Abstract
OBJECTIVE To evaluate the efficacy and safety of topical glucocorticoids for total hip arthroplasty by meta-analysis. METHODS A computerized search of the Cochrane Library, MEDLINE, EMBASE, and PubMed English databases, as well as Chinese Biomedical Literature Database, vipu Chinese Science and Technology Journal Database, Wanfang database, and Chinese Knowledge Net Database, was performed to include all randomized controlled trials (RCTs) regarding topical glucocorticoid therapy for postoperative bleeding after THA according to the inclusion criteria. The quality evaluation criteria of RCTs, as stated in the Cochrane Handbook for Systematic Reviews of Interventions 4.2.5, were adopted for evaluation, and the meta-analysis was performed using RevMan 5.3. RESULTS A total of 10 articles were included, including 1,112 patients: 566 in the topical glucocorticoid group and 546 in the control group. The transfusion rate was 8.43% for topical glucocorticoids and 30.05% for the control group (P < 0.001), and topical glucocorticoids reduced 317.89 ml total blood loss and 76.82 ml invisible blood loss, with statistically significant differences (P < 0.001). The amount of intraoperative blood loss was reduced by topical glucocorticoids, but the difference was not statistically significant (P=0.83), and the postoperative HB value was increased by topical glucocorticoids, although the difference was statistically significant (P < 0.001). The incidence of DVT and PE after topical glucocorticoid application (3.03%) was greater than that of the control group (2.40%), the difference was not statistically significant (P=0.54), and the incidence of infection after topical glucocorticoid application (3.03%) was greater than that of the control group (2.40%). The difference was not statistically significant (P=0.39). CONCLUSIONS Topical glucocorticoids can reduce the transfusion rate and blood loss in THA patients without increasing their risk of thrombosis.

Abstract
INTRODUCTION Traditional fully cemented prosthesis for total knee arthroplasty (TKA) has many disadvantages. Current studies have shown that the effects of mixed fixation TKA are the same as or even better than those of fully cemented TKA. We aimed to compare the total blood loss (TBL) in the two fixation types of TKA and the hemostatic effects of different doses of tranexamic acid (TXA) for reverse hybrid TKA. METHODS From September 2018 to November 2020, 233 patients with knee osteoarthritis undergoing unilateral TKA were randomly divided into four groups: groups 1 and 2: fully cemented TKA + intra-articular injection (IAI) of either 1 g TXA (n = 54) or 2 g TXA (n = 60); groups 3 and 4: reverse hybrid TKA + IAI of either 1 g TXA (n = 56) or 2 g TXA (n = 63). All patients were administered intravenous drip of TXA (20 mg/kg) as the basic drug. Perioperative and follow-up data of all patients were compared. RESULTS The TBL in groups 1, 2, and 3 was higher than that in group 4 (P < 0.0001). The TBL in group 1 was significantly less than that in group 3 (P < 0.05). Although there was no significant difference in blood transfusion demand among the four groups (P > 0.05), the number of anemic patients who did not meet the standard of blood transfusion in group 4 decreased significantly (P < 0.0001). There was no significant difference in pain, function or thrombotic complications among all patients. CONCLUSION The TBL in reverse hybrid TKA is larger than in fully cemented TKA. For reverse hybrid TKA, the hemostatic effect of TXA with 2 g of IAI was significantly better than with 1 g. Although this method does not reduce the need for blood transfusion, it can significantly reduce the incidence of postoperative anemia.

