Radiation synovetomy with various radiopharmaceuticals has been used to alleviate pain and swelling of rheumatoid arthritis and related joint diseases for more than 40 years. It is an attractive alternative to the surgical synovectomy for the management of the various joint diseases. Recently, the development of new radiopharmaceuticals labeled with $^{90}Y,\;^{32}P,\;^{186}Re,\;^{188}Re,\;^{153}Sm,\;^{165}Dy$ and $^{166}Ho$, for the effective management of synovial inflammation and related arthritic problems are gaining attention. In this article the general concepts and the clinical application of radiation synovectomy are reviewed.

Spontaneous osteonecrosis of the knee was first described by Ahlbck et al in 1968 as the spontaneous and sudden onset of severe pain, usually on the medial side of the knee joint, in old age(>60 years) with no specific etiologic factors. They differentiate the disease from osteochondritis dissecans, osteoarthritis, fracture, infection, neuropathic joint and secondary osteonecrosis of the knee joint. So far many investigators described this disease but had never observed cases developed in young patient with familial occurrence. The report presented here is a case of spontaneous osteonecrosis of both medial and lateral femoral condyles involving the bilateral knee joint that were treated by arthorscopic loose body removal and multiple drilling.

Degenerative arthritis is characterized by progressive degenerative change, particularly change occurring to the joint due to the burden of body weight. Arthritis means inflammation occurring to the joint: it causes pain and limits exercise involving movement of the joint. Edema is not a disease but a condition which is accompanied by progression of a certain disease. Degenerative arthritis patients also have various diseases and mostly brings edema. Even though the cause is known to be abrasion of the joints, there are many cases in which walking difficulties are caused by pressure and pain due to edema. We found patients with walking difficulties caused by pain and increase of pressure in the joints walk better after treatment of both the pain and edema.

Sarcoidosis is a multi systemic granulomatous disease of unknown etiology and pathogenesis. The granulomas are non-caseating, and the organs that are affected most frequently are the lungs, the skin, and the eyes. However it may also involve the liver, spleen, bone, nervous system, and other organs. The diagnosis is based on the identification of noncaseating granuloma in the tissues involved, excluding other granulomatous conditions. The diagnosis of sarcoid joint disease is often made in retrospect and only when the lung or eye is involved. We report a case of sarcoid synovitis in knee joint with review of literature.

Background : Mesenchymal stem cells (MSCs) are present in most of the tissue matrix, taking part in their regeneration when injury or damage occurs. The aim of this study was to investigate the presence of cells with pluripotential characteristics in human subchondral bone and the capacity of these cells to differentiate to osteoblast. Methods : Human subchondral bone were digested with collagenase. Isolated cells were cultured with a-MEM, 15% FBS, 10-8M dexamethasone and 50 ng/mL ascoric acid. Cells from 0 day(isolated cells), 7 day (first subculture) and 14 days (third subculture) were used to carry out phenotypic characterization experiments flowcytometry analysis with 11 monoclonal antibodies) and osteogenic differentiation experiments. Osteogenic differentiation of cells was assessment by quantification of bone extracellular matrix components by following analysis: alkaline phosphatase(ALP) stains to detect ALP activity, RT-PCR and western blot to detect osteocalcin (OCN), osteopontin (OPN) and type I collagen(Col I), and Alizarin red stains to detect calcium deposition. Results : Flowcytometry analyses showed that in our population more than 98% of cells were positive for MSC markers: SH-2(CD105, 99%), CD29 (95%), CD73 (95%). Cells were negative for hematopoietic markers (CD11b, CD34, and CD45). Furthermore, cells showed positive stain to multipotent markers such as CDl17 (c-kit) (15.1%), and CD166 (74.9%), and cell adhesion molecules such as CD54 (78.1%) and CD106 (63.5%). The osteogenic specific marker analyses showed that the culture of these cells for 7 and 14 days stimulates ALP, OCN, OPN and Col I synthesis by RT-PCR and Western blot analysis. Also, after 14 days in the culture of MSCs induces mineralization by Arizarin red stain. Conclusion : In this work, we demonstrated a new and efficient method for osteoblastic differentiation of human subchondral bone stem cells. As MSCs takes part in reparative processes of adult tissues, these cells could play an important role in osteogenesis.

