective studies were included, involving 484 cases in the CACB group and 491 in the CFNB group. The results of the meta-analysis showed that the visual analogue scores (VAS) at rest were similar between the CACB group and the CFNB group at 8 hours (standard mean difference(SMD) = -0.26, 95% confidence interval(CI): -0.62, 0.11), 12 hours (SMD = -0.02, 95%CI: -0.50, 0.47), 24 hours (SMD = 0.05, 95%CI: -0.22, 0.33), and 48 hours (SMD = -0.10, 95%CI: -0.29, 0.09) after TKA (P > .05 for all). The muscle strength of patients in the CACB group post-operation was significantly improved than those of the CFNB group (SMD = 0.81; 95% CI: 0.35, 1.26; P = .0005). There were no significant differences in the amount of opioids consumption and the incidence of postoperative fall between CACB and CFNB (P > .05). CONCLUSION: The analgesic effects of CACB versus CFNB are equivalent after TKA. CACB has less effect on the quadriceps muscle strength, which is beneficial to the early postoperative activities and functional rehabilitation.

RESUMO

INTRODUCTION: Population ageing in developed countries will inevitably increase the need for knee and hip replacement surgery. Over the years, direct oral anticoagulants, such as rivaroxaban, have been widely used for thromboprophylaxis in patients undergoing knee and hip replacement surgery. The study of pharmacogenetic characteristics of rivaroxaban is important for enhancing the effectiveness and safety of rivaroxaban thromboprophylaxis. AIM: Evaluation of CYP3A4, CYP3A5 and ABCB1 gene polymorphisms influence on rivaroxaban pharmacokinetics and prothrombin time dynamics in patients undergoing total hip and knee replacement surgery. METHODS: The study included 78 patients undergoing total hip and knee replacement surgery. The patients received 10 mg of rivaroxaban once a day. Genotyping of polymorphisms ABCB1 rs1045642, ABCB1 rs4148738, CYP3A4 rs35599367 and CYP3A5 rs776746 was performed. Peak steady-state and trough steady-state rivaroxaban concentrations were determined. Prothrombin time was also evaluated. RESULTS: The study revealed the following haplotypes: (1) ABCB1 rs1045642-CYP3A4 rs35599367 and (2) ABCB1 rs4148738-CYP3A4 rs35599367. The analysis of the peak steady-state rivaroxaban concentration between mutant haplotypes and wild haplotypes revealed no significant differences. However, there was a statistically significant average correlation between peak steady-state rivaroxaban concentration and prothrombin time (r = 0.421; r2 = 0.178; p < 0.001). CONCLUSION: No significant difference was identified in peak steady-state rivaroxaban concentration between mutant haplotypes and wild haplotypes. The revealed statistically significant average correlation between the prothrombin time and peak steady-state rivaroxaban concentration is important in clinical practice for assessing the anticoagulant activity of rivaroxaban.

RESUMO

OBJECTIVES: Previous studies comparing adductor canal block (ACB) with femoral nerve block (FNB) are inconclusive with regard to patient-controlled analgesia (PCA) induced by opioids. Moreover, some postoperative pain severity results differ between previous randomized controlled trials (RCTs). The primary aim of the current study was to compare total intravenous morphine consumption administered via PCA during the first postoperative day in continuous FNB and ACB groups after total knee arthroplasty (TKA). Secondary aims included evaluation of postoperative pain via a visual analog scale, degree of knee extension, quadriceps muscle strength, and ability to sit, stand upright, and walk. METHODS: The study was a RCT. Inclusion criteria were presence of gonarthrosis, age >18 and <75 years, and scheduled for TKA under single-shot spinal anesthesia. RESULTS: A number of morphine uses was lower in the FNB group than in the ACB group (14, range 12-15 vs 20, range 18-22; P = .0001), and they perceived less severe pain at the 8th (P = .00003) and 24th hours. However, ACB was significantly superior with regard to most of the other parameters pertaining to mobility, including muscle strength at the 8th and 24th hours, degree of knee extension at the 8th hour, sitting at the 8th hour, standing upright at the 24th hour, and walking at the 24th and 48th hours. DISCUSSION: FNB was associated with the perception of less severe pain after TKAs. However, ACB was associated with earlier mobility rehabilitation.

