RESUMO

BACKGROUND This meta-analysis was conducted to evaluate the clinical effectiveness and safety of Salvianolic acids for injection (SAFI) plus conventional treatment (CT) for patients with acute cerebral infarction (ACI) and to assess the evidence to guide clinical practice. MATERIAL AND METHODS PubMed, EMBASE, Cochrane Library, Web of Science, and 4 Chinese electronic databases were searched to identify relevant randomized controlled trials (RCTs). The methodological quality of eligible studies was evaluated using the Cochrane risk of bias tool. The reporting quality of eligible studies was evaluated by Consolidated Standards of Reporting Trials (CONSORT) for traditional Chinese medicine. Meta-analysis and evidence quality were performed using RevMan 5.3 and Grading of Recommendations Assessment, Development, and Evaluation (GRADE). RESULTS A total of 14 RCTs involving 1309 patients were included. Meta-analysis showed that SAFI plus CT was better than CT alone in improving the total effective rate (RR=1.35, 95% CI 1.25 to 1.44, P<0.00001), reducing the National Institutes of Health Stroke Scale (NIHSS) score (130 mg: WMD=-3.31, 95% CI -3.80 to -2.47, P<0.00001; 100 mg: WMD=-1.91, 95% CI -2.28 to -1.54, P<0.00001), improving the activity of daily living and cognitive function of ACI, and improving the hemorheology (HBV: high shear rate blood viscosity, LBV: low shear rate blood viscosity, PV: plasma viscosity) and C-reactive protein (CRP). CONCLUSIONS SAFI plus CT in the treatment of ACI can improve the total effective rate, neurological deficit, and ability to perform activities of daily living, and there is no serious adverse reaction. Based on the GRADE system, the evidence quality is low. More large-scale, well-designed, and high-quality RCTs are required to confirm the positive results.

RESUMO

Influenza virus A (IVA) is one of the predominant causative agents of the seasonal flu and has become an important cause of morbidity worldwide. Great efforts have been paid to develop vaccines against IVA. However, due to antigenic drift in influenza virus A and rapid emergence of drug­resistant strains, current available vaccines or anti­IVA chemotherapeutics are consistently inefficient. Hence, various more broadly effective drugs have become important for the prevention and treatment of IVA. Of these drugs, baicalin, a flavonoid isolated from Radix Scutellaria, is a promising example. However, little is known in regards to its pharmacological mechanism. Here, it was demonstrated that baicalin inhibits the H1N1 and H3N2 viruses in A549 cells. Subsequently, it was found that miR­146a was markedly downregulated by treatment of baicalin. Additionally, further experiments revealed that miR­146a was able to promote the replication of H1N1 and H3N2 by targeting TNF receptor­associated factor 6 (TRAF6), a pivotal adaptor in the interferon (IFN) production signaling pathway, to downregulate type I IFN production, and enrichment of miR­146a eliminated the anti­IVA effects of baicalin on the H1N1 and H3N2 viruses. Additionally, in vivo experiments demonstrated that baicalin could protect mice during H1N1 infection. Taken together, our findings firstly illustrated the anti­IVA molecular mechanism of baicalin and provide new evidence for targeting miRNAs to prevent and treat viral infection, such as the H1N1 and H3N2 viruses.

RESUMO

BACKGROUND: Low back pain is a common health problem worldwide, which also is a leading cause of long-term disability and has an important effect on the global economy and society. Usually, conservative therapies are used to treat low back pain. As a kind of Chinese patent medicine, Shujinjianyao pill (SJJYP) has a great curative effect on low back pain. However, its safety has not been studied yet. Therefore, we carried out this clinical trial to observe the safety of SJJYP in the real world. METHODS: First, participants need to meet the medication standards according to inclusion and exclusion criteria. Then, participants are conducted safety examination before taking SJJYP. After qualified screening, participants can be enrolled into the group. Second, all enrolled participants will receive SJJJYP for a period of 4 weeks. During the observation period, participants need to return to the hospital for a subsequent visit after 2 weeks of medication, and come to the hospital for safety check after 4 weeks of medication. Third, telephone follow-up is used to investigate any participants' physical discomfort after 6 to 8 weeks (2-4 weeks after medication withdrawal). After all these steps are completed, clinical observation is finished. If any adverse events occur during this process, we will record them in time. When serious adverse events occur, we will use nested case-control study to explore the causes and mechanisms. DISCUSSION: This study will obtain the safety results of SJJYP in clinical real world, which will offer a scientific basis for clinicians in the treatment of low back pain, and also provide a methodological basis for the safety study of other medicines. TRIAL REGISTRATION: ClinicalTrial.gov registration number is NCT03598153. This study was approved by the ethics committee of Wangjing hospital, China Academy of Chinese Medical Sciences (WJEC-KT-2018-012-P002).

