INTRODUCTION: Temporomandibular disorders encompass a set of clinical conditions that affect the temporomandibular joint, the masticatory muscles and the associated tissues. Many therapeutic alternatives can be considered, being divided into non-invasive, minimally invasive and invasive interventions. This work aims to report a case of inflammatory joint pain and dysfunction treated with bilateral TMJ full reconstruction with alloplastic prosthesis stock. CASE REPORT: Patient D...

CASE: A 53-year-old man presented with osteoarthritis (Walch biconcave [B2] glenoid retroversion, 22°; glenohumeral subluxation index, 65%) and a partial rupture of the supraspinatus tendon in the left shoulder. Following anatomic total joint replacement, he developed disabling recurrent posterior subluxation despite a stable prosthesis and a correctly centered glenoid head, as observed with postoperative radiography and computed tomography. In order to avoid bone loss and the complications associated with revision arthroplasty, we performed arthroscopic reefing of the posterior capsule as an experimental minimally invasive treatment...

PURPOSE: Improper seating of abutment on the implant is a common problem. This study investigated the effect of the type of implant/abutment interface on the complete seating of the abutments on the head of implants placed at different gingival depths. MATERIALS AND METHODS: Three implant systems with three different connections including straight external hexagon, butt-joint internal tri-lobed, and conical internal hexagon were used. Two gingival thicknesses (2 and 7 mm) were created using pink baseplate wax around the straight abutments seated on the implants...

Total knee replacement (TKR) has been performed for patients with end-stage knee joint arthritis to relieve pain and gain functions. Most knee replacement patients can gain satisfactory knee functions; however, the range of motion of the implanted knee is variable. There are many designs of TKR implants; it has been suggested by some researchers that customized implants could offer a better option for patients. Currently, the 3-dimensional knee model of a patient can be created from magnetic resonance imaging (MRI) or computed tomography (CT) data using image processing techniques...

Despite documented benefits, many Total Joint Replacement (TJR) patients find it difficult to access rehabilitation following discharge from hospital. One solution to improve access for TJR patients is telerehabilitation. This study aimed to assess the feasibility of introducing a telerehabilitation program for TJR patients. TJR patients at QEII Jubilee Hospital were invited to complete a questionnaire regarding their access, feelings towards and preferences in using technology. Seventy-five patients were recruited...

BACKGROUND: Existing evidence regarding the value of preoperative education and/or exercise (prehabilitation) for patients undergoing total joint replacement is conflicting. The purpose of this study was to conduct an updated, comprehensive systematic review with meta-analyses to determine the longitudinal effects and efficacy of prehabilitation on postoperative outcomes in patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA). METHODS: We searched 11 electronic databases (MEDLINE, AMED, CINAHL, Embase, Scopus, ProQuest, PEDro, SportDiscus, PsycINFO, and Cochrane) from their inception to May 2016 for randomized controlled trials that compared changes in pain, function, strength, anxiety, and hospital length of stay following THA or TKA...

: Liver transplantation is one of the treatments for haemophilic patients having severe liver cirrhosis who are infected with the hepatitis C virus. Patients with haemophilia can develop arthroplasty requiring surgical intervention, and the surgical outcomes of patients undergoing such procedures after liver transplant has not been reported. Treatment for arthropathy is important for improving the quality of life for patients who survive after liver transplantation. We report the first case of ankle arthroscopic arthrodesis in a patient with haemophilia B after undergoing living donor liver transplantation...

This final rule cancels the Episode Payment Models (EPMs) and Cardiac Rehabilitation (CR) Incentive Payment Model and rescinds the regulations governing these models. It also implements certain revisions to the Comprehensive Care for Joint Replacement (CJR) model, including: Giving certain hospitals selected for participation in the CJR model a one-time option to choose whether to continue their participation in the model; technical refinements and clarifications for certain payment, reconciliation and quality provisions; and a change to increase the pool of eligible clinicians that qualify as affiliated practitioners under the Advanced Alternative Payment Model (Advanced APM) track...

Disease-modifying antirheumatic drugs (DMARDs) have become essential treatments in the management of patients with inflammatory rheumatic diseases. Their use has resulted in a marked improvement of disease control and a limitation of joint damage, although some patients still require subsequent corrective or joint replacement surgery. Due to their immunosuppressive effects, some DMARDs are associated with an increased risk of infection. The aim of this review is to discuss the available literature on the management of DMARDs during the perioperative period, particularly in the case of orthopaedic surgery...

BACKGROUND: The rising number of primary joint replacements worldwide is causing an increase of endoprosthetic revision surgery due bacterial infection. Revision surgery using non-cemented implants seems beneficial for the long-term outcome, and the use of antibiotic-impregnated bone grafts might control the infection and provide a good support for the implant. In this study, we evaluated the release of antibiotics from fresh-frozen and lyophilized allogeneic bone grafts. METHODS: Heat-treated, lyophilized and fresh frozen cryopreserved bone chips were impregnated with gentamicin sulphate, gentamicin palmitate and vancomycin, and calcium carbonate/calcium sulphate treated with antibiotics...