RESUMO

AIMS: The aim of this study was to conduct the largest low contact stress (LCS) retrieval study to elucidate the failure mechanisms of the Porocoat and Duofix femoral component. The latter design was voluntarily recalled by the manufacturer. MATERIALS AND METHODS: Uncemented LCS explants were divided into three groups: Duofix, Porocoat, and mixed. Demographics, polyethylene wear, tissue ingrowth, and metallurgical analyses were performed. RESULTS: In 104 implants, a decrease in the odds of loosening and an increase in metallosis and tissue staining in the Duofix group relative to Porocoat group was detected (p = 0.028). There was an increased presence of embedded metallic debris in the Duofix group (p < 0.001). Decreased tissue ingrowth was associated with the Duofix surface (p < 0.001). The attached beads had reduced microhardness, indicative of adverse thermal processing, which resulted in bead shedding, particulate debris, and metallosis. CONCLUSION: Hydroxyapatite coating of the LCS femoral component produced unexpected results and led to its recall. The root cause was likely a combination of retained alumina grit and a reduction in bead microhardness (mechanical strength) resulting in increased particle debris, metallosis, and early revision. The Duofix LCS femoral component was not equivalent to the Porocoat version despite its approval through the Food and Drug Administration (FDA) 510(k) equivalance approval process. Regulation of the introduction of modified existing devices needs to be improved and the Duofix LCS should have been considered to be a new device for which equivalence had not been demonstrated at the point of introduction.

RESUMO

AIMS: The aim of this study was to assess the effect of posterior cruciate ligament (PCL) resection on flexion-extension gaps, mediolateral soft-tissue laxity, fixed flexion deformity (FFD), and limb alignment during posterior-stabilized (PS) total knee arthroplasty (TKA). PATIENTS AND METHODS: This prospective study included 110 patients with symptomatic osteoarthritis of the knee undergoing primary robot-assisted PS TKA. All operations were performed by a single surgeon using a standard medial parapatellar approach. Optical motion capture technology with fixed femoral and tibial registration pins was used to assess gaps before and after PCL resection in extension and 90° knee flexion. Measurements were made after excision of the anterior cruciate ligament and prior to bone resection. There were 54 men (49.1%) and 56 women (50.9%) with a mean age of 68 years (sd 6.2) at the time of surgery. The mean preoperative hip-knee-ankle deformity was 4.1° varus (sd 3.4). RESULTS: PCL resection increased the mean flexion gap significantly more than the extension gap in the medial (2.4 mm (sd 1.5) vs 1.3 mm (sd 1.0); p < 0.001) and lateral (3.3 mm (sd 1.6) vs 1.2 mm (sd 0.9); p < 0.01) compartments. The mean gap differences after PCL resection created significant mediolateral laxity in flexion (gap difference: 1.1 mm (sd 2.5); p < 0.001) but not in extension (gap difference: 0.1 mm (sd 2.1); p = 0.51). PCL resection significantly improved the mean FFD (6.3° (sd 4.4) preoperatively vs 3.1° (sd 1.5) postoperatively; p < 0.001). There was a strong positive correlation between the preoperative FFD and change in FFD following PCL resection (Pearson's correlation coefficient = 0.81; p < 0.001). PCL resection did not significantly affect limb alignment (mean change in alignment: 0.2° valgus (sd 1.2); p = 0.60). CONCLUSION: PCL resection creates flexion-extension mismatch by increasing the flexion gap more than the extension gap. The increase in the lateral flexion gap is greater than the increase in the medial flexion gap, which creates mediolateral laxity in flexion. Improvements in FFD following PCL resection are dependent on the degree of deformity before PCL resection. Cite this article: Bone Joint J 2019;101-B:1230-1237.

RESUMO

RATIONALE: Unicompartmental knee arthroplasty (UKA) is an effective method to treat single compartment disease of the knee joint. Report about the complications of UKA, especially tibial plateau fractures, is rare. Given its rarity, its pathogenesis is not well described, and a standard of treatment is still not established. Therefore, relevant studies and analysis of this complication have a significant effect on helping physicians avoid risks and guide clinical diagnosis and treatment. PATIENT CONCERNS: The 1st case corresponds to a 70-year-old male patient who complained of knee pain, difficulty walking, nocturnal rest pain, and elevated skin temperature at 3 weeks after the left knee arthroplasty. The second case is a 72-year-old female patient who complained of left knee pain and swelling during movement at 2 weeks after the left knee arthroplasty. DIAGNOSIS: The 1st case showed a fracture of the medial malleolus of the left knee and a secondary depression of the medial tibial plateau in X-rays and the second case showed a fracture of the medial malleolus of the left knee in computed tomography (CT) and X-rays. INTERVENTIONS: The 1st case was treated with plate and screw fixation and the second case was treated conservatively and immobilized using brace and remained nonweight bearing for 6 weeks. OUTCOMES: After 1 year, both patients have good joint activity, and there was no pain or loosening of the prosthesis and fragment displacement. LESSONS: The incidence of tibial plateau fractures (TPF) related to UKA might be low, but fatal and difficult to treat. Its pathogenesis determines procedure-related factors; when fracture develops, treatment should be based on the degree of displacement, stability of implant fixation, etc.