RESUMO

BACKGROUND: Acute uncomplicated lower urinary tract infection (UTI) is one of the most common bacterial infections. Patients usually present with dysuria, urinary urgency, urinary frequency, and suprapubic pain or tenderness. Approximately 150 million people are diagnosed with UTI each year worldwide. The high recurrence rate of lower UTI is a common problem of clinical treatment. The misuse of antibiotics has led to the emergence of a number of resistant bacterial strains. Thus, traditional Chinese medicine is considered as an alternative option for treating acute uncomplicated lower UTI. Thus, this study aims to evaluate the efficacy and safety of Sanjin tablets (SJT) for the treatment of acute uncomplicated lower UTI, explore whether SJT can reduce or substitute the use of antibiotics, and reduce the recurrence rate in the treatment of acute uncomplicated lower UTI. METHODS/DESIGN: In this study, a randomized, double-blind, double-dummy, parallel control of positive drug, multicenter clinical study will be established. A total of 252 patients with acute uncomplicated lower UTI (syndrome of dampness-heat in the lower jiao) will be randomly allocated in the ratio of 1:1:1 to three groups: experimental group; control group 1; and control group 2. The experimental group receives Sanjin tablets plus levofloxacin tablets (LT) placebo; the control group 1 receives LT plus SJT placebo; and the control group 2 receives SJT plus LT on the first five days, SJT plus LT placebo on the last two days. Each group will be treated for seven days and followed-up 1-2 times. The primary outcome measures of effective rate and recurrence rate are symptoms. Secondary outcome measures of effective rate and recurrence rate are the urine leukocytes, bacteriology examination, and safety assessment. Outcomes will be assessed at baseline and after treatment. DISCUSSION: This study protocol will provide the research data of efficacy and safety of SJT for the treatment of acute uncomplicated lower UTI. The first aim is to determine whether Sanjin tablets can reduce the use of antibiotics; the second aim is to determine whether Sanjin tablets can substitute the use of antibiotics. The recurrence rate will be assessed after cured to determine whether SJT can reduce the recurrence rate. The results of this study will improve the rational use of drugs, especially the rational application of antibiotics. It will also enable safety evaluation from laboratory indices and adverse events, which will provide reliable evidence for clinical treatment. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03658291 .

RESUMO

Metabolic reprogramming plays an important role in supporting tumor growth. However, little is known about the metabolic alterations that promote cancer metastasis. In this study, we identify acyl-CoA thioesterase 12 (ACOT12) as a key player in hepatocellular carcinoma (HCC) metastasis. The expression of ACOT12 is significantly down-regulated in HCC tissues and is closely associated with HCC metastasis and poor survival of HCC patients. Gain- and loss-of-function studies demonstrate that ACOT12 suppresses HCC metastasis both in vitro and in vivo. Further mechanistic studies reveal that ACOT12 regulates the cellular acetyl-CoA levels and histone acetylation in HCC cells and that down-regulation of ACOT12 promotes HCC metastasis by epigenetically inducing TWIST2 expression and the promotion of epithelial-mesenchymal transition. Taken together, our findings link the alteration of acetyl-CoA with HCC metastasis and imply that ACOT12 could be a prognostic marker and a potential therapeutic target for combating HCC metastasis.

RESUMO

Altered metabolism is one of the hallmarks of cancer cells. Pentose phosphate pathway (PPP) is a fundamental component of cellular metabolism. Glucose-6-phosphate dehydrogenase (G6PD), the rate-limiting enzyme of the PPP, is elevated in many cancers and contributes to tumor growth by producing ribose-5-phosphate and NADPH through PPP. However, the role of G6PD in hepatocellular carcinoma (HCC) metastasis and the clinical significance of G6PD in HCC progression and prognosis have not been well determined. In this study, by investigating tissue samples from HCC patients and HCC cell lines, we found that elevated G6PD expression is significantly associated with HCC metastasis and poor prognosis of HCCs, and that knockdown of G6PD inhibits in vitro proliferation, migration and invasion of HCC cell lines. Further studies reveal that G6PD contributes to HCC migration and invasion of hepatocellular carcinoma cells by inducing epithelial-mesenchymal transition through activation of signal transducer and activator of transcription 3 (STAT3) pathway. Our findings suggest that targeting G6PD could open up possibilities for metastasis intervention and improve the patients' outcomes for HCC.