PloS one. 2019;14(7):e0220392
Abstract
BACKGROUND Arthroscopic repair of rotator cuff tears, although commonly performed, carries the risk of retears. Therefore, bioremediation techniques such as platelet-rich plasma injections have been used as adjuvant therapies. The clinical efficacy of platelet-rich plasma in the arthroscopic repair of full-thickness rotator cuff injury is controversial. We performed a meta-analysis to evaluate the clinical effectiveness and safety of platelet-rich plasma and provide evidence-based medical recommendations for selecting the proper clinical treatment plan for full-thickness rotator cuff injuries. METHODS A search for the terms "platelet-rich plasma" and "rotator cuff" was performed in the PubMed, EMBASE, and Cochrane Library databases using a computer. After conducting quality evaluations and data extraction, RevMan 5.3 software was used to combine the effect sizes, and the GRADEpro Guideline Development Tool was used to rate the level of evidence from aspects of functional score, pain score and retear rate. RESULTS Eight randomized controlled trials involving 566 patients were included. The long-term retear rate(RR = 0.96, 95% CI [0.52, 1.78], P = .89), Constant score(RR = 0.96, 95% CI [0.52, 1.78], P = .89), and Visual Analog Scale score for pain (SMD = -0.28, 95% CI [-0.60, 0.04], P = .08), as well as both the long-term and short-term Disabilities of the Arm, Shoulder, and Hand scores(SMD = -0.13, 95% CI [-0.44, 0.18], P = .41;SMD = -0.02, 95% CI [-0.40, 0.36], P = .93), were not significantly different between the platelet-rich plasma and control groups. However, the short-term retear rate(RR = 0.29, 95% CI [0.13, 0.65], P = .003) and Visual Analog Scale score (SMD = -0.41, 95% CI [-0.62, -0.19], P = .0002) were significantly lower, while the short-term Constant score(SMD = 0.37, 95% CI [0.19, 0.55], P < .0001) and short-term and long-term University of California at Los Angeles activity scores (SMD = 0.38, 95% CI [0.16, 0.60], P = .0008;SMD = 0.85, 95% CI [0.48, 1.22], P < .00001) were significantly higher, in the platelet-rich plasma group than in the control group. CONCLUSION Platelet-rich plasma injection can effectively improve the short-term outcomes following arthroscopic repair of full-thickness rotator cuff tears, thus reducing the rate of retears, alleviating pain, and improving patients' shoulder function. Specifically, the clinical outcomes are better with the use of platelet-rich plasma in single-row fixation than in other fixation techniques. Therefore, platelet-rich plasma injection can be recommended as an adjuvant therapy in single-row repair for improved short-term results.

Zhang S, Wang C, Shi L, Xue Q
Medicine. 2019;98(30):e16570
Abstract
BACKGROUND Perioperative bleeding during total knee arthroplasty (TKA) is an ongoing problem for surgeons. Intravenous or topical application of tranexamic acid (TXA) can effectively stop bleeding, but there is still no uniform standard for the best method of administration and dose. METHODS From October 2016 to September 2018, 218 patients with unilateral primary knee osteoarthritis requiring knee replacement were enrolled and randomly divided into four groups. Group 1 (n = 55) received intra-articular injection (IAI) of TXA and peri-articular injection (PAI) of placebo, group 2 (n = 55) received IAI of placebo and PAI of TXA, group 3 (n = 51) received IAI of TXA and PAI of TXA, and group 4 (n = 57) received double placebo (IAI of placebo and PAI of placebo). The demographic characteristics, surgical indices, hematological indices, wound healing history, and thromboembolic events were investigated. RESULTS Eight patients were lost to follow-up and 210 patients were included in the analysis. The median TBLs in patients who received IAI of TXA and PAI of placebo and those who received IAI of placebo and PAI of TXA were 470.81 ml and 481.54 ml, respectively. These TBL levels were significantly higher compared to those in patients who received IAI of TXA and PAI of TXA (359.18 ml, P ≤ .001), but significantly lower compared to those in patients who received the double placebo (522.71 ml, P ≤ .001). Compared to other groups, more patients in the double placebo group needed a blood transfusion (P = .013). In the short-term, the double placebo group had higher VAS pain scores and less ROM after surgery (P = .011 and P = .001, respectively). In the long-term (6-month follow-up), there were no significant differences in ROM, VAS, DVT, PE, or wound-related complications. CONCLUSION The combined use of IAI and PAI of TXA can significantly reduce the TBL and the need for blood transfusion without delaying wound healing or increasing the risk of DVT and PE. In the short-term after surgery, this combined method reduces the pain VAS scores and improves the ROM; however, there are no long-term effects on VAS and ROM.