RESUMO

BACKGROUND: The local injection of multimodal cocktail is currently commonly used in the treatment of postoperative pain after total knee arthroplasty (TKA). It is still inconclusive whether the morphine added to the intraoperative injection mixture could make some difference. This meta-analysis aimed to evaluate the efficacy and safety of additional morphine injection on postoperative analgesia in TKA, and provide some useful information on morphine usage in clinical practice. METHODS: The randomized controlled trials (RCTs) in databases including PubMed, Web of Science, Embase, Cochrane Library, Chinese biomedical literature database (CBM), and Chinese National Knowledge Infrastructure (CNKI) databases were systematically searched. Of 623 records identified, 8 RCTs involving 1093 knees were eligible for data extraction and meta-analysis according to criteria included. RESULTS: Meta-analysis showed that the use of local morphine injection was not associated with significant pain relief within 48 hours postoperatively at rest and on motion (P > .05, all). The use of morphine reduced postoperative total systemic opioids consumption (P < .05). This study found no significant differences in other outcomes including knee flexion range of motion (ROM) (P > .05), extension ROM (P > .05), The Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores (P > .05), Post-operative nausea and vomiting occurrence (P > .05) regardless of the presence of morphine or not in the injections. CONCLUSION: Additional morphine added to multimodal cocktail did not decrease the postoperative pain scores significantly based on our outcomes, but it reduced the systemic postoperative opioids consumption in total knee arthroplasty.

RESUMO

BACKGROUND: While increased surgical-provider volume has been associated with improved outcomes, research regarding volume-outcome relationships within high-volume institutions and the role of anaesthesiologists is limited. Further, the effect of anaesthesia-care-team composition remains understudied. This analysis aimed to identify the impact of anaesthesiologist and surgeon volume on adverse events after total joint arthroplasties. METHODS: We retrospectively identified 40 437 patients who underwent total joint arthroplasties at a high-volume institution from 2005 to 2014. The main effects of interest were anaesthesiologist and surgeon volume and experience along with anaesthesia-care-team composition. Multivariable logistic regression models were used to evaluate three outcomes: any complication, cardiopulmonary complication, and length of stay (>5 days). Odds ratios (ORs) and 99.75% confidence intervals (CIs) were reported. RESULTS: Across all three models, anaesthesiologist volume and experience, and anaesthesia-care-team composition were not significant predictors. Surgeon annual case volume >50 was associated with significantly reduced odds of any complication (annual case volume: 50-149; OR: 0.80; CI: 0.66-0.98) and prolonged length of stay (OR: 0.69; CI: 0.60-0.80). Surgeon experience >20 yr was associated with significantly reduced odds of prolonged length of stay (OR: 0.85; CI: 0.75-0.95). CONCLUSIONS: Anaesthesiologist volume and experience, and anaesthesia-care-team composition did not impact the odds of an adverse outcome, although a higher surgeon volume was associated with decreased odds of complications and prolonged length of stay. Further study is necessary to determine if these findings can be extrapolated to less specialised, lower volume surgical settings.