RESUMO

To analyze the drug combination characteristics of Qingkailing injection for treating abnormal inflammatory factors such as elevated white blood cells and C reactive protein in real world. The patients with Qingkailing injection for abnormal C reactive proteins and abnormal white blood cells were extracted from hospital information system (HIS) of 16 Class 3A hospitals. Then the basic information, traditional Chinese medicine and Western medicine diagnostic information, doctor's advice information, and laboratory information were analyzed; Apriori algorithm was used to construct the models, and Clementine 12.0 was used for correlation analysis to analyze the clinical medication rules and drug combination characteristics in the patients with Qingkailing injection for treatment of elevated C reactive protein and white blood cells in the real world. The results of the study showed that when Qingkailing injection was combined with one kind of western medicine and traditional Chinese medicine in treatment of patients with abnormal C reactive protein, vitamin C (159 cases, 74.30%) and Tanreqing injection (71 cases, 33.18%) were most frequently used; when it was combined with 2 kinds of traditional Chinese medicines, Xueshuantong injection plus Tanreqing injection (support degree 10.75%) were most frequently used. When Qingkailing injection was combined with one kind of western medicine and traditional Chinese medicine in treatment of patients with abnormal white blood cells, vitamin C (596 cases, 56.02%) and Ganmao Qingre granules (247 cases, 23.21%) were most frequently used; when it was combined with 2 kinds of traditional Chinese medicines, Shuanghuanglian+Ganmao Qingre granules (support degree 5.26%) were most frequently used. In the patients with abnormal C-reactive protein and white blood cells, its combinations with antibiotics and nutritional support agents were most common from the pharmacological perspective, indicating that in the treatment of abnormal C-reactive protein, white blood cells and other increased inflammatory indicators, Qingkailing injection was most frequently combined with antibiotic drugs to achieve synergistic effect.

RESUMO

To explore the clinical application features of Qingkailing injection for adolescent patients. This study was based on the information from the hospitalized patients in 1998-2011 in HIS (hospital information system) of 16 tertiary hospitals in China. 615 adolescent patients with Qingkailing injection were used to investigate the clinical characteristics of Qingkailing injection. Apriori algorithm was adopted to establish the model, and Clementine 12.0 was used for correlation analysis. The results showed that male patients (355 cases) were more than female patients (243 cases); the age of the most patients was under 14 years old, with an average age of 9.40 years old; the hospital stay was most of 4-7 d; the patients were mostly concentrated in pediatrics, mainly including upper respiratory tract infection; outpatient admission to the majority (451 cases, accounting for 75.54%). The traditional Chinese medicine (TCM) syndrome mainly included phlegm-dampness internal resistance (38.46%), Qi and Yin Deficiency (11.54%), Liver qi stagnation (15.38%), and Yang deficiency syndrome (11.54%); the highest admission rate was during Slight Cold (13.01%). In combined application, the most common western medicine pair was Cephalosporin injection+vitamin C (with supporting rate of 24.6%) and the most common TCM pair was Shuanghuanglian+Ganmao Qingre granules (with supporting rate of 4.065%). The most common 3 western medicines in combined use were Potassium chloride injection+Cephalosporin injection+vitamin C (supporting rate of 15.93%); while the most common three Chinese medicines were Shuanghuanglian+Yunnan Baiyao+Ganmao Qingre granules (supporting rate of 1.138%). Qingkailing injection was also widely used in adolescent patients; the diagnosis and use were basically in line with the instructions; men were slightly more than women; age of onset, solar terms and TCM syndromes were highly consistent. Qingkailing injection was mainly combined with western medicines in combined drug use, and Chinese medicines were also available. Combined drug use was more reasonable. Based on the results of the real world HIS, Qingkailing injection could provide the idea and reference for regulating the medication in adolescent patients.

RESUMO

BACKGROUND: The posterolateral (PL) graft experiences a high failure rate in anterior cruciate ligament double-bundle (DB) reconstruction. It is hypothesized that tunnel positions could dramatically affect the graft forces. METHODS: A validated computational model was used to simulate DB reconstruction with various femoral PL tunnel locations (8-11 mm center-center tunnel spacing). Graft fixation was simulated at both 0° and 30°. Knee biomechanics were examined with the knee under a 134 N anterior load and 400 N quadriceps load at 0°, 30°, 60°, and 90° of flexion. Graft forces, tibial translation, and tibial rotation were calculated. RESULTS: PL graft forces at full extension increased with increasing tunnel spacing under both fixation settings, but the knee kinematics was not dramatically affected. CONCLUSION: Small changes in the femoral PL tunnel position could result in large changes in graft forces, implying that precise PL tunnel position is an important factor in a successful DB reconstruction.

