Clinical Characteristics and Treatment of Listeria monocytogenes Infections in the Central Nervous System.

Purpose: Listeria monocytogenes infections are rare in the central nervous system (CNS) and frequently difficult-to-diagnose. Our goal is to assess CNS listeriosis patients' clinical characteristics, diagnosis, treatment, and prognosis. Patients and Methods: Patients with CNS listeriosis admitted to the Department of neurology, the first medical center of the Chinese PLA general hospital, were enrolled in this study from March 2018 to August 2022. Results: This study analyzed eight adults, including five males and three females. The average age of onset was (50.25 ± 11.52) years. The clinical manifestations included fever, headache, altered mental status, vomiting, seizures, neck rigidity, hemiplegia and cranial nerve palsies. Cerebrospinal fluid (CSF) tests revealed intracranial hypertension, elevated cell count and protein concentration, and decreased glucose levels. The positive rates of blood and CSF culture were 40% and 28.57%, respectively. All patients underwent CSF metagenomic next-generation sequencing (mNGS), with a 100% positive rate and the specific read number 12-20394. Magnetic resonance imaging (MRI) exhibited leptomeningitis, meningoencephalitis, and brain abscess, and no specific changes were discovered in two patients. All patients received antibiotic treatment, seven were cured, and one died. Conclusion: Monitoring the proportion of monocytes in blood and mNGS results of CSF can play a crucial role in diagnosing pathogens. Early and sufficient application of two to three sensitive antibiotics with a BBB permeability of 20-30% for at least 2-3 months can significantly improve CNS listeriosis prognosis.

Spatial temporal feature of tuberculosis among high school students in Gansu Province from 2018 to 2022 / 中国学校卫生

Objective@#To analyze the spatial temporal distribution characteristics of tuberculosis among high school students at county levels in Gansu Province from 2018 to 2022,so as to provide a scientific basis for tuberculosis prevention and control in schools.@*Methods@#Tuberculosis data from high school students in counties (districts) reported in Gansu Province from 2018 to 2022 was collected from the Tuberculosis Information Management System and Infectious Disease Information Reporting System of the Chinese Disease Prevention and Control Information Management System. Demographic data of high school students in counties (districts) came from the General Management System of the Chinese Disease Prevention and Control Information Management System, and the spatial clustering of the reported incidence rate of pulmonary tuberculosis among high school students in Gansu Province in the past five years was analyzed using the methods of global spatial autocorrelation (Moran s I) and local indicators of spatial audocorrelation(LISA).@*Results@#A total of 41 885 pulmonary tuberculosis cases were reported in various counties of Gansu Province From 2018 to 2022, with an average reported incidence rate of 32.81/100 000. During the same period, 1 170 high school students cases were reported, with an average reported incidence rate of 13.72/100 000. With the exception of 2020, the reported incidence rate of pulmonary tuberculosis among high school students was non random distribution in other 4 years, showed a moderate intensity of spatial clustering. From 2018 to 2022, most counties in Gansu Province reported that the incidence rate of pulmonary tuberculosis among high school students was 10.00/100 000 or below, the counties with reported incidence rate >40.00/100 000 were mainly distributed in Luqu County, Maqu County, Diebu County, Hezuo City, Xiahe County of Gannan Prefecture, Gangu County and Wushan County of Tianshui Prefecture, Wenxian County and Kangxian County of Longnan Prefecture, Huachi County of Pingliang Prefecture, Huanxian County of Qingyang Prefecture. The number of counties where the reported incidence rate of tuberculosis among high school students more than 30.00/100 000 gradually decreased from 2018 to 2022. In the past five years, the reported incidence rate of tuberculosis among high school students in all counties of Gannan Prefecture remained above 40.00/ 100 000 . The LISA analysis results showed that the high incidence areas were mainly concentrated in Gannan Prefecture.@*Conclusions@#The epidemic situation of pulmonary tuberculosis among high school students in Gansu province from 2018 to 2022 is still a serious condition, showing the characteristics of unbalanced regional distribution. The reported incidence rate shows a strong spatial clustering, and the hot spots are concentrated in the counties (districts) of Gannan prefecture in Gansu Province.

Cognitive therapeutic exercise in early proprioception recovery after knee osteoarthritis surgery.

