This is a report on a aseptic synovitis diagnosed and treated arthroscopically following the meniscal repair using biodegradable Meniscus Arrow$^{(R)}$(Bionix Inc, Malvern, USA). Histological examination revealed chronic nonspecific synovitis and birefringent material. Immunohistochemical tests were positive in lysozyme, ${\alpha}$-1-antitrypsin and ${\alpha}$-1-antichymotrypsin. The patient was received arthroscopic synovectomy, and then pain and swelling of the knee joint was relieved. Range of motion was improved to full range. As far as we know, this is the first case of aseptic synovitis after meniscal repair using biodegradable Meniscus Arrow$^{(R)}$.

Treatment options are limited for young, meniscal-deficient patients with pain. This patient population is not age appropriate for total joint replacement, but the loss of the meniscus leaves them at significant risk for the development of osteoarthritis. One increasingly popular option is the use of allograft meniscal transplantation. However, many questions still surround allograft meniscus transplantation. Furthermore, most reports in the literature on the results of meniscal transplantation describe small case series using clinical outcome measures and/or incomplete direct evaluation of the meniscus. Therefore, the results of meniscal allograft transplantation have been difficult to interpret and compare due to many confounding variables. In this study, we reviewed the current research of concerns on the results of meniscal allograft transplantation.

Recently, meniscal allograft transplantation has been regarded as a successful procedure in terms of pain relief and functional improvement for the symptomatic patients previously underwent subtotal or total meniscectomy. However, the likelihood of a successful outcome would be reduced by various complications including graft tear, shrinkage, extrusion, infection, progressive chondral injury, and granuloma due to nonabsorbable suture material. Therefore, knee surgeons need to be all aware of the complications and to make an effort to minimize them. The purpose of this article is to review the current literatures regarding clinical results and complications after meniscus allograft transplantation.

The prevalence of anterior cruciate ligament (ACL) injury is continuously increased due to sports activities and traffic accident. Simultaneously ACL reconstruction operations are on the increase. Several kinds of autografts and allografts are used in ACL reconstruction. Although ACL reconstruction using an autogenous bone-patellar tendon-bone graft is the good standard, it might have potential morbidity, anterior knee pain and minimal extension loss. To minimize the complications and disadvantages on each graft and to select appropriate graft for each patient, it is necessary to understand the unique characteristics of each graft for biomechanical aspect, morbidity and disadvantage. Selecting the appropriate graft depends on numerous factors including surgeon's preference and experience, patient's activity level and age, extent of ligament injury, tissue availability, and patient's selection for graft .

Objectives: This study aims to investigate the prevalence of musculoskeletal symptoms and factors related to daily activities in a representative Korean population. Methods: This study was based on the questions about musculoskeletal symptoms in the Korean General Social Survey 2010. The questionnaire about musculoskeletal symptoms was adopted from Korean Occupational Safety and Health Agency guide, and it includes general characteristics, characteristics of pain, work type, work intensity and a 12-item Short Form Health Survey (SF-12). We utilized the criteria of the National Institute for Occupational Safety and Health to define the prevalence of musculoskeletal symptoms. Demographic, behavioral and socioeconomic factors were analyzed using logistic regression. Results: The prevalence of musculoskeletal symptoms was 38.3%. The prevalence was higher in females, the elderly, those without health insurance, and those with a low income, low education, and occupations with a heavy workload. The prevalence by body part was highest in the back, shoulder, and knee, in that order. The physical component summary and mental component summary of the SF-12 decreased with increasing musculoskeletal symptoms. Conclusions: Musculoskeletal symptoms are very common in the general population, and related to various socio-demographic factors. These results suggest that active prevention and management of musculoskeletal symptoms is needed at a national level.

