Arthroplasty (London, England). 2021;3(1):29
Abstract
BACKGROUND Tourniquet application is expected to improve surgery exposure and cementation process in total knee arthroplasty (TKA) but its effectiveness remains controversial and needs to be further explored. The aim of this meta-analysis was to assess the effect of tourniquet in primary TKA. The hypothesis is that the tourniquet application affects the cement penetration in TKA. METHODS A search was conducted in PubMed, Embase, and the Cochrane Library for the potentially eligible articles. Two independent researchers reviewed the articles retrieved against the pre-designed inclusion and exclusion criteria. In primary TKA, cement penetration was assessed, and the data between the tourniquet-assisted and non-tourniquet-assisted TKAs were compared. Statistical significance was set at P < 0.05. RESULTS A total of 4 randomized controlled trials and 3 non-randomized controlled trials (involving 675 patients) were included. There was no significant difference between the tourniquet-assisted and non-tourniquet-assisted TKAs in terms of cement penetration (P > 0.05). There were no significant differences in the total surgical time, blood loss, blood transfusion, the Knee Society Score, and the visual analogue scale (VAS) between the two kinds of procedures (P > 0.05). CONCLUSIONS Tourniquet application may not affect cement penetration in primary TKA and may not help reduce blood loss, ease knee pain or improve the knee function. A surgeon may choose to use a tourniquet or not according to his or her own preference. LEVEL OF EVIDENCE Level Ib, meta-analysis.

Nursing open. 2021;8(1):80-86
Abstract
AIM: To identify the effect of enhanced recovery after surgery (ERAS) and rapid rehabilitation concepts on the outcomes of patients with haemophilia A undergoing total knee arthroplasty. DESIGN Randomized controlled trial. METHODS The primary endpoint was postoperative hospital stay. The secondary endpoints were pain scores, joint function scores, haemoglobin levels at 3 and 7 days after surgery and satisfaction with hospitalization. RESULTS Thirty-two patients were enrolled. Compared with the routine nursing group, the ERAS group showed shorter postoperative hospital stay (14.2 SD 0.8 vs. 16.6 ± 1.3 days, p < .001), smaller amounts of blood transfusion (924 SD 317 vs. 1,263 SD 449 ml, p = .020) and coagulation factors (37,325 SD 5,996 vs. 48,475 SD 8,019 U, p < .001), lower pain scores at 3 (3.3 SD 0.7 vs. 4.3 SD 0.7, p = .002) and 7 (2.3 SD 0.7 vs. 2.8 ± 0.5, p = .015) days, lower hospital for special surgery knee scores at 3 (59.9 SD 7.8 vs. 53.6 SD 5.9, p = .016) and 7 (77.9 SD 6.9 vs. 71.1 ± 7.1, p = .009) days and higher satisfaction with hospitalization (94.3 SD 1.4 vs. 92.7 SD 1.6, p = .004).

Journal of shoulder and elbow surgery. 2020;29(7):1375-1379
Abstract
BACKGROUND Elbow joint open arthrolysis is an effective method to release contracted tissue and débride heterotopic ossification in cases of post-traumatic elbow stiffness. Recurrence remains one of the most common concerns for surgeons. Soft tissue contracture may result from intra- and/or extra-articular bleeding, edema, effusion, and granulation. The increasing incidence of intraoperative and postoperative bleeding has caused uncertainty about surgical outcomes. Tranexamic acid (TXA) is effective for reducing surgery-related bleeding and effusions in total hip or knee arthroplasty. PURPOSE To investigate whether topical TXA can decrease blood loss and effusions in patients treated with elbow joint open arthrolysis and whether it affects final function. PATIENTS AND METHOD A prospective comparative study was conducted. Sixty-one patients with joint stiffness were enrolled and randomly divided into 2 groups: one consisting of 31 patients treated with topical TXA intraoperatively after open arthrolysis (experimental group) and the other consisting of 30 patients who received saline administration (control group). The operation time, tourniquet time, and intraoperative blood loss were recorded. Drainage volume, elbow rotation, elbow motion arc, Mayo Elbow Performance Score, and operation-related complications were followed up and recorded, whereas hematoma volume remaining in the joint space after drainage tube removal was assessed on ultrasonography. RESULTS Tourniquet time, intraoperative blood loss, and postoperative drainage were significantly lower in the TXA group than in the control group. However, no significant intergroup differences were found in the incidence of related complications and final function evaluated at the final follow-up. CONCLUSION Topical TXA improves surgical quality by controlling intraoperative bleeding, decreases the amount of blood loss soon after surgery, and could become a routine procedure in elbow joint open arthrolysis.