Objective: This research aims to explore the therapeutic effect of cognitive therapeutic exercise (CTE) in proprioception recovery after knee osteoarthritis (KOA) surgery. Methods: In total, thirty-seven patients recovering from KOA surgery (including 27 patients who had undergone high-tibial osteotomy (HTO) procedure and 10 patients who had received total knee arthroplasty (TKA) treatment were randomly assigned to two groups: 18 patients in the CTE group and 19 patients for the control group (non-CTE). Patients in the CTE group received proprioceptive training as cognitive therapy to facilitate proprioception recovery for up to 4 weeks: 5 days a week and two 10-min sessions a day. Except for cognitive therapeutic exercise, the NCTE group and CTE group had the same treatment protocols. All the interventions began with permission from the surgeon-in-charge. In this research, we applied the joint repositioning training or joint-matching tasks, which is part of the proprioceptive training as a measurement for a proprioceptive training result where patients moved their knee joint from 0° (completely straight knee joint) to produce a presented joint angle, such as 30, 60, and 90° of flexion. Joint-matching task results were recorded before the treatment, at 2 and 4 weeks, postoperatively. The absolute difference between the results of these exercises and the knee flexion angle targets will be measured at each test-pre-rehabilitation (Pre-Reha), 2 weeks post-rehabilitation (2 weeks post-Reha), and 4 weeks post-rehabilitation (4 weeks post-Reha). Results: The absolute difference in the CTE group was significantly smaller than that of the control group after 4 weeks of treatment (P < 0.05). After 2 weeks of cognitive therapeutic exercise, the absolute difference between patients' exercises of joint repositioning and the target angle of 30° in the CTE group was smaller than that of the NCTE group (P < 0.01). After 4 weeks of therapy, the joint position sense (JPS) among patients who received cognitive therapeutic exercise when performing joint repositioning at angles of 30 and 60° were better improved than those without receiving proprioceptive training with the absolute difference smaller than those of the control group (P < 0.05). Conclusion: The joint reposition training provided for the CTE group is a painless proprioceptive training practice. This method is simple and effective, making it easy for patients to understand the purpose of training and improve patient engagement. The research showed that after 4 weeks of rehabilitation and physical training, the proprioception sense of both the NCTE and CTE groups improved significantly, and the efficacy of proprioceptive training in the CTE group was better than that of the NCTE group, which provided a new approach to the early proprioception recovery of a patient with KOA after surgery.

Intermediate frequency electrotherapy stimulation to the medial femoris muscle for functional recovery of knee joint after anterior cruciate ligament reconstruction.

Objectives: To compare the effect of medial femoral muscle stimulation with medium frequency electrotherapy and conventional rehabilitation therapy on knee function recovery after anterior cruciate ligament (ACL) reconstruction. Methods: Medical records of 50 patients with ACL reconstruction, treated in our hospital between July 2019 and December 2020, were retrospectively analyzed. Patients were divided into control group and study group (n=25, 18 males and 7 females in each group), based on the rehabilitation method used. The control group included patients that received conventional rehabilitation therapy, active quadriceps femoris exercise, traction, and acupuncture. The study group included patients that received medium frequency electrotherapy to stimulate the medial femoris muscle in addition to conventional rehabilitation therapy. The limb circumference recorded before and after the treatment was compared between the two group. The Lysholm scores of the two groups were compared to assess knee function, knee range of motion, and knee motor comfort assessed by visual analogue scale (VAS). Results: We found similar thigh circumferences, Lysholm scores, knee motion ranges and VAS scores between the patients in both groups before the treatment (P > 0.05). After the treatment, the thigh circumferences and motion ranges were larger, the Lysholm scores higher, and the VAS scores lower in patients of the study group than those in patients of the control group (all Ps < 0.05). Conclusion: Intermediate frequency electrotherapy to stimulate the medial femoris muscle can improve knee function and motion range and reduce the patient's pain after ACL reconstruction.

Case Report: Diagnosis of Human Alveolar Echinococcosis via Next-Generation Sequencing Analysis.