Journal of orthopaedic translation. 2019;19:1-11
Abstract
Objective: The present meta-analysis was conducted to compare the efficacy and safety of intravenous application of tranexamic acid (TXA) with placebo in patients with hip fracture undergoing hip surgeries. Methods: PubMed, EMBASE and Cochrane Library were searched from inception until March 2018. A combined searching strategy of subject words and random words was adopted. Only randomized clinical trials were included. The comparisons regarding transfusion rate, total blood loss, intraoperative blood loss, postoperative blood loss, postoperative haemoglobin and postoperative thromboembolic complications were conducted. The meta-analysis was performed using Review Manager 5.3, and the bias evaluation was based on the Cochrane Handbook 5.1.0. Results: Ten randomized controlled trials published from 2007 to 2018 were included in the meta-analysis. The results showed that there were significant differences in the two groups concerning transfusion rate of allogeneic blood [risk ratio (RR) = 0.66, 95% confidence interval (CI): 0.56 to 0.78, P = 0.003], total blood loss [mean difference (MD) = -273.00, 95% CI: -353.15 to -192.84, P < 0.00001], intraoperative blood loss (MD = -76.63, 95% CI: -139.55 to -13.71, P = 0.02), postoperative blood loss (MD = -125.29, 95% CI: -221.96 to -28.62, P = 0.01) and postoperative haemoglobin (MD = 0.80, 95% CI: 0.38 to 1.22, P = 0.0002). Nonsignificant differences were found in the incidence of thromboembolic events (RR = 1.38, 95% CI: 0.74 to 2.55, P = 0.31). Conclusions: This meta-analysis of the available evidence implies that the intravenous route of TXA shows an ability to reduce transfusion requirements and total blood loss, not increasing the incidence of thromboembolic events in patients undergoing hip surgeries. The translational potential of this article: The result of this meta-analysis shows that the utilization of intravenous TXA in patients with hip fracture undergoing hip surgeries possesses great potential in reducing blood loss and allogeneic blood transfusion safely.

Comparison of tourniquet application only during cementation and long-duration tourniquet application in total knee arthroplasty: a meta-analysis
Wang C, Zhou C, Qu H, Yan S, Pan Z
Journal of Orthopaedic Surgery and Research. 2018;13((1)):216.
Abstract
BACKGROUND Tourniquet is widely used by orthopedic surgeons in total knee arthroplasty (TKA). However, there are still controversies on the optimal timing of tourniquet application. The aim of this meta-analysis was to compare the effect and safety of tourniquet application only during cementation with long-duration tourniquet application in TKA. METHODS An electronic literature search of PubMed, the Cochrane library, Embase, and Web of Science was conducted in July 2017. All randomized controlled trials (RCTs) comparing tourniquet application only during cementation with long-duration tourniquet application in TKA were included. RevMan 5.3 software was selected to perform the meta-analysis. RESULTS Seven studies involving 440 TKAs were included for meta-analysis. The results suggested that although significant less intraoperative and total blood loss were observed with long-duration tourniquet application, tourniquet application only during cementation would not increase the number of transfusion and operation time. Tourniquet application only during cementation results in less knee pain on post-operative day 1 (POD 1), less time needed to achieve straight-leg raise, and less minor complications following TKA. CONCLUSIONS Tourniquet application only during cementation might reduce the rate of minor complications and have faster functional recovery during the early rehabilitation period following TKA, but it could not limit intraoperative and total blood loss. No definitive conclusions can be drawn based on the current evidences. Further, large well-designed RCTs with extensive follow-up are still needed to validate this research.