Abstract
BACKGROUND Due to differences in pharmacological mechanism of action, the effect of tranexamic acid (TA) on aspirin-related bleeding remains unknown. We therefore conducted a prospective randomized study to elucidate: (1) the effect of topical TA administration on blood loss and transfusion rate in total hip arthroplasty (THA) patients receiving continuous aspirin for prevention of cardiovascular or cerebrovascular events; (2) 90-day complications of topical TA administration; (3) possible variables contributing to blood transfusion. HYPOTHESIS Topical TA administration reduces blood loss and transfusion rate in THA patients receiving continuous aspirin. PATIENTS AND METHODS A total of 102 consecutive THA patients taking continuous aspirin were enrolled and randomized into two groups. In the topical TA (TTA) group (n=55), topical TA was administered at three points during THA; in the control group (n=47), the patients received saline solution as placebo. Based on drop in hemoglobin concentration, total estimated blood loss was calculated as the main assessment criterion. Secondary assessment criteria included transfusion rate and 90-day complications. Finally, a multivariate regression model was used to assess possible predictive factors for blood transfusion. RESULTS (1) Significantly lower total blood loss was observed in the TTA group than in the control group (897+/-177ml vs. 1153+/-345ml, p<0.001). Furthermore, lower transfusion rate was observed in the TTA group than in the control group (10.9% vs. 34.0%, p=0.005). (2) No significant difference was observed between the two groups regarding 90-day complications. (3) We identified higher preoperative hemoglobin level (OR=0.675, p=0.002) and topical TA administration (OR=0.002, p=0.012) as negative predictive factors for blood transfusion. DISCUSSION Topical application of TA was safe and beneficial in THA patients receiving continuous aspirin for prevention of cardiovascular or cerebrovascular events, to reduce blood loss and transfusion rate, without increasing the risk of 90-day complications.

Abstract
OBJECTIVE To investigate the safety and efficiency of intravenous tranexamic acid (TXA) to reduce blood loss in total knee arthroplasty (TKA). METHODS A prospective, randomized, self-controlled study was carried out on 60 patients scheduled for bilateral TKA between January 2012 and December 2013. TXA (10 mg/kg) was injected intravenously approximately 10 minutes before tourniquet release when TKA was performed on one side (TXA group), and TXA was not used on the other side (control group). No significant difference was found in the preoperative hemoglobin (Hgb), platelet (PLT) count, prothrombin time (PT), and activated partial thromboplastin time (APTT) between 2 groups (P > 0.05). The amount of drainage, the total blood loss, the hidden blood loss, the postoperative Hgb, the amount of blood transfusion, the ratio of blood transfusion, and the incidence of vein thrombosis embolism (VTE) were compared between 2 groups. RESULTS The amount of drainage and total blood loss were significantly less in the TXA group than in control group (P < 0.05), and the Hgb was significantly lower in the control group than in the TXA group at 6 hours, 1, 3, and 7 days after operation (P < 0.05). There was no significant difference in the hidden blood loss between 2 groups (t = 1.157, P = 0.252). The ratio of blood transfusion was significantly less in TXA group (6.7%, 4/60) than in control group (21.7%, 13/60)(P = 0.034). The total amount of blood transfusion was 14 units in TXA group, which was significantly less than that of control group (38 units) (P = 0.004). Deep vein thrombosis occurred in 3 cases in 2 groups respectively, showing no significant difference (P = 1.000). There was no symptomatic pulmonary embolism. All patients were followed up for 8-17 months, with an average of 13.7 months. No new VTE case was found during the follow-up period. CONCLUSION Intravenous injection of TXA (10 mg/kg) at 10 minutes before tourniquet release in TKA is effective in reducing perioperative blood loss, amount of blood transfusion, and ratio of transfusion, and it will not increase the risk of VTE.