Introduction: Alveolar echinococcosis (AE) is a rare parasitic disease caused by the infection of Echinococcus multilocularis. AE may mimic malignancy both in clinical presentation and radiological imaging, which is often misdiagnosed as metastatic tumor. Recently, next-generation sequencing (NGS) technologies are increasingly being used to address a diverse range of biological questions. Here, we describe a rare case of alveolar echinococcosis diagnosed by pan-pathogen screening, using next-generation sequencing. To the best of our knowledge, this is the first reported case of AE which was definitely diagnosed relying NGS of cerebrospinal fluid (CSF). Case Presentation: A 33-year-old man presented with repeat seizure and progressive headache for six months. Head magnetic resonance imaging (MRI) showed multiple masses with edema. Lung and abdominal computer tomography (CT) revealed multiple masses in bilateral lung, liver and the right adrenal gland. Bacterial, tuberculosis and fungal infection were excluded by CSF examination. Repeated target biopsy on the masses in the lung and liver showed as fibrous connective tissue without positive findings. NGS of CSF was performed and detected nucleic acid sequences of E. multilocularis. Consequently, the patient has accepted 1-year albendazole therapy. His case was followed up through imaging procedures. Conclusion: The next-generation sequencing of CSF is a reliable and sensitive diagnostic method for the detection of pathogenic microorganisms, and may allow the accurate diagnosis of alveolar echinococcosis. In view of this case, we recommend NGS as a potential tool for diagnosis of cerebral AE, especially if repeated biopsies are negative.

Metagenomic Next-Generation Sequencing of Cerebrospinal Fluid for the Diagnosis of Cerebral Aspergillosis.

Purpose: Cerebral aspergillosis (CA) is a rare but often fatal, difficult-to-diagnose, opportunistic infection. The utility of metagenomic next-generation sequencing (mNGS) for diagnosis of CA is unclear. We evaluated the usefulness of mNGS of the cerebrospinal fluid (CSF) for the diagnosis of CA. Methods: This prospective study involved seven consecutive patients with confirmed CA in whom CSF mNGS was performed. Serum (1→3)-ß-D-glucan and galactomannan levels were determined, and histopathological examination and mNGS of the CSF were conducted. CSF specimens from three non-infected patients were used as positive controls. Results: mNGS of the CSF was positive in six of the seven confirmed CA cases (85.71% sensitivity). In the cryptococcal meningitis group (control), mNGS of the CSF was positive for Aspergillus in two patients (84.62% specificity). The positive likelihood ratio, negative likelihood ratio, and Youden's index of mNGS for CA in the CSF were 5.565, 0.169, and 0.7, respectively. Among the six mNGS-positive cases, more than two Aspergillus species were found in four (4/6, 66.67%). In the positive controls, the addition of one A. fumigatus spore yielded a standardised species-specific read number (SDSSRN) of 25.45 by mNGS; the detection rate would be 0.98 if SDSSRN was 2. Conclusion: mNGS facilitates the diagnosis of CA and may reduce the need for cerebral biopsy in patients with suspected CA.

Central nervous system aspergillosis in immunocompetent patients: Case series and literature review.

The aim of this study was to investigate the clinical characteristics of central nervous system (CNS) aspergillosis in immunocompetent patients.This study enrolled six immunocompetent patients diagnosed with CNS aspergillosis. Additionally, we reviewed the clinical profiles for 28 cases reported in the literature. The age, gender, etiology of Aspergillus infection, clinical manifestations, location of the lesion, treatment, and prognosis were analyzed.There were 19 men (average age, 54.6 ±â€Š14.3 years) and 15 women (average age, 47.0 ±â€Š19.4 years). The clinical manifestations included headache (55.9%; n = 19), visual impairment (32.4%; n = 11), diplopia (32.4%; n = 11), hemiplegia (20.6%; n = 7), fever (17.6%; n = 6), and epilepsy (8.8%; n = 3). According to the radiological features, CNS aspergillosis lesions were divided into two subtypes: parenchymal lesions in the cerebral lobes (n = 11), and meningeal lesions in the meninges (n = 23). The patients with meningeal lesions are easy to be complicated with more serious cerebrovascular diseases, such as subarachnoid hemorrhage and massive infarction. Most of the lesions in brain parenchyma were abscess formation, and magnetic resonance imaging showed ring enhancement. The clinical diagnosis of Aspergillus infection was mainly based on brain biopsy (n = 14), autopsy (n = 8), pathological examination of adjacent brain tissues (n = 7), cerebrospinal fluid (CSF) or tissue culture (n = 3), and second-generation sequencing analysis of the CSF (n = 3). Clinical improvement was achieved in 23 cases, and 11 patients succumbed to the disease. Voriconazole treatment was effective in 24 (70.6%) cases.Immunocompetent subjects are also at risk for Aspergillus infections. Concomitant cerebrovascular diseases are common in patients with CNS aspergillosis, especially in patients with meningeal aspergillosis. Parenchymal aspergillosis lesions are usually localized and manifest as brain abscesses with annular enhancement on magnetic resonance imaging. Biopsy, CSF culture, and next-generation sequencing are mainstream diagnostic modalities. Voriconazole is an effective treatment for Aspergillus infection, and early diagnosis and treatment should be highlighted.

