This is the first study to investigate the usefulness of a standardized ultrasound (US) examination protocol in diagnosing hand osteoarthritis (OA). We conducted a cross-sectional study including 62 patients, ultimately diagnosed with hand OA based on imaging evidence of osteoarthritic changes with the particular distribution required for fulfilment of American College of Radiology diagnosis criteria. We compared a 32-joint US score (wrists, metacarpophalangeal [MCP], proximal interphalangeal [PIP] or distal interphalangeal [DIP] and carpometacarpal [CMC]-1 joints), with smaller, predefined joint scores, assessing 22 joints (wrists, MCPs and PIPs or PIPs, DIPs and CMC-1), 10 joints (MCP 2-3, PIP 2-3 and CMC-1 or PIP 2-3, DIP 2-3 and CMC-1) and 6 joints (DIP 2-3, CMC-1), respectively...

Osteoarthritis (OA) is a whole-joint disorder, and non-cartilage articular pathologies, e.g. subchondral bone disturbance, contribute substantially to the onset and progression of the disease. In the early stage of OA, abnormal mechanical loading leads to micro-cracks or micro-fractures that trigger a reparative process with angiogenesis and inflammatory response. With the progression of disease, cystic lesion, sclerosis and osteophytosis occur at tissue level, and osteoblast dysfunction at cellular level. Osteoblasts derived from OA sclerotic bone produce increased amount of type I collagen with aberrant Col1A1/A2 ratio and poor mineralization capability...

CASE: Hemiarthroplasty of the shoulder is commonly indicated for younger patients with osteoarthritis who desire to continue recreational and employment activities. In patients who have undergone prior shoulder surgery, metallic suture anchors may be present in the glenoid. We present a case of bilateral shoulder metallosis following bilateral resurfacing hemiarthroplasty for arthropathy in the setting of previous shoulder instability; the prostheses caused eventual glenoid erosion, leading to contact with the retained metal anchors...

Here, we show the role of melatonin combined with or without exercise as a determinant of multicellular behavior in osteoarthritis. We address the relationship between the molecular components governing local circadian clock and changes in the osteoarthritic musculoskeletal axis. Melatonin was injected subcutaneously in animals with advanced knee osteoarthritis (OA) for 4 weeks. Concurrently, moderate treadmill exercise was applied for 30 min/day. Morphometric, histological, and gene/protein-level analyses were performed in the cartilage, synovium, bone, and gastrocnemius muscle...

BACKGROUND: Osteoarthritis (OA) is now increasingly recognized as being related to the whole joint instead of the cartilage alone. In particular, the importance of subchondral bone in OA pathogenesis has drawn a lot of interest. The aim of this study is to investigate subchondral bone microstructural features in two femoral condyles of human knee osteoarthritis. METHODS: Eighty subjects were enrolled in our study and divided into three groups: without OA (group 0), mild OA (group 1), and severe OA (group 2)...

Due to the inconsistent association between high-sensitivity C-reactive protein (hs-CRP) and osteoarthritis (OA), we evaluated the relationship between hs-CRP and various radiographic findings in older adults with OA. This cross-sectional study recruited 2376 participants from the population-based Dong-gu cohort. The scores of radiographic features in OA on X-rays of the knees and hands were computed using a semi-quantitative grading system. The hs-CRP levels were measured using a particle-enhanced immunonephelometry assay...

The TAM receptor tyrosine kinases (TAM RTK) are a subfamily of receptor tyrosine kinases, the role of which in autoimmune diseases such as systemic lupus erythematosus has been well explored, while their functions in rheumatoid arthritis (RA) remain largely unknown. In this study, we investigated the role of soluble TAM receptor tyrosine kinases (sAxl/sMer/sTyro3) in patients with RA. A total of 306 RA patients, 100 osteoarthritis (OA) patients and 120 healthy controls (HCs) were enrolled into this study. The serum concentrations of sAxl/sMer/sTyro3 were measured by enzyme-linked immunosorbent assay (ELISA), then the associations between sAxl/sMer/sTyro3 levels and clinical features of RA patients were analysed...

Hand osteoarthritis (OA) is a common degenerative joint disorder leading to substantial pain and disability. The most severe subtype is erosive hand OA characterized by an abrupt onset, local inflammation, subchondral erosions and worse outcomes than non-erosive disease. Biomarkers of hand OA could help to diagnose the disease earlier, to distinguish patients with erosive and non-erosive forms, to assess disease severity or to predict its future progression. The objective of this review was to summarize the role of potential biomarkers of hand OA...

The effect of scopoletin-standardized Morinda elliptica leaf extract against osteoarthritis was investigated in ex vivo explant culture and preclinical rodent model. Thirty male rats were grouped (n = 6) into untreated osteoarthritis (OA), OA + Diclofenac (5 mg/kg), and OA + extract (200 and 400 mg/kg) and compared with healthy control. Monosodium iodoacetate were injected into the right intra-articular knee joints to induce OA. The rats were evaluated for OA severity via physical (micro-CT and histological observations), biochemical, ELISA, and mRNA expression analysis (for inflammation and cartilage degradation biomarkers), after 28 days of treatment...

REVIEW
Peter Domos, Caio Santos Checchia, Gilles Walch
The management of primary osteoarthritis of the shoulder has been well investigated. However, the etiology and management of posterior humeral head subluxation in the context of primary glenohumeral osteoarthritis remain controversial. The finding of static posterior subluxation of the humeral head before the development of posterior bone erosion of the glenoid in young men with radiographic findings of primary osteoarthritis has been described as arthrogenic posterior subluxation of the humeral head. It demonstrates the earliest form of the osteoarthritic evolution, and an excessive glenoid retroversion is the only probable cause of this static subluxation, although this is controversial...

Osteoarthritis induced by compressive mechanical force is characterized by decreased chondrocyte proliferation and degradation of the ECM. To examine underlying mechanisms of the pathological changes of mandibular cartilage induced by compressive mechanical force, an established animal model was used to examine Wnt signaling activation by glycogen synthase kinase-3 beta (GSK3β) inhibitor 6-Bromoindirubin-3'-oxime (BIO) injection in vivo. Histological changes in mandibular cartilage were assessed via hematoxylin & eosin (HE), masson, and alcian blue staining...

Osteoarthritis (OA) is the most common form of joint disease and is widespread in the elderly population and is characterized by erosion of articular cartilage, subchondral bone sclerosis and synovitis. Oleuropein (OL), a secoiridoid, is considered as the most prevalent phenolic component in olive leaves and seeds, pulp and peel of unripe olives and has been shown to have potent anti-inflammatory effects. However, its effects on OA have not been clearly elucidated. This study aimed to assess the effect of OL on human OA chondrocytes...