Sparassis crispa (Wulf.) is an edible/medicinal mushroom and has been reported to biological activities such as antitumor, anti-angiogenesis, antioxidant and wound healing. However, there have not been many researches on osteoarthritis of S. crispa. The aim of this study was to investigate the effects of S. crispa extract on rats with osteoarthritis induced by MIA. Osteoarthritis is a gradually developmental disease that early stage, causes joint stiffness and complains of joint pain. In addition, it gives rise to edema and hypo-function. The results of this study, S. crispa extract effectively inhibited ROS production, increased the production of antioxidant protein SOD and catalase in knee joint cartilage tissue. In addition, S. crispa extract inhibited the expression of pro-inflammatory cytokines and enzymes such as NOX4 and $P47^{phox}$, which are involved in the expression of COX-2, iNOS and the production of ROS. Also, S. crispa extract inhibited the destruction of synovial tissue, cartilage tissue and proteoglycans in articular cartilage in rats.

The number of reported cases with dual disability is increasing for the past few decades. Currently, dual disability of lower limb amputation and motor weakness after stroke became a strong issue in public concern. The functional levels of patients have shown in the wide range from independent community ambulation to non-ambulation. Thus, it indicates that favorable outcomes for dual disability may depend upon adopted rehabilitative strategies. We present the case of a man with left below-knee amputation and severe right-sided weakness following a huge putaminal hemorrhage. He had suffered from extreme pain and misfit of the prosthetic socket and the complicated residual limb for three years prior to the stroke. Forty days post-stroke, we performed a revision surgery to resolve the complications of bony overgrowth, verrucous hyperplasia, and neuroma and applied an ankle foot orthosis (AFO). Two years post-stroke, he was able to ambulate outside his home and negotiate stairs using a cane. This is the first case with the dual disability of lower limb amputation and contralateral hemiplegia to undergo revision surgery. The results suggest that an early revision surgery and use of an AFO are crucial for achieving a higher level of mobility in such cases.

Objectives : This study aimed to investigate the effects of electroacupuncture (EA), the laser acupuncture (LA) and the combination therapy (LA+EA) in a collagenase-induced osteoarthritis rat model. Methods : Osteoarthritis rat model was induced by injection of collagenase into left lower articular cavity (50 μl to knee and 10 μl to ankle). In order to assess the anti-osteoarthritic effects of EA, the 650 nm LA and 650 nm LA+EA, the histopathological findings and plantar withdrawal responses were analyzed. Results : All of the treatment methods used in this study were effective in reducing pain. All treatment groups were effective in decreasing inflammatory cytokines of TNF-a and IL-6; the 650 nm LA and 650 nm LA+EA groups significantly reduced IL-1β. Conclusions : 650 nm LA and EA inhibit the production of collagenase-induced inflammatory mediators of osteoarthritis.

Arthritis is a major cause of joint pain, stiffness, and subsequent disability which adversely affects quality of life. Seriously, it can lead to long term social and psychological effects including loss of independence, depression, and anxiety. Arthritis is usually treated with joint replacement surgery or medications. However, the artificial joint is temporary and pharmacological measures have side effects, such as addiction or hypersensitivity. Thus, orthotics has been developed to improve arthritis as a nonpharmacological measure. The increased regional load across compartments of articular cartilage is an important factor in the cause of the arthritis. Mubal$^{(R)}$, a clinical shoe insole, has a sliding function to help people to walk straight and realign the body balance. The slide of Mubal$^{(R)}$ reduces the knee joint loading in patients with arthritis. In addition, pumping function of Mubal$^{(R)}$ can mitigate arthritis by stretching the squashed nerves from lumbar to cervical vertebral and actively circulating blood of pelvic limb. In addition, Mubal$^{(R)}$ could help to stimulate the growth plate. Therefore, Mubal$^{(R)}$ can be used for the child with short stature as well as patients with arthritis.

Pigmented villonodular synovitis(PVNS) usually presents as a benign proliferative monoarticular arthritis that affects the knee in 80% of cases, followed in frequency by the hip, ankle, and calcaneocuboid joint. PVNS rarely affects temporomandibular joint area. Patients typically complain of pain, locking, and recurrent swelling. Tumor progression limits the range of movement of the joint and causes it to become stiff and firm. Sometimes a palpable mass can be appreciated. Aggressive form of PVNS invades into adjacent bones and soft tissues, is confused with other types of neoplasia. Here we report 2 cases of the PVNS on a temporomadibular
