Objective: This study aimed to explore whether total hip arthroplasty (THA) aided by full-process robotics was effective in patients undergoing developmental dysplasia of the hip (DDH).
Methods: Totally 112 patients were enrolled and classified into robotic-assisted group (n = 56) and the conventional group (n = 56). In addition, retrospective analysis was used for comparing the difference in therapeutic efficacy.

Objective: To evaluate the early effectiveness of navigation-free robot-assisted total knee arthroplasty (TKA) compared to traditional TKA in the treatment of knee osteoarthritis combined with extra-articular deformities.
Methods: The clinical data of 30 patients with knee osteoarthritis combined with extra-articular deformities who met the selection criteria between June 2019 and January 2024 were retrospectively analyzed. Fifteen patients underwent CORI navigation-free robot-assisted TKA and intra-articular osteotomy (robot group) and 15 patients underwent traditional TKA and intra-articular osteotomy (traditional group).
Objective: Dysregulated lipid metabolism enhances the development and advancement of many cancers, including osteosarcoma (OS); however, the underlying mechanisms are still largely unknown. Therefore, this investigation aimed to elucidate novel potential lipid metabolism-related long non-coding RNAs (lncRNAs) that regulate OS development and provide novel signatures for its prognosis and precise treatment.
Materials And Methods: The GEO datasets (GSE12865 and GSE16091) were downloaded and analyzed using R software packages.
Background: Intervertebral disc degeneration (IVDD) is the initiating factor of adult degenerative scoliosis (ADS), and ADS further accelerates IVDD, creating a vicious cycle. Nevertheless, the role of the Wnt/β-Catenin pathway in ADS combined with IVDD (ADS-IVDD) remains a mystery. Accordingly, this study was proposed to investigate the effect of axial stress on the Wnt/β-Catenin pathway in nucleus pulposus cells (NPCs) isolated from DS-IVDD patients.

Thus, this study investigated the relationship between distal medial cuneiform obliquity and hallux valgus by measuring various angles in weightbearing anteroposterior radiographs of the foot. In total, 679 feet of 538 patients with the radiographs were included in the study.

Surgery is the main treatment for osteonecrosis of the femoral head, and quadratus femoris muscle pedicle bone grafting has a definite therapeutic effect as one method of surgery for the treatment of ONFH. However, the posterior superior retinacular artery is often injured during quadratus femoris muscle pedicle bone graft surgery.

Objective: To investigate the safety and efficacy of a new biodegradable magnesium internal fixation screw for vascularized iliac bone flap grafting in treatment of osteonecrosis of the femoral head (ONFH).
Methods: Patients with ONFH admitted between July 2020 and February 2021 were selected as the research objects, and 20 patients (20 hips) met the selection criteria and were included in the study. The patients were divided into two groups ( =10) by central random method.
Background: For periacetabular osteotomy, traditional approaches usually have a long learning curve. We aimed to evaluate the postoperative results and complications of periacetabular osteotomy under a new double-incision approach.
Methods: The records of 58 consecutive patients (65 hips) who underwent periacetabular osteotomy using the new approach were retrospectively reviewed and evaluated.

Objective: To observe the effectiveness of digital subtraction angiography (DSA) assisted musculoskeletal flap transplantation in the treatment of osteonecrosis of the femoral head (ONFH).
Methods: The clinical data of 15 patients with 15 hips of ONFH admitted between January 2016 and December 2019 were retrospectively analyzed. All patients were male, aged 20-45 years, with an average age of 31.
The present study aimed to investigate the molecular mechanisms of cyclic stretch-induced apoptosis in human intervertebral disc cartilage endplate-derived stem cells (CESCs). CESCs were stretched by the Flexercell-4000 Tension Plus system, the effect on cell viability was measured by a Cell Counting Kit-8 assay, while cell apoptosis was detected by flow cytometry. Western blot analysis was used to evaluate the expression of B-cell lymphoma 2 (Bcl-2)/adenovirus E1B 19 kDa interacting protein 3 (BNIP3), Bcl-2, Bcl-2 homologous antagonist killer (Bak), Bcl-2-associated X protein (Bax), Bcl extra large (Bcl-xl) and the activity of caspase-3, while Z-VAD-FMK was used to inhibit caspase-3.

However, the underlying mechanisms have yet to be thoroughly elucidated. The present study created a cell culture model under ND conditions to investigate the roles of the nutrient‑sensitive protein B‑cell lymphoma 2/adenovirus E1B 19 kDa‑interacting protein (BNIP3) and the mitochondrial pro‑death protein apoptosis‑inducing factor (AIF) in the death pathway of NP cells.

Nutrition deficiency is reported to induce apoptosis of chondrocytes and degeneration of cartilage endplate (CEP) in rabbit. Cartilage endplate stem cells (CESCs) are important for the integrity of structure and function of CEP. Bcl-2/adenovirus E1B 19-kDa-interacting protein 3 (BNIP3) has been reported to regulate apoptosis, autophagy, and cytoprotection.
