Mycobacterium tuberculosis infection has emerged as a global public health issue, predominantly manifesting as pulmonary tuberculosis. Bone and joint tuberculosis, with spinal tuberculosis accounting for approximately 50%, represents a significant form of extrapulmonary tuberculosis. Over the past years, there has been a rise in the incidence of spinal tuberculosis, and research concerning this area has gained significant attention. At present, animal models provide a means to investigate the pathogenesis, drug resistance, and novel treatment approaches for spinal tuberculosis...

Background: To observe the activation strategies of the ankle muscles using surface electromyography (sEMG) during single-leg standing (SLS) and both-leg standing (BLS) on flat ground (FG), soft mat (SM), and BOSU ball (BB) surfaces. Methods: Thirty healthy young adults participated in the study. The muscle activities of the tibialis anterior (TA) and gastrocnemius medial (GM) were measured on the three surfaces during SLS and BLS. Electromyographic evaluations of the TA and GM were recorded during maximum voluntary isometric contractions (MVIC)...

Purpose: To investigate the disease activity in real-world patients with rheumatoid arthritis (RA) who switched from originator etanercept (ETN) to biosimilar YLB113. Methods: Forty one RA patients who switched from ETN to YLB113 were divided into 2 groups based on the Disease Activity Score based on the 28-joint count (DAS28) 12 months after switching (R group: DAS28 < 2.6, N group: DAS28 ≥ 2.6), and the baseline characteristics were statistically examined. A receiver operating characteristics (ROC) analysis was performed to estimate the cut-off value of DAS28 at baseline to achieve remission 12 months after switching...

PURPOSE: A fundamental understanding of plantar pressure distribution is important for prescribing an appropriate orthosis and applying nonoperative methods, such as stretching exercises, for the treatment of plantar fasciitis. Despite existing research on plantar pressure distribution, discrepancies between affected and unaffected sides in unilateral plantar fasciitis patients warrant further investigation. This study aimed to evaluate the plantar pressure distribution in patients with unilateral plantar fasciitis by comparing it with that on the contralateral unaffected side...

Purpose: There are various surgical interventions available for the management of Chronic lateral ankle instability (CLAI). The Broström-Gould procedure has gained widespread recognition among foot and ankle specialists for its favorable surgical outcomes. However, with advancements in anatomical understanding and medical technology, further enhancements to the effectiveness of the Gould procedure are warranted. This study introduces a all-inside modified "outside-in" Broström -Gould procedure as an alternative approach for addressing lateral ankle instability...

Background: The purpose of this study was to investigate the effect of 3D-printed technology to repair glenoid bone defect on shoulder joint stability. Methods: The shoulder joints of 25 male cadavers were tested. The 3D-printed glenoid pad was designed and fabricated. The specimens were divided into 5 groups. Group A: no bone defect and the structure of the glenoid labrum and joint capsule was intact; Group B: Anterior inferior bone defect of the shoulder glenoid; Group C: a pad with a width of 2 mm was installed; Group D: a pad with a width of 4 mm was installed; Group E: a pad with a width of 6 mm was installed...

PURPOSE: To describe the implementation and evaluation of a hospital-initiated, community-based, digital prehabilitation program ( My PreHab Program : MPP ) for adults referred for elective joint replacement. METHODS: MPP was implemented July 2022 and comprises a personalised digital health screen that guides the provision of self-management resources. Adults (<u>></u>18 years) referred and accepted, or already waitlisted, for total knee/hip replacement surgery were eligible...

BACKGROUND: While previous research has demonstrated potential advantages of unicompartmental knee arthroplasty (UKA) over total knee arthroplasty (TKA), particularly in terms of clinical outcomes such as function and pain relief, the specific impact on health-related quality of life (HRQOL) remains unclear. This systematic review and meta-analysis aim to address this gap by comparing HRQOL outcomes between UKA and TKA, providing valuable insights for clinical decision-making. METHODS: We conducted a literature search in the PubMed, Embase, Cochrane Controlled Register of Trials (CENTRAL), and Web of Science databases up to July 15, 2023...

PURPOSE: The abnormal function and survival of chondrocytes result in articular cartilage failure, which may accelerate the onset and development of osteoarthritis (OA). This study is aimed to investigate the role of LINC01094 in chondrocyte apoptosis. METHODS: The viability and apoptosis of lipopolysaccharide (LPS)-induced chondrocytes were evaluated through CCK-8 assay and flow cytometry analysis, respectively. The expression levels of LINC01094, miR-577 and MTF1 were detected by qRT-PCR...

BACKGROUND: Glucocorticoids have been widely used in perioperative period for postoperative pain relief after total knee arthroplasty (TKA). However, the optimal administration protocols of glucocorticoids remain controversial. This study aims to compare the efficacy of glucocorticoids between intravenous and periarticular injection on clinical outcomes.