Metagenomic Next-Generation Sequencing for Diagnosis of Infectious Encephalitis and Meningitis: A Large, Prospective Case Series of 213 Patients.

Purpose: We assessed the performance of metagenomic next-generation sequencing (mNGS) in the diagnosis of infectious encephalitis and meningitis. Methods: This was a prospective multicenter study. Cerebrospinal fluid samples from patients with viral encephalitis and/or meningitis, tuberculous meningitis, bacterial meningitis, fungal meningitis, and non-central nervous system (CNS) infections were subjected to mNGS. Results: In total, 213 patients with infectious and non-infectious CNS diseases were finally enrolled from November 2016 to May 2019; the mNGS-positive detection rate of definite CNS infections was 57.0%. At a species-specific read number (SSRN) ≥2, mNGS performance in the diagnosis of definite viral encephalitis and/or meningitis was optimal (area under the curve [AUC] = 0.659, 95% confidence interval [CI] = 0.566-0.751); the positivity rate was 42.6%. At a genus-specific read number ≥1, mNGS performance in the diagnosis of tuberculous meningitis (definite or probable) was optimal (AUC=0.619, 95% CI=0.516-0.721); the positivity rate was 27.3%. At SSRNs ≥5 or 10, the diagnostic performance was optimal for definite bacterial meningitis (AUC=0.846, 95% CI = 0.711-0.981); the sensitivity was 73.3%. The sensitivities of mNGS (at SSRN ≥2) in the diagnosis of cryptococcal meningitis and cerebral aspergillosis were 76.92 and 80%, respectively. Conclusion: mNGS of cerebrospinal fluid effectively identifies pathogens causing infectious CNS diseases. mNGS should be used in conjunction with conventional microbiological testing.

Brain Atrophy Associated with Primary Diffuse Meningeal Melanomatosis.

BACKGROUND: Primary meningeal melanomatosis is a rare leptomeningeal tumor, and the diagnosis is challenging due to nonspecific clinical symptoms and radiologic findings. CASE DESCRIPTION: A 21-year-old man presented with recurrent seizure and impaired memory. Cranial magnetic resonance imaging showed obvious brain atrophy with bilateral extensive meningeal enhancement in the supratentorial region. Diffusion-weighted imaging and fluid-attenuated inversion recovery showed slightly hyperintensive signals in the cortex. Microscopic examination revealed invasion of pigment into the Virchow-Robin space and cortex. Immunohistochemical examination of biopsy samples showed that cells were immunopositive for HMB45 and S-100 and immunonegative for melan-A with a Ki-67-positive percentage of 3%. No obvious atypia or nuclear mitosis was observed. Pathohistologic results of biopsied meninges confirmed the diagnosis of diffuse meningeal melanomatosis. The disease was aggravated with the occurrence of brain atrophy, recurrent seizure, and declined higher cortical function. CONCLUSIONS: This case report illustrates that brain atrophy in meningeal melanomatosis is associated with a progressive decline of higher cortical function.

Apparent performance of metagenomic next-generation sequencing in the diagnosis of cryptococcal meningitis: a descriptive study.

INTRODUCTION: In recent years, metagenomic next-generation sequencing (mNGS) has become widely used in medical microbiology to detect pathogen infection. AIM: We aimed to assess the diagnostic performance of mNGS of cerebrospinal fluid (CSF) for prediction of cryptococcal meningitis (CM). METHODOLOGY: A comparative evaluation of mNGS (performed on CSF samples) and conventional methods, including India ink staining, culture for fungi and cryptococcal-antigen (CrAg) detection by enzyme immunoassay, was performed on 12 consecutive non-HIV-infected patients with chronic or subacute CM. RESULTS: India ink staining and culture of the CSF were positive for Cryptococcus in 83.33 % (10/12) of the samples; 100 % (11/11) were positive via CrAg EIA. The mNGS results of the CSF identified DNA sequences corresponding to Cryptococcus in 75 % of samples (9/12). However, the DNA of both C. neoformans s.l. and C. gattii s.l. was detected concurrently in 33.33 % (4/12). CONCLUSION: mNGS is helpful for identifying Cryptococcus species. The application of mNGS, together with India ink staining, culture methods, and CrAg, may significantly improve the diagnostic precision in CM, thereby informing choice of appropriate antifungal treatment courses.