RESUMO

AIMS: Antifibrinolytic agents, including tranexamic acid (TXA) and epsilon-aminocaproic acid (EACA), have been shown to be safe and effective for decreasing perioperative blood loss and transfusion following total hip arthroplasty (THA) and total knee arthroplasty (TKA). However, there are few prospective studies that directly compare these agents. The purpose of this study was to compare the benefits of intraoperative intravenous TXA with EACA. PATIENTS AND METHODS: A total of 235 patients (90 THA and 145 TKA) were enrolled in this prospective, randomized controlled trial at a single tertiary-care referral centre. In the THA cohort, 53.3% of the patients were female with a median age of 59.8 years (interquartile range (IQR) 53.3 to 68.1). In the TKA cohort, 63.4% of the patients were female with a median age of 65.1 years (IQR 59.4 to 69.5). Patients received either TXA (n = 119) or EACA (n = 116) in two doses intraoperatively. The primary outcome measures included change in haemoglobin level and blood volume, postoperative drainage, and rate of transfusion. Secondary outcome measures included postoperative complications, cost, and length of stay (LOS). RESULTS: TKA patients who received EACA had greater drainage (median 320 ml (IQR 185 to 420) vs 158 ml (IQR 110 to 238); p < 0.001), increased loss of blood volume (891 ml (IQR 612 to 1203) vs 661 ml (IQR 514 to 980); p = 0.014), and increased haemoglobin change from the preoperative level (2.1 ml (IQR 1.7 to 2.8) vs 1.9 ml (IQR 1.2 to 2.4); p = 0.016) compared with patients who received TXA. For the THA cohort, no statistically significant differences were observed in any haematological outcome measure. One patient in the EACA group required transfusion. No patient in the TXA group required transfusion. There were no statistically significant differences in number or type of postoperative complications or LOS for either THA or TKA patients regardless of whether they received TXA or EACA. CONCLUSION: For hip and knee arthroplasty procedures, EACA is associated with increased perioperative blood loss compared with TXA. However, there is no significant difference in transfusion rate. While further prospective studies are needed to compare the efficacy of each agent, we currently recommend orthopaedic surgeons to select their antifibrinolytic based on cost and regional availability.

RESUMO

AIMS: The aim of this study was to assess the effects of transferring patients to a specialized arthroplasty centre between the first and second stages (interstage) of prosthetic joint infection (PJI) of the knee. PATIENTS AND METHODS: A search of our institutional database was performed to identify patients having undergone two-stage revision total knee arthroplasty (TKA) for PJI. Two cohorts were created: continuous care (CC) and transferred care (TC). Baseline characteristics and outcomes were collected and compared between cohorts. RESULTS: A total of 137 patients were identified: 105 in the CC cohort (56 men, 49 women; mean age 67.9) and 32 in the TC cohort (17 men, 15 women; mean age 67.8 years). PJI organism virulence was greater in the CC cohort (36.2% vs 15.6%; p = 0.030). TC patients had a higher rate of persisting or recurrent infection (53.6% vs 13.4%; p < 0.001), soft-tissue complications (31.3 vs 14.3%; p = 0.030), and reduced requirement for porous metal augments (78.1% vs 94.3%; p = 0.006). Repeat first stage debridement after transfer led to greater need for plastic surgical procedures (58.3% vs 0.0%; p < 0.001). CONCLUSION: Patient transfer during the interstage of treatment for infected TKA leads to poorer outcomes compared with patients receiving all their treatment at a specialized arthroplasty centre.

RESUMO

BACKGROUND: Days alive and out of hospital (DAH) has been proposed as a pragmatic outcome measure of surgical quality. However, there is a lack of procedure specific data or data within an optimised fast-track protocol. Furthermore, information about influence of follow-up duration and types of complications on DAH is limited. METHODS: Observational multicentre cohort study of patients undergoing fast-track total hip (THA) and knee arthroplasty (TKA). Prospective information on comorbidity and complete 90 days follow-up was undertaken through the Danish National Patient Register and chart review. RESULTS: For 16 137 procedures, of which 18.6% were high-risk (≥2 preoperative risk factors), the median length of stay was 2 days (inter-quartile range [IQR], 2-3), and 30- and 90-day readmission rates were 5.7% and 8.1%, respectively. Median DAH30 and DAH90 days were 27 (26-28) and 87 (85-88) vs 28 (27-28) and 88 (87-89) (P<0.001) in high-vs low-risk patients, respectively. The fraction with DAH ≤25 at 30 days and DAH ≤85 at 90 days was increased in high-vs low-risk patients: 23.3% vs 6.8% (odds ratio [OR]=4.16; 95% confidence interval [CI], 3.73-4.65) and 26.0% vs 8.6% (OR=3.75; 95% CI, 3.38-4.16). There were relatively fewer 'surgical' complications in high- vs low-risk patients with DAH30 ≤25 (14.6% vs 25.8%) (OR=0.49; 95% CI, 0.37-0.65) and DAH90 ≤85 (16.9% vs 31.89%) (OR=0.43; 95% CI, 0.34-0.56). About 2% of patients had readmissions, but DAH was >25 and >85 at 30 and 90 days after operation, respectively. CONCLUSION: Median DAH in fast-track THA/TKA patients is 28 at 30 days and 88 at 90 days after surgery. DAH in high-risk patients was only slightly reduced compared with low-risk patients, but they have relatively more 'medical' complications.
