BACKGROUND: Apart from transepicondylar axis, the native femoral sulcus was also reported to be used as a guide for the femoral component position in total knee arthroplasty (TKA). However, it was not shown in patients with severe knee osteoarthritis. This study was conducted to compare the position of trochlear groove in patients with and without osteoarthritis, and to assess whether trochlear groove could be used as a guide for position of femoral component in TKA for severe knee osteoarthritis...

CONTEXT: Pycnogenol(®) extracted from French maritime pine bark (Pinus pinaster Ait. subsp. atlantica) is functional for its antioxidant activity. OBJECTIVE: To investigate the effects of Pycnogenol(®) on bone mineral density (BMD), trabecular microarchitecture and bone metabolism in ovariectomized (OVX) rats. MATERIALS AND METHODS: Thirty Sprague-Dawley rats were randomized into 3 groups: SHAM group (sham-operated rats), OVX group (OVX rats), and treatment group (OVX rats supplemented with 40 mg/kg Pycnogenol(®) by oral gavage)...

Osteoarthritis is an aging-related degenerative disease that severely influences the elders' life quality. However, there have been few clinical approaches available until now. Currently, more knowledge of the pathology of osteoarthritis has been illustrated. Especially, diabetes can be the only predictor of osteoarthritis. Due to its outstanding characteristics, MicroRNA has been considered as an efficient target in treating diseases. In this review, we will discuss a new insight focusing on the roles of microRNA in the progression of osteoarthritis-induced by diabetes, especially type II diabetes mellitus...

OBJECTIVE: This study investigated the effect of the knee position during wound closure on early knee function recovery after total knee arthroplasty (TKA). METHODS: This study included 80 primary total knee arthroplasties due to osteoarthritis. The patients were randomized according to the type of wound closure: extension group for full extension and flexion group for 90° flexion. The incision of articular capsule was marked for precise wound alignment. In the flexion group, the knee was kept in high flexion for 1 to 2 min after wound closure...

BACKGROUND: Dextroscope® three-dimensional (3D) imaging has been extensively used to generate virtual reality (VR) workspaces for neurosurgery and laparoscopy, but few applications have been reported for orthopedic surgery. Here, we investigated orthopedic periarticular tumor surgery planning and anatomical characteristics using a Dextroscope. MATERIAL AND METHODS: Patients undergoing surgery for periarticular tumors (n=10) between October 2008 and June 2010 were enrolled and presurgically subjected to computed tomography (CT), magnetic resonance imaging (MRI), and MRI angiography (MRI-A)...

Patients undergoing surgery for periarticular tumors (n = 10) from Oct. 2008 to Jun. 2010 were enrolled and presurgically subjected to computed tomography (CT), magnetic resonance imaging (MRI), and MRI angiography (MRI-A). Imaging data was transferred and integrated in Dextroscope, producing a VR simulation...

The CXCL12-CXCR4 axis is postulated to be a key pathway in the interaction between (cancer) stem cells and their surrounding supportive cells in the (cancer) stem cell niche. As the bone marrow constitutes a unique microenvironment for cancer cells, the CXCL12-CXCR4 axis assists the bone marrow in regulating cancer progression. This interaction can be disrupted by CXCR4 antagonists, and this concept is being used clinically to harvest hematopoietic stem/progenitor cells from the bone marrow. The functions of CXCL12-CXCR4 axis in cancer cell-tumor microenvironment interaction and angiogenesis have been recently studied...

Research has added evidence in favor of computer-navigated techniques over conventional surgery for total knee arthroplasty (TKA). The goal of the current meta-analysis was to compare the outcome of outliers in mechanical axis and postoperative complications in patients undergoing conventional vs computer-navigated techniques for TKA. English literature searches were performed in PubMed, EMBASE, Web of Science, and the Cochrane Library for studies published between January 2002 and August 2012. Randomized, controlled trials comparing computer navigation with conventional surgery for the measurement of mechanical axes in patients with primary osteoarthritis were considered eligible...

INTRODUCTION: Retrograde coronary venous infusion is a promising delivery method for cellular cardiomyoplasty. Poor cell retention is the major obstacle to the establishment of this method as the preferred route for cell delivery. Here, we explored whether magnetic targeting could enhance retrograde cell retention in a rat model of myocardial infarction. METHODS: Rat mesenchymal stem cells were labeled with superparamagnetic oxide nanoparticles. The magnetic responsiveness of MSCs was observed while cells flowed through a tube that served as a model of blood vessels in a 0...

Magnetic targeting has been recently introduced to enhance cell retention in animals with acute myocardial infarction. However, it is unclear whether the magnetic accumulation of intravascular cells increases the risk of coronary embolism. Upon finite element analysis, we found that the permanent magnetic field was nonuniform, manifestated as attenuation along the vertical axis and polarisation along the horizontal axis. In the in vitro experiments, iron-labelled mesenchymal stem cells (MSCs) were accumulated in layers predominantly at the edge of the magnet...

BACKGROUND: The purpose of this study was to investigate the clinical efficacy of extended resection with osteotomy, fenestration and conservation of muscle (tendon) insertion in the treatment of bone tumors. METHODS: A total of 15 patients with locally aggressive bone tumors (Enneking stage II) in the adjacent muscle (tendon) insertion of the proximal extremity were enrolled in the present study (mean age of 29 years). Extended curettage of lesions with osteotomy, fenestration and/or conservation of muscle (tendon) insertion and internal fixation with a bone graft or bone cement was performed at stage I...

Wide en bloc excision of proximal ulna sections is used to treat traumatic and pathological fractures of the ulna, though poor standardization of clinical treatment often results in long-term failure of such reconstructed biomechanical structures. In order to provide insight into effective ulnar reconstructive treatments, the case of an 80-year-old Chinese Han male presenting with pathological fracture caused by a proximal ulnar metastatic tumor concurrent with metastatic renal cancer complicated by occurrence in the brain and lungs is reported and contrasted with alternative treatment techniques...