Liver Enzymes, Fatty Liver and Type 2 Diabetes Mellitus in a Jinchang Cohort: A Prospective Study in Adults.

OBJECTIVES: It is unclear whether liver enzymes or the interactions of various liver enzymes is a predictor of type 2 diabetes mellitus (T2DM), which is independent of fatty liver. METHODS: A total of 48,001 subjects participated in baseline examinations. Among the subjects, 33,355 were followed for an average of 2.2 years. Cox proportional hazard models were used to examine the adjusted associations of AST, GGT and ALT with T2DM. RESULTS: The cumulative incidence of T2DM was 8.05% to 9.02% for fatty liver and 2.25% to 4.10% for non-fatty liver, both showing statistically significant differences. Compared with the normal liver enzyme levels in the group with fatty liver, the adjusted incident hazard ratios in T2DM were: ALT 1.23 (95% CI 1.10 to 1.50); AST 1.30 (95% CI 1.07-1.59); and GGT 1.34 (95% CI 1.08 to 1.65). In addition, compared with the normal liver enzyme levels in the group with non-fatty liver, the adjusted incident hazard ratios in type 2 diabetes were: ALT 1.27 (95% CI 1.02 to 1.59); AST 1.33 (95% CI 1.02 to 1.59); and GGT 1.53 (95% CI 1.19 to 1.98). There are significant interactions of T2DM hazard ratios between GGT and ALT and between GGT and AST in addition to ALT and AST. CONCLUSIONS: Our results suggest that the incidence of T2DM in the group with fatty liver is significantly higher than that in the normal population, and the rise of serum AST, GGT and ALT levels are risk factors independent of fatty liver for the development of T2DM after adjusting for confounding factors.

Evaluation of Next-Generation Sequencing for the Diagnosis of Infections of the Central Nervous System Caused by the Neurotropic Herpes Viruses: A Pilot Study.

BACKGROUND: There are sparse and limited studies on small sample size reporting the application of next-generation sequencing (NGS) in the detection of central nervous system (CNS) viral infections. We assessed the diagnostic performance of NGS of cerebrospinal fluid (CSF) for predicting viral infections of the CNS caused by the neurotropic herpes viruses in a pilot population. MATERIALS AND METHODS: We prospectively collected CSF samples from 24 patients with CNS viral infection from April 2017 to October 2018. Of the 24 patients, 19 patients were infected with herpes simplex virus 1 (HSV-1), 1 patient with HSV-2, and 4 patients with varicella-zoster virus (VZV). All CSF samples were screened for viral DNA using NGS technologies to detect viral CNS infections. RESULTS: Of the 24 patients with confirmed viral CNS infection caused by the neurotropic herpes viruses, 10 (10/24, 41.67%) patients exhibited positive NGS results. With the help of NGS, HSV-1 DNA was detected in the CSF of 6 patients (6/19; 31.58%). HSV-2 DNA was detected in 1 patient (1/1; 100%) and VZV DNA was detected in 3 patients (3/4; 75%). The positive rate of virus detected by NGS decreased with time. The positive rates of NGS of CSF in the first, second, and third weeks were 54.5% (6/11), 44.4% (4/9), and 0% (0/4), respectively. CONCLUSIONS: NGS method is a promising pathogen detection tool for identifying viral CNS infections. It should be recommended to sequence viral DNA of CSF in the early stage of CNS viral infections.

Effectiveness of Screening Modalities in Colorectal Cancer: A Network Meta-Analysis.

