Total hip arthroplasty (THA) is a vital therapeutic tool for hip terminal disease. Frequently, hidden blood loss exists in the postoperation, which seriously affect the postoperative rehabilitation of patients. It is urgent need to solve the problem that how to fundamentally prevent and reduce hidden blood loss after THA. Although THA has its own operational reason in blood loss, and also relates to a variety of risk factors, the mechanism of hidden blood loss is not clear. Tranexamic acid has a significant role in preventing perioperative blood loss, and the correlation of hidden blood loss and fibrinolytic mechanism would be confirm necessarily in the future,which will produce positive significance in completing the mechanism of hidden blood loss.

How to remove the well fixed cement or cementless prosthesis and get a completely distal cement removal in the rTHR are critical to the outcome of revision. Because of higher rate of union, excellent intraoperative exposure, and adjustment of abductor tension, ETO has been widely applied to rTHR and complicated primary THR by foreign scholars. Furthermore, this technology has wide indications, very few contraindications, high cure rates,and low complications rate. ETO turns out to be a safe and effective revision technology. In the article, the indication, contraindication, complications and advantages of this technique were reviewed.

4.Guidelines for the diagnosis and treatment of prosthetic joint infection.
Chinese Journal of Surgery 2021;59(6):430-442
Prosthetic joint infection is one of the most serious complications after artificial joint replacement.Accurate diagnosis and proper standardized treatment are the keys to improve the cure rate of prosthetic joint infection,reduce the rate of recurrence and disability,and restore limb function.Regarding the diagnosis and treatment of prosthetic joint infection,although relevant research has progressed rapidly in recent years,there are still many problems that have not been well understood and explained,and there are still big differences and controversies in many aspects.This has brought a lot of confusion to clinicians during their daily practice.In order to make the diagnosis and treatment of prosthetic joint infection in China more standardized,a group of domestic experts in related fields was organized by the Joint Surgery Committee of the Chinese Orthopaedic Association to search the literature and integrate expert opinions,and compiled the "Guidelines for the diagnosis and treatment of prosthetic joint infection".Those most important and clinically concerned issues are elaborated,including the diagnostic criteria, standardized diagnostic algorithm,proper application of important tests,treatment principles,and the correct selection of various treatment options.Targeted and actionable recommendations are proposed.This guideline is expected to provide references for domestic colleagues in the diagnosis and treatment of prosthetic joint infection.

OBJECTIVETo evaluate the efficacy and safety of tourniquet in total knee arthroplasty.
METHODStudies on comparison between with and without tourniquet in total knee arthroplasty were identified from Medline, PubMed, EMASE, Cochrane Library, CBM, Highwire, CNKI, VIP, Articles Digital Periodicals.All the randomized controlled trials were included for meta-analysis with RevMan 4.2.2 software.
RESULTSNineteen studies involving 15 in foreign languages, 4 in Chinese were identified. There were 1159 cases of knee replacement patients. The results of meta-analysis indicated that there were statistical difference between two groups on intraoperative blood loss (P = 0.000), the number of deep venous thrombosis (P = 0.020), thigh pain (P = 0.000), knee hematoma (P = 0.030), wound infection (P = 0.040), skin ecchymosis area (P = 0.000), and the increasing rate of knee circumference of 3 days after the operation (P = 0.000), while there were no statistical differences with respect to the total blood loss (P = 0.100), the number of blood transfusions (P = 0.150), operation time (P = 0.120), length of hospital stay (P = 0.350), the number of pulmonary embolism (P = 0.310), and skin blisters (P = 0.170).
CONCLUSIONSThe tourniquet for total knee arthroplasty can reduce intraoperative blood loss, but can not reduce total blood loss and the number of blood transfusions transfusion, can not improve operative efficiency, can not shorten the hospitalization time and promote the knee joint functional recovery. Furthermore the tourniquet increases the probability of occurrence on deep vein thrombosis, wound infection, hematoma and ecchymosis knee, it also causes knee swelling and thigh pain. It suggests minimize to use tourniquet in total knee arthroplasty.

