BACKGROUND Nineteen patients with septic arthritis of the glenohumeral joint were treated with a combination of arthroscopic irrigation and débridement and systemic antibiotics according to bacterial sensitivity. We retrospectively reviewed the series to determine the efficacy and safety of this treatment. METHODS There were seventeen men and two women,(More)
BACKGROUND We evaluated interobserver and intraobserver reliability of the classification and treatment of acromioclavicular (AC) joint dislocations and assessed the impact of adding 3-dimensional computed tomography (3D CT) on the reliability of classification and treatment choice. METHODS Ten surgeons independently reviewed plain radiographs and 3D CT(More)
OBJECTIVE The objective of this study was to investigate the roles of dickkopf-1 (DKK-1) and integrin-related focal adhesion kinase (FAK) by TNF-α on the migration of fibroblast-like synoviocytes (FLSs) in RA. METHODS Wound scratch assays were performed to assess FLS migration. Western blotting was used to measure the levels of DKK-1, Wnt signalling(More)
We investigated the effects of a novel peroxisome proliferator-activated receptor gamma (PPARgamma) agonist, KR62776, on osteoclast differentiation and function, and on the underlying signaling pathways. KR62776 markedly suppressed differentiation into osteoclasts in various osteoclast model systems, including bone marrow mononuclear (BMM) cells and a(More)
The authors studied the short-term outcomes of total hip arthroplasty (THA) performed using large diameter femoral heads or bipolar arthroplasty (BA) in physiologically active elderly patients with displaced intracapsular femoral neck fractures. The THA group included 14 males and 66 females with a mean age of 75.5 years, and the BA group included 16 males(More)
HYPOTHESIS The purpose of this study was to develop and validate a disease-specific appraisal method for patients with rotator cuff disorders. The Korean Shoulder Scoring System (KSS) includes 5 domains totalling 100 points: function, 30 points; pain, 20; satisfaction, 10; range of motion, 20; and muscle power, consisting of strength, 10; and endurance, 10.(More)
BACKGROUND We evaluated the integrity and functional outcomes of rotator cuff tear after performing the double-pulley suture bridge (DPSB) repair technique according to the tear size by using serial ultrasonographic examinations. MATERIALS AND METHODS The study included 41 consecutive arthroscopic rotator repairs using the DPSB technique. The average(More)
In vivo microstructures of the affected feet of collagen-induced arthritic (CIA) mice were examined using a high-resolution synchrotron radiation (SR) X-ray refraction technique with a polychromatic beam issued from a bending magnet. The CIA models were obtained from six-week-old DBA/1J mice that were immunized with bovine type II collagen and grouped as(More)