The aim of the study was to evaluate on the effectiveness of screening modalities in the prevention of colorectal cancer (CRC) occurrence and deaths. General meta-analysis was performed to produce pooled estimates of the effect of CRC incidence and mortality using a search of PubMed, Web of Science, and the Cochrane Library for eligible studies from January 1992 to March 2016. A network meta-analysis was performed to synthetically compare the effectiveness of 5 frequently used screening modalities. A total of 44 studies with a focus on mortality from CRC using different screening methods were included. General meta-analysis showed that fecal immunohistochemical testing (FIT), flexible sigmoidoscopy (FS), colonoscopy, combination of fecal occult blood testing and FS screening respectively reduced CRC mortality by 59% (relative risk [RR], 0.41; 95% confidence interval [CI], 0.29-0.59), 33% (RR, 0.67; 95% CI, 0.58-0.78), 61% (RR, 0.39; 95% CI, 0.31-0.50), 38% (RR, 0.62; 95% CI, 0.42-0.91) compared with no screening, whereas guaiac fecal occult blood testing (gFOBT) reduced CRC-related mortality by 14% (RR, 0.86; 95% CI, 0.82-0.90). Subgroup analysis showed that summary estimates of reduction in distal CRC mortality and proximal CRC mortality were 26% (95% CI, 62%-89%) and 10% (95% CI, 83%-98%). A network meta-analysis revealed rank probability analysis in which the colonoscopy had a 94.6% probability of being the most effective examination to reduce CRC mortality. In addition, the network meta-analysis estimated odds ratio, which was a 79% reduction (95% CI, 0.09-0.60) in CRC mortality when screening with FIT was compared with annual or biennial gFOBT and colonoscopy was approximately 80% more effective than gFOBT for reducing CRC mortality (RR, 0.25; 95% CI, 0.13-0.54). Analysis of the effects of different screening methods showed that there was a significant reduction in the incidence of colon cancer, excluding gFOBT. This meta-analysis confirmed that gFOBT, FIT, FS, and colonoscopy were all effective in preventing CRC deaths and a major reduction in distal but not proximal CRC mortality was found. In addition, they were more effective in preventing CRC incidence in addition to gFOBT. The network meta-analysis suggests that colonoscopy is the most effective screening for preventing CRC deaths.

Leukoencephalopathy with calcifications and cysts: A case report.

RATIONALE: Leukoencephalopathy with calcifications and cysts (LCC) is an uncommon entity characterized by edematous leukoencephalopathy, cerebral calcifications, and parenchymal cysts. Due to its rarity, the clinical, radiological, and histopathological features have yet to be well elucidated. PATIENT CONCERNS: The first case is a 35-year-old female who was asymptomatic. A giant intracranial cyst was incidentally detected radiologically, and it was slowly growing in the recent 10 years. The second case is a 20-year-old female who presented with a 1-month history of headache. Brain computed tomography showed multiple asymmetric calcifications in the bilateral basal ganglia and white matter. Magnetic resonance imaging revealed a cyst in the right parietal lobe. DIAGNOSES: They were diagnosed with LCC. INTERVENTIONS AND OUTCOMES: The first patient underwent surgical resection of the intracranial cyst, and the second patient received a stereotactic biopsy. The patients performed well postoperatively. LESSONS: LCC can be found at any age. A young age seems to be associated with severer symptoms. The clinical manifestations can be variable and aggressive. The potential pathogenic basis still needs further research.

Balance ability and proprioception after single-bundle, single-bundle augmentation, and double-bundle ACL reconstruction.

PURPOSE: The present study sought to determine the influences of single-bundle (SB), single-bundle augmentation (SBA), and double-bundle (DB) reconstructions on balance ability and proprioceptive function. METHODS: 67 patients who underwent a single- or double-bundle ACL reconstruction or a SBA using multistranded autologous hamstring tendons were included in this study with a 1-year follow-up. Body sway and knee kinesthesia (using the threshold to detect passive motion test (TTDPM)) were measured to indicate balance ability and proprioceptive function, respectively. Additionally, within-subject differences in anterior-posterior stability of the tibia and lower extremity muscle strength were evaluated before and after surgery. RESULTS: At 6 and 12 months after surgery, DB reconstruction resulted in better balance and proprioceptive function than SB reconstruction (P < 0.05). Although no significant difference was observed in balance ability or proprioceptive function between the SBA and DB reconstructions, knee stability was significantly better with SBA and DB reconstructions than SB reconstruction (P < 0.05). No significant differences were found in quadriceps and hamstrings strength among the three reconstruction techniques. CONCLUSIONS: Our findings consider that joint stability, proprioceptive function, and balance ability were superior with SBA and DB reconstructions compared to SB reconstruction at 6 and 12 months after surgery.
