EFORT open reviews. 2024;9(1):80-91
Abstract
PURPOSE Tourniquets are commonly used intraoperatively in orthopaedic surgery to control bleeding and improve visibility in the surgical field. Recent evidence has thrown into question the routine use of tourniquets in the adult population resulting in a British Orthopaedic Association standard for intraoperative use. This systematic review evaluates the evidence on the practice, benefits, and risks of the intraoperative use of tourniquets for trauma and elective orthopaedic surgery in the paediatric population. METHODS A prospectively registered systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO CRD42022359048). A search of MEDLINE, Embase, the Cochrane Library and a Grey literature search was performed from their earliest record to 23 March 2023. Studies reporting tourniquet data in paediatric patients undergoing orthopaedic surgery were included. Data extracted included demographics, involved limb, trauma versus elective use, tourniquet use as primary or secondary measure, and tourniquet parameters and complications. RESULTS Thirty-nine studies were included. Tourniquet practices and information reporting varied considerably. Tourniquets were used uneventfully in the majority of patients with no specific benefits reported. Several physiological and biochemical changes as well as complications including nerve injury, compartment syndrome, skin burns, thrombosis, post-operative limb swelling, and pain were reported. CONCLUSIONS Tourniquets are routinely used in both trauma and elective paediatric orthopaedic surgery with no high-quality research affirming benefits. Severe complications associated with their use are rare but do occur. High-quality studies addressing their benefits, the exact indication in children, and the safest way to use them in this population are necessary.

Effect of bone marrow aspiration concentrate and platelet-rich plasma combination in anterior cruciate ligament reconstruction: a randomized, prospective, double-blinded study
Lin, Y. C., Chen, Y. J., Fan, T. Y., Chou, P. H., Lu, C. C.
Journal of orthopaedic surgery and research. 2024;19(1):4
Abstract
BACKGROUND The effect of bone marrow aspirate concentrate (BMAC) and platelet-rich plasma (PRP) combination in enhancing graft maturation and tendon-bone tunnel interfacial healing after anterior cruciate ligament (ACL) reconstruction remains unclear. We hypothesised that BMAC and PRP combination could lead to better clinical results and better graft maturation/interface healing than PRP alone or conventional ACL reconstruction without any other biologic augmentation. METHODS In this randomised double-blind prospective study, patients undergoing ACL reconstruction surgery were randomly assigned into three groups: (1) control group (without any biologic augmentation), (2) PRP treatment group, and (3) combined BMAC and PRP (BMAC + PRP) group. Moreover, they were evaluated using the clinical functional score, laxity examination, and magnetic resonance imaging (MRI) analysis. RESULTS No significant difference was observed in the improvement of functional scores among groups. However, laxity improvement at 24 weeks showed a significant difference with the BMAC + PRP group having the lowest laxity. MRI analysis showed no significant change in whole graft maturation among groups. In particular, the BMAC + PRP group showed delayed signal peak and higher graft signal at 24 weeks compared with the other two groups; however, the difference was not significant. With regard to tendon-bone interfacial healing, the BMAC + PRP group showed significantly wider tendon-bone interface in the femoral bone tunnel at 24 weeks compared with the other two groups. Moreover, the BMAC + PRP group showed significantly higher peri-tunnel edema signal in the femoral bone tunnel at 12 weeks compared with the other two groups. CONCLUSION PRP alone and BMAC and PRP combination showed limited enhancing effect in clinical function, graft maturation and tendon-bone interfacial healing compared with control (no additional treatment). When BMAC is used in ACL reconstruction, the possibility of greater inflammation in the early stage to graft maturation and bone tunnel healing should be considered.

Journal of Orthopaedic Surgery and Research. 2023;18(1):178
Abstract
BACKGROUND This randomized controlled study was undertaken to investigate the efficacy of intravenous tranexamic acid (TXA) administration in reducing perioperative blood loss in patients undergoing medial opening-wedge distal tibial tuberosity osteotomy (MOWDTO). It was hypothesized that TXA would reduce perioperative blood loss in MOWDTO. METHODS A total of 61 knees in 59 patients who underwent MOWDTO during the study period were randomly assigned to either of the groups with intravenous TXA administration (TXA group) or without TXA administration (control group). In the TXA group, patients received 1000 mg of TXA intravenously before skin incision and 6 h after the first dose. The primary outcomes was the volume of perioperative total blood loss which calculated using the blood volume and hemoglobin (Hb) drop. The Hb drop was calculated as the difference between preoperative Hb and postoperative Hb at days 1, 3, and 7. RESULTS The perioperative total blood loss was significantly lower in the TXA group (543 ± 219 ml vs. 880 ± 268 ml, P < 0.001). The Hb drop was significantly lower at postoperative days 1, 3 and 7 in the TXA group than in the control group (day 1: 1.28 ± 0.68 g/dl vs. 1.91 ± 0.69 g/dl, P = 0.001; day 3: 1.54 ± 0.66 g/dl vs. 2.69 ± 1.00 g/dl, P < 0.001; day 7: 1.74 ± 0.66 g/dl vs. 2.83 ± 0.91 g/dl, P < 0.001). CONCLUSION Intravenous TXA administration in MOWDTO could reduce the perioperative blood loss. Trial registration The study was approved by the institutional review board.