RESUMO

Objective To analyze clinical features and medication laws of patients with human immunodeficiency virus (HIV) infection. Methods Real world data based on Hospital Information System (HIS) were collected from 17 grade 3 hospitals across China from Jan.2006 to Dec.2011. Data of case his- tory in HIV infectors included their general information, features of AIDS, medications of Western drugs and Chinese herbs during hospitalization. Results Data of 451 patients with HIV infection were collected. A total of 261 patients had clear age record. Their age ranged between 18 and 65 [ accounting for 90. 4% (236/ 261 ) ], with an average age of 36. The ratio of male to female was 2. 8:1. They were hospitalized first at De- partment of Lemology (66. 96%), followed by Department of Respiration (8. 2%). They were admitted to hospital first at clinics (79. 6%), and accepted from Emergency Department (20. 18%). Most of them were admitted to hospital due to infectious diseases. Of them, tuberculosis occupied the top (8.29%), followed by bacterial pneumonia (6. 44%). Totally 349 patients had complete medication record. A total of 399 kinds of Western drugs and 80 kinds of Chinese patent medicines were used. The frequency of using antimicrobial drugs was the top (11. 86%), and Compound Sulfamethoxazole was mostly used in 120 cases (2. 81%). Of 80 kinds of Chinese patent medicines, heat clearing and detoxifying herbs were most often used (19. 27%), followed by antipyretics (10. 30%), tonics (8. 97%), and expectorant (7. 31%). Antimicrobial drugs combined heat clearing and detoxifying herbs were the most often seen in clinics. The 451 HIV infec- tors had steady condition after treated by Western drugs and Chinese herbs. The improvement rate reached 51. 33%. Conclusion Antimicrobial drugs were most often used in HIV patients. Heat clearing and detoxif- ying herbs were most often used in HIV patients. Antimicrobial drugs combined heat clearing and detoxif- ying herbs were most often seen in clinics for HIV patients.

RESUMO

This study was to investigate the in vivo tibiofemoral cartilage contact locations before and after anterior cruciate ligament (ACL) reconstruction at 6 and 36 months. Ten patients with unilateral ACL injury were included. A step-up motion was analyzed using a combined magnetic resonance modeling and dual fluoroscopic imaging techniques. The preoperative (i.e. ACL deficient and healthy contralateral) and postoperative cartilage contact locations at 6 and 36 months were analyzed. Similar patterns of the cartilage contact locations during the step-up motion were found for the preoperative and postoperative knee states as compared to the preoperative healthy contralateral side. At the end of step-up motion, the medial contact locations at postoperative 36 months were more anterior when compared to the preoperative healthy contralateral (p=0.02) and 6 months postoperative knee states (p=0.01). The changes of the cartilage contact locations at 36 months after ACL reconstruction compared to the healthy contralateral side were strongly correlated with the changes at 6 months postoperatively. This study showed that the tibiofemoral cartilage contact locations of the knee changes with time after ACL reconstruction, implying an ongoing recovery process within the 36 months after the surgery. There could be an association between the short-term (6 months) and longer-term (36 months) contact kinematics after ACL reconstruction. Future studies need to investigate the intrinsic relationship between knee kinematics at different times after ACL reconstruction.

RESUMO

The aim of this study is to examine and compare the similarities and differences between active components of S. miltiorrhiza depside salt and aspirin using perspective of pharmacological molecular networks. Active components of S. miltiorrhiza depside salt and aspirin's related genes were identified via the STITCH4.0 and GeneCards Database. A text search engine (Agilent Literature Search 2.71) and MCODE software were applied to construct network and divide modules, respectively. Finally, 32, 2, and 28 overlapping genes, modules, and pathways were identified between active components of S. miltiorrhiza depside salt and aspirin. A multidimensional framework of drug network showed that two networks reflected commonly in human aortic endothelial cells and atherosclerosis process. Aspirin plays a more important role in metabolism, such as the well-known AA metabolism pathway and other lipid or carbohydrate metabolism pathways. S. miltiorrhiza depside salt still plays a regulatory role in type II diabetes mellitus, insulin resistance, and adipocytokine signaling pathway. Therefore, this study suggests that aspirin combined with S. miltiorrhiza depside salt may be more efficient in treatment of CHD patients, especially those with diabetes mellitus or hyperlipidemia. Further clinical trials to confirm this hypothesis are still needed.