BACKGROUND: The 'demand planning guidelines' issued by the Federal Joint Committee are meant to ensure nationwide delivery of healthcare in Germany. The calculatory variable used to reflect the actual care situation in relation to a given geographical entity is referred to as 'adjusted supply rate'. Against the backdrop of demographic change and already existing problems in replacing retiring physicians, the question arises as to how future dermatological care will evolve at the regional level...

The introduction of new materials and better implant coatings seems to provide the prerequisites for more intense physical activities after total joint arthroplasties of the lower extremity. Despite recent advances in implant design and materials, recommendations for sport after total joint arthroplasty have not been updated over the past 20 years. The introduction of modern uncemented fixation as well as highly cross-linked polyethylene into total hip arthroplasty allow for a more active life-style without an increased risk of loosening or complications...

With the increase of elderly population, orthopaedic surgeons need to deal with the diseases related to aging, such as joint disorders and fragility fractures. The number of total joint replacements, for example, is two times more than it was 10 years ago. With these backgrounds, the Japanese Orthopaedic Association (JOA) has proposed the concept of locomotive syndrome; conditions under which the elderly have been receiving care services due to problems of the locomotive organs. To prevent geriatric or disuse syndrome, JOA is currently providing the care‒prevention programs such as the loco-check and loco-training...

Total knee arthroplasty (TKA) is a rewarding procedure in patients with hemophilia and end stage knee hemophilic arthropathy. However, this procedure might be associated with complications such as infection. There periprosthetic joint infection in patients with hemophilia is very well known, though we are not aware of any previous report on Brucella infection in this group of patients. Here, we reported a 28-year old man with Brucella infection of total knee replacement who initially underwent a conservative treatment followed bya two-stage revision...

Background: Although evidence shows that patients with end stage renal disease (ESRD) experience a high symptom burden which impacts on quality of life (QoL), less is known about patients with earlier stages of chronic kidney disease (CKD). This study aimed to explore symptom burden and potential contributing factors in patients with CKD Stage 1-5 not requiring renal replacement therapy (RRT). Methods: Patients with CKD Stage 1-5 and not on RRT were asked to report their symptoms using the Leicester Uraemic Symptom Score (LUSS), a questionnaire which assesses the frequency and intrusiveness of 11 symptoms commonly reported by kidney patients...

Osteoarthritis is characterized by a chronic, progressive and irreversible degradation of the articular cartilage associated with joint inflammation and a reparative bone response. More than 100 million people are affected by this condition worldwide with significant health and welfare costs. Our available treatment options in osteoarthritis are extremely limited. Chondral or osteochondral grafts have shown some promising results but joint replacement surgery is by far the most common therapeutic approach. The difficulty lies on the limited regeneration capacity of the articular cartilage, poor blood supply and the paucity of resident progenitor stem cells...

BACKGROUND: Rheumatoid arthritis (RA) is a systemic, autoimmune disease leading to joint destruction and ultimately disability. Bone marrow (BM) is an important compartment in RA, where pathological processes from "outside the joint" can occur. IL-17 is a cytokine that exerts proinflammatory effects and participates in the process of bone destruction. It is believed that IL-17 is involved in pathogenesis of RA. However, little is known about the biology of this cytokine in BM. In the present study we investigated Th17-related cytokines in RA BM...

AIMS: Following the resection of an extensive amount of bone in the treatment of a tumour, the residual segment may be insufficient to accept a standard length intramedullary cemented stem. Short-stemmed endoprostheses conceivably have an increased risk of aseptic loosening. Extra-cortical plates have been added to minimise this risk by supplementing fixation. The aim of this study was to investigate the survivorship of short-stemmed endoprostheses and extra-cortical plates. PATIENTS AND METHODS: The study involved 37 patients who underwent limb salvage surgery for a primary neoplasm of bone between 1998 and 2013...

Adipose-derived mesenchymal stem cells (ASCs) have immunoregulatory properties, but their activity is dependent on signals provided by the local microenvironment. It is likely that highly inflammatory milieu of rheumatoid joint affects ASCs activity. To test this hypothesis, the function of rheumatoid ASCs derived from articular adipose tissue (AT-ASCs) and ASCs derived from subcutaneous adipose tissue (Sc-ASCs) has been analysed. Articular adipose tissue (infrapatellar fat pad) and subcutaneous adipose tissue (from the site of skin closure with sutures) were obtained from rheumatoid arthritis (RA) patients undergoing total knee joint replacement surgery...