Single-dose tranexamic acid for reducing bleeding and transfusions in total hip arthroplasty: a double-blind, randomized controlled trial of different doses
Wang C, Kang P, Ma J, Yue C, Xie J, Pei F
Thrombosis Research. 2016;141:119-123.
Abstract
BACKGROUND Tranexamic acid can be effective at decreasing blood loss and transfusion requirements associated with total hip arthroplasty (THA), but few studies have compared the efficacy of different intravenous dosing regimes. This double-blind, randomized controlled trial compared the ability of two doses of intravenous TXA (IV-TXA, 10 or 15mg/kg) to reduce bleeding and transfusions associated with THA. MATERIALS AND METHODS A total of 124 patients scheduled for THA were consecutively randomized 1:1:1 into three parallel arms: control (placebo), 10mg/kg IV-TXA and 15mg/kg IV-TXA. RESULTS The proportion of patients who experienced bleeding and required transfusions was significantly lower in the 15mg/kg IV-TXA group (1 of 42, 2.4%) than in the 10mg/kg IV-TXA group (8 of 39, 20.5%; P=0.012) and in the control group (10 of 38, 26.3%; P=0.002). In fact, this proportion was similar between the 10mg/kg IV-TXA and control groups (P=0.547). Ultrasound examination on postoperative day 3 revealed only one case of asymptomatic deep vein thrombosis (in the femoral vein) in the 10mg/kg IV-TXA group, which was managed by administering low-molecular-weight heparin. No cases of deep-vein thrombosis were observed in the other two groups. No cases of symptomatic pulmonary embolism were observed. CONCLUSION IV-TXA at 10mg/kg significantly reduced blood loss and mitigated the decrease in hemoglobin and hematocrit after THA, but it did not significantly reduce the need for transfusions. In contrast, a dose of 15mg/kg reduced both bleeding and transfusion requirements. Our results argue for a dose of 15mg/kg when using single-dose IV-TXA. LEVEL OF EVIDENCE Therapeutic Level I.

International Journal Of Surgery. 2015;15:134-9
Abstract
OBJECTIVE A systematic review of randomized controlled trials (RCTs) and non-RCTs was performed to evaluate efficacy for the reduction of postoperative blood loss and transfusion requirements of topical use of tranexamic acid in patients undergoing primary total hip arthroplasty. METHOD Potential articles were identified from Medline (1966 - September 2014), Embase (1980 - September 2014), Pubmed (1980 - September 2014) and The Cochrane Central Register of Controlled Trials. Other internet databases are also searched to find trials according to the Cochrane Collaboration guidelines. Moreover, gray literatures are also selected from the reference list of the included studies. High quality randomized controlled trials (RCTs) and non-RCTs were selected. The software RevMan 5.1 was used for the mate-analysis. RESULTS Four RCTs and four non-RCT meet the inclusion criteria. There were significant differences in hemoglobin, total blood loss, transfusion requirements and postoperative drainage volume between TXA groups and control groups. There were no significant differences in length of stay, incidence of wound infection, deep vein thrombosis (DVT) and pulmonary embolism (PE) between treatment and control groups. CONCLUSIONS Present meta-analysis indicates that the antifibrinolytic agent, also known as tranexamic acid, could reduce hemoglobin decline, volume of drainage, total blood loss and transfusion requirements after THA, and is not related to adverse reactions or complications such as wound infection, DVT and PE.Copyright 2015 Surgical Associates Ltd.

Wang C, Han Z, Zhang T, Ma JX, Jiang X, Wang Y, Ma XL
Journal of Orthopaedic Surgery. 2014;9:90.
Abstract
PURPOSE Total knee arthroplasty (TKA) is a popular procedure in severe osteoarthritis. But perioperative bleeding remains a problem. Floseal is a mixture of thrombin and bovine gelatin which can benefit a lot on reducing intraoperative and postoperative bleeding. However, there is no enough evidence judging its safety and efficiency. So a meta-analysis is conducted by us to evaluate the efficacy and safety of a thrombin-based hemostatic agent compared with conventional methods in TKA. METHOD Two independent reviewers selected literatures published before August 2014 from MEDLINE, Embase, and The Cochrane Central Register of Controlled Trials. Other internet databases were also performed to identify trials according to the Cochrane Collaboration guidelines. High-quality randomized controlled trials (RCTs), prospective control trials (PCTs), and case controlled trials (CCTs) were selected. The meta-analysis was undertaken using RevMan 5.1 for Windows. RESULTS Three RCTs, one PCT, and one CCT met the inclusion criteria. There were significant differences in hemoglobin decline and calculated total blood loss between the Floseal group and control group. There were no significant differences in postoperative drainage volume, rate of transfusion requirement, incidence of wound infection, deep vein thrombosis (DVT), and pulmonary embolism (PE) between treatment and control groups. CONCLUSIONS The present meta-analysis indicates that a thrombin-based hemostatic agent can reduce hemoglobin decline and calculated total blood loss after TKA and is not related to adverse reactions or complications such as wound infection, DVT, and PE.