RESUMO

BRCA1 promoter methylation is an essential epigenetic transcriptional silencing mechanism, related to breast cancer (BC) occurrence and progression. We quantified the methylation level of BRCA1 promoter and evaluated its significance as prognostic and predictive factor. BRCA1 promoter methylation level was quantified by pyrosequencing in surgical cancerous and adjacent normal specimens from 154 BC patients. A follow up of 98 months was conducted to assess the correlation between BRCA1-methylation level vs. overall survival (OS) and disease free survival (DFS). The mean methylation level in BC tissues was significantly higher (mean 32.6%; median 31.9%) than in adjacent normal samples (mean 16.2%; median 13.0%) (P < 0.0001). Tumor stage (R = 0.6165, P < 0.0001) and size (R = 0.7328, P < 0.0001) were significantly correlated with the methylation level. Patients with unmethylated BRCA1 had a better OS and DFS compared to the methylated group (each P < 0.0001). BRCA1 promoter methylation level has a statistically significance on survival in BC patients (HazR = 1.465, P = 0.000) and is an independent prognostic factor for OS in BC patients (HazR = 2.042, P = 0.000). Patients with ductal type, HER2 negative, lymph node negative stage 1+2 tumors had a better OS and DFS. Classification of grades and molecular subtypes did not show any prognostic significance. Pyrosequencing is a precise and efficient method to quantify BRCA1 promoter methylation level, with a high potential for future clinical implication, as it identifies subgroups of patients with poorer prognosis.

RESUMO

In recent years, Chinese patent medicines such as smiltiorrhizadepsidesal(SMDS) injection are combined with western medicine to achieve good clinical efficacy for stable angina pectoris(SAP). SMDS is prepared by the water-soluble active ingredients extracted from Salvia miltiorrhiza, with the functions of promoting blood circulation, removing blood stasis and activating blood vessels, and it is used to treat type ⅠSAP and type ⅡSAP. The efficacy and safety of SMDS combined with simple routine western medicine for SAP were investigated by searching PubMed, EMbase, the Cochrane Library, CNKI, VIP, WanFang Data and CBM Database. SMDS combined with conventional western medicine treatment showed better efficacy for SAP as compared with western medicine alone, and better than other traditional Chinese medicines(such as Danshen injection and compound Danshen injection) combined with conventional western medicine. It was found that SMDS had a positive role in reducing blood viscosity, atherosclerosis, and improving microcirculation. The reported adverse drug reactions (ADRs) of SMDS combined with conventional western medicine therapy in clinical research were basically the same with ADRs reported by spontaneous reporting system(SRS) warning signals. Overall, SMDS combined with conventional western medicine had low incidence of ADR and no serious ADR occurred for SAP treatment in clinical trials. Currently, some drugs related to cardiovascular diseases such as ascinepazidemaleate injection, sodium succinate, propafenone hydrochloride and papaverine hydrochloride injection combined with SMDS have incompatibility, which should be highly emphasized in clinical use.

RESUMO

Prospective, multi-center, large-sample and registered design was used to analyze the drug combination features of Shenqi Fuzheng injection in the real world clinical application, and comprehend the drug combination in the real world. A total of 30 026 patients with the use of Shenqi Fuzheng injection were registered, where the chemical drugs were used for 57 436 times (accounting for 82.76%), and the Chinese patent medicines were used for 11 962 times (accounting for 17.24%), mainly including anti-acid drugs and anti-ulcer drugs, nutritional agent, immune enhancement agent, etc. According to the association rules, drug combinations of 2 drugs were closely related to inhibiting gastric acid secretion and anti-tumor; drug combinations of 3 drugs were closely related to inhibiting gastric acid secretion, antiemetic and anti tumor; drug combinations of 4 drugs were closely related to inhibiting gastric acid secretion, antiemetic, anti-tumor, and immune enhancement. The above results were consistent with the Instruction, providing clues for accurate treatment, and laying the foundation for clinical rational drug use.