Kansas journal of medicine. 2023;16:302-308
Abstract
INTRODUCTION Tranexamic acid (TXA) use has become common in orthopedic surgeries. Despite the growing number of publications related to its use, no recent systematic reviews have been published examining TXA use in foot and ankle surgery. The purpose of this review article is to provide a summary of the current available literature regarding TXA use in foot and ankle surgery and to further the understanding of its safety and efficacy. METHODS This systematic review utilized PubMed, Ovid, CINAHL, Clinical Key, Medline, and Embase, and the search was conducted through December 22, 2022. Key words used in the search included: "tranexamic acid," "TXA," "foot," "ankle," "calcaneal," and "surgery." The outcomes within the studies analyzed included measures of perioperative blood loss (intra-operative blood loss, 24-hour post-operative blood loss, blood loss from hour 24 to hour 48, post-operative hemoglobin (Hgb), and post-operative hematocrit [Hct]), as well as wound complications and vascular events. Meta-regression was included to assess the impact of age on between-study variation. RESULTS Ten studies met preliminary inclusion criteria. Upon further inspection, eight met full inclusion criteria for the meta-analysis. Despite a growing amount of literature on the topic, there is still a paucity of literature published on TXA use in foot and ankle surgery. Current literature suggests that foot and ankle surgery patients treated with TXA may have reduced 24-hour post-operative blood loss (MD=-183.41 mL, 95% CI=-247.49 to -119.34 mL, p<0.001), increased post-operative hemoglobin (MD=0.71 g/dL, 95% CI=0.11 to 1.31 g/dL, p=0.020) and hematocrit (MD=2.66%, 95% CI=0.07 to 5.24%, p=0.040) when compared to similar patients not receiving TXA. The use of TXA in foot and ankle surgery did not lead to increased thromboembolic complications. Meta-regression indicated no clinically relevant association of age to between-study variation. CONCLUSIONS TXA was found to be a safe treatment that did affect wound healing or infection rates while decreasing perioperative blood loss. Further research should be performed to evaluate the long-term effects of TXA administration on patient outcomes after foot and ankle surgery.

Abstract
BACKGROUND Total knee arthroplasty (TKA) is associated with significant blood loss and postoperative transfusion. The accelerometer-based navigation (ABN) system guides the bone cutting plane without breaching the intramedullary canal, which may reduce bleeding. This study aimed to investigate blood loss and transfusion compared between the ABN system and the conventional procedure in patients undergoing one-stage sequential bilateral TKA (SBTKA). METHODS A total of 66 patients scheduled for SBTKA were randomly allocated to either the ABN or conventional group. Postoperative hematocrit (Hct) level, drainage blood loss, transfusion rate, and amount of packed red cell transfusion were collected. Total red blood cell (RBC) loss was then calculated for the primary outcome. RESULTS The mean calculated total RBC loss in the ABN and conventional group was 669.7 and 630.0 mL, respectively (p = 0.572). There was no significant difference between groups for other evaluated outcome parameters, including postoperative Hct level, drainage blood loss, or packed red cell transfusion volume. All patients in the conventional group required postoperative blood transfusion while 96.8% of patients in the ABN group were transfused. CONCLUSIONS The total RBC loss and volume of packed red cells transfusion were not significant difference between interventions, which suggest no benefit of the ABN system in reducing blood loss and transfusion in patients undergoing SBTKA. TRIAL REGISTRATION The protocol of this study was registered in the Thai Clinical Trials Registry database no. TCTR20201126002 on 26/11/2020.

JB & JS open access. 2023;8(4)
Abstract
BACKGROUND Tourniquet application in total knee arthroplasty (TKA) has many benefits and may have a role in the incidence of perioperative complications. Our aims were to examine the safety of applying a tourniquet for a limited amount of time during primary unilateral TKA (specifically, during cementation and final component fixation only) and to compare perioperative complications between the limited-application group and the full-application group. METHODS We conducted a randomized controlled study of 62 patients undergoing primary unilateral TKA. Patients were randomly allocated to either the limited or full tourniquet application. The follow-up period was 6 months. We evaluated intraoperative, postoperative, total, and hidden blood loss as the primary outcome measures and clearance of the surgical field, operative duration, and perioperative complications as the secondary outcome measures. RESULTS We found a significant difference in surgical field clearance between the groups. There was no significant difference in total, hidden, or postoperative blood loss between the groups. Mean intraoperative blood loss was significantly lower in the full-application group than in the limited-application group (171.742 ± 19.710 versus 226.258 ± 50.290 mL; p = 0.001). Perioperative complications, including allogeneic blood transfusion rates, did not significantly differ between the groups. CONCLUSIONS Limited tourniquet application is safe to use in primary unilateral TKA and does not increase the incidence of perioperative complications or total blood loss when compared with a standard, full-time tourniquet application.

