Philip K McClure, Hamza M Alrabai, Janet D Conway
Reconstruction of segmental bone defects requires a large commitment both on the part of the patient and the physician. Investing in preoperative evaluation and optimization is the only logical way to pursue such an endeavor. Unfortunately, detailed studies regarding segmental bone defects and preoperative factors are relatively lacking owing to the relatively low incidence of the problem. Fortunately, other orthopaedic pathologies (arthritis, ligamentous injuries about the knee) have high prevalence and consistency, allowing detailed analysis of preoperative factors...

INTRODUCTION: Celecoxib is an effective treatment for pain associated with osteoarthritis. There are differences in patient demographics among ethnic groups, with Asian populations typically smaller in body size. As a consequence, there may be a perception that celecoxib is less effective, or has poorer tolerability in Asian patients. METHODS: This analysis compares data from two multicenter, randomized, double-blind, placebo-controlled, active-comparator trials of celecoxib for the treatment of osteoarthritis of the knee: one study in Asian patients and the other in a mixed population comprised mostly of non-Asian patients (from which Asian patients were excluded for this analysis)...

Osteoarthritis is the most common cause of arthritis and one of the principle causes of chronic pain. Although opioids are frequently employed for chronic pain treatment, their usage for osteoarthritis pain remains controversial due to the associated adverse effects. Most guidelines reserve their use for refractory pain in patients with hip and knee osteoarthritis. The situation is even more complex in Latin America, where the prevalence of insufficient pain treatment is high because of the limited availability and use of strong opioids...

Muscle dysfunction is the most important modifiable mediating factor in primary osteoarthritis because properly contracting muscles are a key absorber of forces acting on a joint. However, the pathological features of disuse muscle atrophy in osteoarthritis patients have been little studied. Vastus medialis muscles of fourteen female patients with osteoarthritis in the age range 69 to 86 years, largely immobile for one or more years, were obtained during arthroplastic surgery and analyzed histologically. These were compared to female patients without arthritis, two with patellar fracture, and two with patellar subluxation...

Acute non-traumatic swelling of the knee is a common clinical challenge. The reason for the swelling has to be explored in order to give the correct treatment. This article gives an overview of possible diagnoses and suggests an algorithm for an approach to non-traumatic knee arthritis. Fundamental in the examination is a thorough patient anamnesis, which will help to differentiate between inflammatory and non-inflammatory arthritis. If there is not an obvious degenerative reason for the knee effusion, a joint aspiration followed by synovial fluid white cell count (WCC), microscopy and/or culture will add valuable information...

Yersinia enterocolitica (YE) biotype 1A is generally considered non-pathogenic, and the role of it in causing reactive musculoskeletal complications is unclear. We evaluated the capability of YE biotype 1A to induce reactive arthritis (ReA) and other reactive musculoskeletal symptoms. Analysis of self-reported musculoskeletal symptoms was supplemented with a telephone interview (with a permission to acquire copies of patient files from a local physician or hospital) and/or clinical examination of subjects with recent musculoskeletal symptoms after a positive stool culture for YE...

OBJECTIVE: The etiology of knee osteoarthritis (OA), the most common form of arthritis, is complex and may differ by race or ethnicity. In recent years, genetic studies have identified many genetic variants associated with OA, but nearly all the studies were conducted in European whites and Asian Americans. Few studies have focused on the genetics of knee OA in African Americans. METHODS: We performed a genome-wide association study of radiographic knee OA in 1217 African Americans from 2 North American cohort studies: 590 subjects from the Johnston County Osteoarthritis Project and 627 subjects from the Osteoarthritis Initiative...

BACKGROUND: Neuroimmune interactions play a vital role in many of the most common pain conditions, such as arthritis. There have been many attempts to derive clinically predictive information from an individual's inflammatory response in order to gauge subsequent pain perception. OBJECTIVES: Here, we wanted to test whether this effort could be enhanced and complemented by the use of a model system which takes into account the function of not just circulating, but also tissue-resident immune cells: ultraviolet B (UVB) irradiation of the skin...

OBJECTIVES: Arthritis resulting from recurrent intra-articular bleeding in individuals with hemophilia can be severely debilitating due to joint pain and stiffness with subsequent loss of mobility and function. Very limited studies have investigated the potential benefits of joint mobilization for this condition. This case series is a preliminary investigation of safety, as well as immediate and short-term clinical benefits, associated with gentle knee and ankle joint mobilization in people with hemophilic arthropathy...

The objective of this study was to investigate the expression of the chemokine CXCL10 and its role in joint tissues following articular fracture. We hypothesized that CXCL10 is upregulated following articular fracture and contributes to cartilage degradation associated with post-traumatic arthritis (PTA). To evaluate CXCL10 expression following articular fracture, gene expression was quantified in synovial tissue from knee joints of C57BL/6 mice that develop PTA following articular fracture, and MRL/MpJ mice that are protected from PTA...

Osteoarthritis (OA) of the knee is the most common type of arthritis all over the world. Obesity is the strongest modifiable risk factor and causes OA through a combination metabolic factors and mechanical loading. This study aimed to determine the frequency of metabolic syndrome (Mets) among patients with knee OA and its relationship with pain and functional status. This was a descriptive hospital-based cross-sectional study involving patients with knee OA. Pain was measured using a 0-10 numeric rating visual analog scale (VAS)...

While gouty arthritis of the knee is not uncommon, associated mechanical block to extension is a rarely seen complication. This report presents a unique case of extension loss due to a single, isolated intra-articular gouty tophus. Only a few similar reports have been described in the literature involving cases that are often initially suspected to be related to inherent structural knee pathology as opposed to a systemic condition or illness.

: The risk for postoperative venous thromboembolism (VTE) is increased in patients aged more than 70 years and in elderly patients presenting with co-morbidities, for example cardiovascular disorders, malignancy or renal insufficiency. Therefore, risk stratification, correction of modifiable risks and sustained perioperative thromboprophylaxis are essential in this patient population. Timing and dosing of pharmacoprophylaxis may be adopted from the non-aged population. Direct oral anti-coagulants are effective and well tolerated in the elderly; statins may not replace pharmacological thromboprophylaxis...

BACKGROUND: Our objective was to examine the relationships between proximal tibial trabecular (epiphyseal and metaphyseal) bone mineral density (BMD) and osteoarthritis (OA)-related pain in patients with severe knee OA. METHODS: The knee was scanned preoperatively using quantitative computed tomography (QCT) in 42 patients undergoing knee arthroplasty. OA severity was classified using radiographic Kellgren-Lawrence scoring and pain was measured using the pain subsection of the Western Ontario and McMaster Universities Arthritis Index (WOMAC)...

Knee osteoarthritis is a painful, disabling condition that disproportionately affects African Americans. Existing arthritis treatments yield small to moderate improvements in pain and have not been effective at reducing racial disparities in the management of pain. The biopsychosocial model of pain and evidence from the positive psychology literature, suggest that increasing positive psychological skills (e.g., gratitude, kindness) could improve pain and functioning and reduce disparities in osteoarthritis pain management...

The aim of the study is to investigate the correlation of serum cartilage oligomeric matrix protein (COMP) levels with articular cartilage damage based on sonographic knee cartilage thickness (KCT) and disease activity in rheumatoid arthritis (RA). A total of 61 RA patients and 27 healthy controls were recruited in this study. Serum samples were obtained from all subjects to determine the serum COMP levels. All subjects had bilateral ultrasound scan of their knees. The KCT was based on the mean of measurements at three sites: the medial condyle, lateral condyle and intercondylar notch...