RESUMO

Biomolecular network analysis was used to predict the mechanism of Salvianolate injection combined with aspirin for the treatment of stable angina pectoris(SAP). Related genes of Salvianolate injection, aspirin and SAP were obtained from Genecards, STITCH and DisGeNET databases. Agilent literature search software was used to construct biomolecular network; modules were identified by AP, MCODE and MCL methods. DAVID software was used for identification of related KEGG pathways. Results showed that Salvianolate injection and aspirin had a coverage rate of 45.92%, 62.56% respectively for SAP molecular network, and the coverage rate was 71.64% in combined use. The top 10 important nodes of SAP overlapped with Salvianolate injection and aspirin included MAPK14, MAPK8, IL-6 and IL-8. The important SAP nodes overlapped with Salvianolate injection alone included AKT1 and IFNG, and the important SAP nodes overlapped with aspirin included EPHB2 and TP53. Related SAP signaling pathways with combined Salvianolate injection and aspirin included Jak-STAT signaling pathway and MAPK signaling pathway. Related SAP signaling pathways with Salvianolate injection alone included VEGF signaling pathway and type 1 diabetes signaling pathway. Related SAP signaling pathways with aspirin alone included AA metabolism, linoleic acid metabolism signaling pathway, etc. The results showed that Salvianolate injection and aspirin combination had an enhancement effect in treatment of SAP through anti-inflammatory reaction and inhibition of atherosclerosis development; in addition, the combination use may have an additive effect through the antiplatelet aggregation, protecting endothelial cells, regulating blood lipid and regulating glucose metabolism.

OBJECTIVE: The expression of B-cell lymphoma 2 (Bcl-2) seems to be influenced by the endocrine environment. Numerous reports demonstrate the diverse expression of Bcl-2 family members under sex steroid regulation. With the exception of estrogen-related tumors, androgen-related tumors have shown their characteristics in Bcl-2 expression. In this study, the status of Bcl-2 expression in male hepatocellular carcinoma (HCC) patients was examined to verify the high incidence of HCC in males. METHODS: Tumor tissue microarray was used to examine Bcl-2 expression levels in 374 HCC cases including 306 males and 68 females. Kaplan-Meier method, log-rank test, and Cox proportional hazards model were applied to investigate the predictive value of Bcl-2 in HCC patients. RESULTS: Immunohistochemistry analysis showed that male patients with higher Bcl-2 levels had significantly longer median survival time and recurrence time than those with lower levels. However, no significant differences in outcomes were found between different Bcl-2 levels in female patients. When the male patients were stratified into several age points, the level of Bcl-2 expression showed poorer predictive efficiency in the 45-49 and 55-60 age groups in andropause-age patients compared with other age groups. Bcl-2 was an independent prognostic factor for both overall survival (P < 0.0001) and recurrence time (P = 0.0001) in male patients. After excluding male patients in the 45-60 age group, the predictive efficiency was enhanced (n = 147, OS, P = 0.0002, TTR, P < 0.0001). CONCLUSIONS: Bcl-2 expression is an independent predictor of survival and recurrence in male HCC. Bcl-2 levels may also be regulated by androgens or androgen receptors in male HCC patients. Bcl-2 levels change and exhibit poor predictive efficiency when androgen levels vary dramatically (andropause age).

RESUMO

BACKGROUND: Clinical outcome studies showed a high incidence of knee osteoarthritis after anterior cruciate ligament reconstruction. Abnormal joint kinematics and loading conditions were assumed as risking factors. However, little is known on cartilage contact forces after the surgery. METHODS: A validated computational model was used to simulate anatomic and transtibial single-bundle anterior cruciate ligament reconstructions. Two graft fixation angles (0° and 30°) were simulated for each reconstruction. Biomechanics of the knee was investigated in intact, anterior cruciate ligament deficient and reconstructed conditions when the knee was subjected to 134 N anterior load and 400 N quadriceps load at 0°, 30°, 60° and 90° of flexion. The tibial translation and rotation, graft forces, medial and lateral contact forces were calculated. FINDINGS: When the graft was fixed at 0°, the anatomic reconstruction resulted in slightly larger lateral contact force at 0° compared to the intact knee while the transtibial technique led to higher contact force at both 0° and 30° under the muscle load. When graft was fixed at 30°, the anatomic reconstruction overstrained the knee at 0° with larger contact forces, while the transtibial technique resulted in slightly larger contact forces at 30°. INTERPRETATION: This study suggests that neither the anatomic nor the transtibial reconstruction can consistently restore normal knee biomechanics at different flexion angles. The anatomic reconstruction may better restore anteroposterior stability and contact force with the graft fixed at 0°. The transtibial technique may better restore knee anteroposterior stability and articular contact force with the graft fixed at 30° of flexion.