Abstract
BACKGROUND The objectives of the researchers are as follows: First, to investigate whether intraoperative or postoperative administration of Intravenous (IV) iron supplements in patients undergoing primary total knee arthroplasty (TKA) can contribute to the hemoglobin recovery during the postoperative period (between 4 and 8 weeks after surgery). Second, to examine whether the administration of IV iron supplements during or immediately after TKA in patients undergoing primary TKA can reduce the need for allogenic blood transfusion during hospitalization. METHODS Articles published between January 1, 1990, and June 30, 2023 were searched in PubMed, Cochrane, and Embase. The population, intervention, comparison, and outcome of this study are as follows; Population: Patients undergoing primary total knee arthroplasty; Intervention: Administration of IV iron supplements during or immediately after surgery; Comparison: Non-administration of IV iron supplements; Outcome: Degree of hemoglobin recovery (between 4 and 8 weeks after surgery) and the need for blood transfusion during hospitalization. RESULTS There was a statistically significant difference in the amount of change in hemoglobin between iron supplementation group and non-iron supplementation group. The effect size were -0.44 (95% confidence interval: -0.69 to -0.19, P value < .001) in all patients. This means that the amount of change in hemoglobin were significantly reduced in the iron supplementation group than in the non-iron supplementation group. There was a statistically significant difference for post-operative transfusion rate between 2 groups. The effect size were 0.28 (95% confidence interval: 0.10-0.81, P value = .02) in all patients. This means that the post-operative transfusion rate was significantly less in the iron supplementation group than in the non-iron supplementation group. CONCLUSION The administration of IV iron supplements during or after TKA surgery increases hemoglobin recovery between 4 and 8 weeks after surgery and reduces the need for allogeneic blood transfusion during hospitalization.

Xiao C, Gao Z, Yu W, Yao K, Cao Y, Long N, Zhang S, Jiang Y
International orthopaedics. 2023
Abstract
PURPOSE Studies have shown an average postoperative hidden blood loss (HBL) of 473.29 ml and an average Hb loss of 16.71 g/l after intramedullary nailing. Reducing HBL has become a primary consideration for orthopaedic surgeons. METHODS Patients with only tibial stem fractures who visited the study clinic between December 2019 and February 2022 were randomized into two groups using a computer-generated form. Two grams of tranexamic acid (TXA) (20 ml) or 20 ml of saline was injected into the medullary cavity before implantation of the intramedullary nail. On the morning of the surgery, as well as on days one, three and five after surgery, routine blood tests and analyses of CRP and interleukin-6 were completed. The primary outcomes were total blood loss (TBL), HBL, and blood transfusion, in which the TBL and HBL were calculated according to the Gross equation and the Nadler equation. Three months after surgery, the incidence of wound complications and thrombotic events, including deep vein thrombosis and pulmonary embolism, was recorded. RESULTS Ninety-seven patients (47 in the TXA group and 50 in the NS group) were analyzed; the TBL (252.10 ± 10.05 ml) and HBL (202.67 ± 11.86 ml) in the TXA group were significantly lower than the TBL (417.03 ± 14.60 ml) and HBL (373.85 ± 23.70 ml) in the NS group (p < 0.05). At the three month postoperative follow-up, two patients (4.25%) in the TXA group and three patients (6.00%) in the NS group developed deep vein thrombosis, with no significant difference in the incidence of thrombotic complications (p = 0.944). No postoperative deaths or wound complications occurred in either group. CONCLUSIONS The combination of intravenous and topical TXA reduces blood loss after intramedullary nailing of tibial fractures without increasing the incidence of thrombotic events.

Dorsal Wrist Ganglion: Pilot for Randomized Control Trial Comparing Aspiration Alone or Combined with Injection of Platelet-Rich Plasma
Hamlin K, Haddon A, Khan Y, Miller C, Lawrie D
Journal of wrist surgery. 2023;12(1):18-22
Abstract
This pilot study assessed the feasibility of performing a randomized control trial (RCT) investigating injection with platelet-rich plasma (PRP) for dorsal wrist ganglion (DWG). Aspiration alone was compared with aspiration plus injection of PRP. Seventeen patients were enrolled. Nine patients received PRP and eight aspiration alone. Patients were followed up at 6 weeks and 1 year; recurrence of the ganglion and Patient Evaluation Measure scores were measured. At 6 weeks seven patients in the aspiration group had a recurrence and five in the PRP group, but by 1 year, this has increased to seven out of eight in the PRP group whereas in the aspiration group four had resolved leaving three out of eight patients with a ganglion still present. From the basis of our work an RCT would require a minimum of 46 patients per group; however, it is unlikely that PRP will be a panacea for ganglia. This is a Level II study.
