In this special issue, several papers related to clinical application of arthroscopic surgery are published, which present the current situation of arthroscopic techniques in our country. As a technique of minimally invasive orthopedics, arthroscopy is used in examination, diagnosis and treatment of joint diseases, which is the trend of modern surgery. Arthroscopy has been widely used in surgical procedures in knee diseases, and now it expands the scope of application to other joints, such as shoulder, elbow, wrist, hip, ankle and even smaller joints. The application scope of arthroscopy has spread from arthroscopic debridement to reparative and reconstructive surgery. Some innovation has been made in extra-articular surgeries. Researchers conduct in depth study and exploration in the basic and clinical application of arthroscopy. Arthroscopic surgery has become an indispensable branch of modern orthopedics.

Almost 50% of patients with inflammatory bowel disease (IBD) exhibit at least one extra-intestinal manifestation in their lifetime. Extra-intestinal manifestations of IBD are often associated with the intestinal disease activity, reducing the quality of life of the patient but rarely leading to fatal complications. Musculoskeletal involvement is the most frequent extra-intestinal manifestation of patients with IBD but this rarely occurs before IBD is diagnosed. They are manifested in various forms, such as arthropathy, fibromyalgia, and osteoporosis. Therefore, a multidisciplinary team approach including gastroenterologists and rheumatologists are necessary for optimal treatment. This review focuses on the diagnosis and treatment of musculoskeletal manifestations of IBD from the perspectives of rheumatologists who can assist gastroenterologists.

PURPOSE: The purpose of the present study was to perform a pattern analysis in patients with temporomandibular disorder (TMD) resulting from unilateral mastication due to chronic periodontitis. METHODS: Thirty participants with signs or symptoms of TMD who engaged in unilateral mastication due to periodontitis-related discomfort (test group) were selected. Another 30 subjects exhibiting signs or symptoms of TMD resulting from unilateral mastication not due to chronic periodontitis (control group) were also recruited. An interview-based questionnaire was administered, and an examination of the temporomandibular joint (TMJ) with determination of periodontal status was performed. RESULTS: The duration of unilateral mastication was significantly longer in the control group than in the test group. There was a significant negative correlation between the duration of unilateral mastication and the Community Periodontal Index score. Using the Research Diagnostic Criteria for TMD (RDC/TMD) axis I algorithms, all the subjects were assigned to 3 main groups. The test group exhibited significantly a higher diagnostic distribution of group III (arthralgia, osteoarthritis, or osteoarthrosis), and in both the test and control groups, the number of diagnoses was larger for the non-chewing side. The control group showed a significantly higher diagnostic distribution of group I (myofacial pain), and in both the test and control groups, the number of diagnoses was larger for the chewing side. CONCLUSIONS: The results of the present study indicate that unilateral mastication due to chronic periodontitis could induce not only pain but also structural TMJ changes if adequate treatment is not administered and supported within a short time from the onset of the condition. Therefore, immediate treatment of chronic periodontitis is recommended to prevent not only the primary progress of periodontal disease, but also secondary TMJ-related problems. Furthermore, subjects who have suffered chronic long-term periodontitis without treatment should be urged to undergo a TMJ examination.

Congenital anomalies of the spine are frequent and variable. Some are restricted to skeletal structures, while others involve combined neural tube defects or are associated with other multi-systemic disorders. Structural spinal anomalies can be classified according to their location: 1) the vertebral body, 2) the articular process, 3) the lamina with spinous process, 4) the pars interarticularis, 5) the facet joint, 6) the pedicle, or 7) other. Because of similarities between these congenital anomalies and (a) secondary changes involving infection or joint disease and (b) deformities resulting from trauma and uncertain tumorous conditions, significant confusion can occur during diagnosis. Moreover, since the anomalies often give rise to both functional impairment and cosmetic problems, appropriate treatment relies crucially on accurate diagnosis. The authors illustrate the pathogenesis and radiologic findings of the relatively common spinal anomalies confined to skeletal structures.

Objective To explore the clinical characteristics of relapsing polychondritis(RP)patients presented with arthropathy. Methods We retrospectively analyzed the clinical data of 201 RP patients who were hospitalized in our center between December 2005 and February 2019.After 16 patients with co-existing other autoimmune diseases and malignancies were ruled out,185 RP patients entered the final analysis,among whom 16 RP patients were presented with arthropathy and 169 without arthropathy.The demographic data,clinical manifestations,laboratory findings,and prognosis were compared between these two groups. Results Five of the 16 RP patients with arthropathy at presentation were misdiagnosed as rheumatoid arthritis.Compared with RP patients without arthropathy at presentation,RP patients with arthropathy at presentation had a longer disease course[(37.50±66.50)months

Infection is a frequent problem in patients with systemic lupus erythematosus (SLE). Infections contribute greatly to the morbidity of patients and are one of the commonest causes of death. The high frequency and unusual spectrum of infections can be attributed to the multiple disturbances of immune function in SLE in combination with the effects of immunosuppressive therapy. There is increasing evidence to indicate that opportunistic infections including tuberculosis make a large contribution to the infectious mortality in SLE. Tuberculosis is a major cause of morbidity and mortality, particularly in our country where tuberculosis is still endemic. The indolent nature of tuberculous bone and joint disease often leads to delayed or missed diagnosis, sometimes with devastating consequences for the patient. We report a case of multifocal and complicated osteoarticular tuberculosis developing in the spines and knee joint due to delayed diagnosis, with review of literatures.

The camptodactyly-arthropathy-coxa vara-pericarditis syndrome (CACP) is characterized by congenital or early-onset camptodactyly, childhood-onset noninflammatory arthropathy associated with synovial hyperplasia. Some patients have pro-gressive coxa vara deformity and/or noninflammatory pericardial effusion. CACP is inherited as an autosomal recessive mode and the disease gene is assigned to a 1.9-cM interval on human chromosome 1q25-31. We describe a 10-yr-old boy who has typical features of CACP without familial association.

Rheumatoid arthritis (RA) is the most common chronic inflammatory joint disease. The prevalence of RA is between 0.5~1% and annual incidence of RA is approximately 0.2~0.4/1,000 persons. The prevalence and incidence of RA appear to have fallen in the last 50 years. Risk factors for the development of RA include genetic factors, hormonal factors, reproductive factors, environmental factors and life-style factors. The currently accepted classification scheme for RA is the 1987 American Rheumatism Association (ARA) criteria. This criteria is both sensitive and specific, but it has limitation in classifying early disease.