As an important indicator of total hip arthroplasty (THA) the rate and degree of offset reconstruction play an important role in improving the prognosis and life quality of patients. The reconstruction of femoral offset is closely related to reserved length of calcar femorale, the head and neck length of prosthesis, angle degree of neck shaft and whether lower limb is isometric. Reconstruction strategy includes making a meticulous and standard measurement before the surgery, predicting the reserved length of calcar femorale, selecting a prosthesis with approximate anatomical neck-shaft angle and reconstructing offset by adjusting the head and neck length of the prosthetic during the operation. The aim of this article was to introduce the research progress and influence of offset on hip function, prosthetic wear and postoperative complications such as pain, limp and unequal leg length, and to discuss the reconstruction strategy.

BACKGROUND:
Aspirin has demonstrated safety and efficacy for venous thromboembolism (VTE) prophylaxis following total hip arthroplasty (THA); however, inconsistent dose regimens have been reported in the literature. This study aimed to evaluate and compare the safety and efficacy of 100 mg aspirin twice daily with rivaroxaban in VTE prophylaxis following THA.
METHODS:
Patients undergoing elective unilateral primary THA between January 2019 and January 2020 were prospectively enrolled in the study and randomly allocated to receive 5 weeks of VTE prophylaxis with either oral enteric-coated aspirin (100 mg twice daily) or rivaroxaban (10 mg once daily). Medication safety and efficacy were comprehensively evaluated through symptomatic VTE incidence, deep vein thrombosis (DVT) on Doppler ultrasonography, total blood loss (TBL), laboratory bloodwork, Harris hip score (HHS), post-operative recovery, and the incidence of other complications.
RESULTS:
We included 70 patients in this study; 34 and 36 were allocated to receive aspirin and rivaroxaban prophylaxis, respectively. No cases of symptomatic VTE occurred in this study. The DVT rate on Doppler ultrasonography in the aspirin group was not significantly different from that in the rivaroxaban group (8.8% vs. 8.3%, χ2 = 0.01, P = 0.91), confirming the non-inferiority of aspirin for DVT prophylaxis (χ2 = 2.29, P = 0.01). The calculated TBL in the aspirin group (944.9 mL [658.5-1137.8 mL]) was similar to that in the rivaroxaban group (978.3 mL [747.4-1740.6mL]) (χ2 = 1.55, P = 0.12). However, there were no significant inter-group differences in HHS at post-operative day (POD) 30 (Aspirin: 81.0 [78.8-83.0], Rivaroxaban: 81.0 [79.3-83.0], χ2 = 0.43, P = 0.67) and POD 90 (Aspirin: 90.0 [89.0-92.0], Rivaroxaban: 91.5 [88.3-92.8], χ2 = 0.77, P = 0.44), the incidence of bleeding events (2.9% vs. 8.3%, χ2 = 0.96, P = 0.33), or gastrointestinal complications (2.9% vs. 5.6%, χ2 = 1.13, P = 0.29).
CONCLUSION:
In terms of safety and efficacy, the prophylactic use of 100 mg aspirin twice daily was not statistically different from that of rivaroxaban in preventing VTE and reducing the risk of blood loss following elective primary THA. This supports the use of aspirin chemoprophylaxis following THA as a less expensive and more widely available option for future THAs.

Objective Total knee arthroplasty is one of the most common orthopedic surgeries. Readmission due to severe complications after total knee arthroplasty is a grave concern to surgeons. In this study, we evaluated the risk factors for severe complications after primary total knee arthroplasty. Methods We retrospectively collected clinical data of 2,974 patients who underwent primary total knee arthroplasty from July 2013 to June 2019 in our hospital. Postoperative complication ≥ grade Ⅲ was defined as severe complication according to Clavien-Dindo classification system. Binary logistic regression was used to identify the predictive risk factors for severe complications. Results The complication rate after primary total knee arthroplasty was 6.8% and severe complication rate was 2.5%. Male (OR = 2.178, 95%CI: 1.324-3.585, P= 0.002), individuals above 75 years old (OR = 1.936, 95%CI: 1.155-3.244, P= 0.012), arrhythmia (OR = 2.913, 95%CI: 1.350-6.285, P= 0.006) and cerebrovascular disease (OR = 2.804, 95%CI: 1.432-5.489, P= 0.003) were predictive risk factors for severe complications after primary total knee arthroplasty. Conclusion Advanced age, male, arrhythmia, and cerebrovascular disease might be patients-related risk factors for postoperative severe complications after primary total knee arthroplasty. Special attention should be paid to patients with risk factors.