Purpose: The purpose of this study was to examine the effects of cardiocerebrovascular disease prevention program for older adults who were members of a elderly school located in Y city on knowledge of cardiocerebrovascular disease, depression, and physiological parameters. Methods: Nonequivalent control group pretest-posttest design was employed. A total of 50 older people living in Y city were assigned into an experimental group (n=26) or a control group (n=24). The experimental group participated in a 8-weeks cardiocerebrovascular disease prevention program from October 10 to December 2 in 2016. Data were analyzed with SPSS/WIN 21.0 using descriptive statistics, $x^2$ test, Fisher's exact test, and t-test. Results: The results indicated significant differences between the experimental group and control group in the scores of knowledge of cardiocerebrovascular disease (t=-4.60, p<.001), depression(t=3.65, p=.001), physiological parameters including systolic blood pressure (t=6.58, p<.001), diastolic blood pressure (t=4.56, p<.001), and blood glucose level (t=3.04, p=.004). Conclusion: The cardiocerebrovascular disease prevention program have a significant effect on the change of knowledge of cardiocerebrovascular disease, depression, and physiological parameters for elderly school participants.

Measuring the movement of joint angle of human body is very important clinically. Human joint angle displacement can be used to evaluate the degree of disease and disability. Also, we can determine the rehabilitation process with angular information. Conventional methods for measuring angular displacement are many weakness. The purpose of this study is to overcome the limitations of existing equipments by using optical method. For this reason, optical sensor system was used to correlate detected light signal with joint angle. Experimental results of the applied joint model in this study showed that joint angular displacement can be measured by optical signals. The suggested method is simple, durable, small, lightweight, convenient, and cost effective.

The technique of AKA were devised and modified several times after clinical trials to obtain better result and were though to be few years ago. The published literatures on joint mobilization were unsatisfactory to me since the subject of treatment was not confined to the synovial joint and techniques seemed too violent to treat diseased joints. Among the techniques distraction gliding and the use of convex-concave rule by F. M. Kaltenborn were acceptable theoretically but they required considerable technical modification. By that time it was evident that pain in numerous painful conditions including organic regions could be eliminated by AKA new disease entitles such as aseptic arthritis of the sacroiliac joint, hip joint, shoulder joint, 1st costovertebral joint etc and periradiculitis were elucidated.

Arthritis is a common disease in aged people, and is clinically divided into rheumatoid arthritis (RA) and osteoarthritis (OA). Although common symptoms such as pain are present, the underlying pathological mechanisms are slightly different. Therefore, the objectives of the present study were to compare joint damage induced by RA and OA by analyzing the major morphological and molecular differences, and to propose a suitable therapeutic intervention based on the pathophysiological conditions of bones and joints. For the RA animal model, 8-week-old DBA1/J mice were immunized with bovine type II collagen emulsified in complete Freund's adjuvant (CFA). Normal C57BL/6 mice (over 2 years of age) were used for OA. The clinical arthritis score was calculated using a subjective scoring system, and paw thicknesses were measured using calipers. The serum TNF ${\alpha}$ level was analyzed using an ELISA kit. Micro-CT was used to identify pathological characteristics and morphological changes. In collagen-induced RA mice, there were increased ankle joint volumes and clinical scores (p<0.01). The concentration of TNF ${\alpha}$ was significantly increased from 3 to 7 weeks after immunization. Micro-CT images showed trabecular bone destruction, pannus formation, and subchondral region destruction in RA mice. OA among aged mice showed narrowed joint spaces and breakdown of articular cartilage. This study suggests that a careful therapeutic intervention between RA and OA is required, and it should be based on morphological alteration of bone and joint.

The Temporomandibural joint(TMJ) is one of the most frequently used joint in the body as $1,500{\sim}2,000$ times per day for the activities of chewing, swallowing, talking, yawing and sneezing. The TMJ are formed by condylar process of mandible and mandible fossa of temporal bone, separated by an articular disc. This articular disc divides into two cavities as upper cavity and lower cavity. The gliding movement occurs in the upper cavity of the joint, whereas hinge movement occurs in the lower cavity. The movements that are allowed at the TMJ are opening, closing, protrusion, retraction and lateral movement. A cause of TMJ dysfunction are capsulitis, internal derangement, osteoarthritis, rheumatoid arthritis, infection and inflammation near the joint, trauma on joint, ankylosis, subluxation or dislocation of joint, injury of articular disc, myositis, muscle contracture or spasm, myofascial pain dysfunction syndrome, dyskinesia of masticatory muscles, developmental abnormality, tumor, connective tissue disease, fibrosis, malocclusion, swallowing abnormality, wrong habits such as bite nail or hair, bruxism, psycological stress and Costen syndrome etc. Assessment of TMJ dysfunction consist of interview, observation, functional examination, palpation, reflex test, joint play test, electromyography and radiologic examination and behavioral and psycological assessment etc.
