SYNOVIUM, LEFT KNEE, BIOPSY: - SYNOVIUM WITH MILD CHRONIC INFLAMMATION AND VILLOUS HYPERPLASIA -- COMPATIBLE WITH OSTEOARTHRITIS The synovium is a specialized connective tissue that lines diarthrodial joints, surrounds tendons and forms the lining of bursae and fat pads. In synovial joints, the synovium seals the synovial cavity and fluid from surrounding tissues Either no prior arthritis (primary or idiopathic OA) or due to severe arthritis (secondary OA) Usually age 50+ years (present in 80% at age 65 years) Symptoms: pain worse with use of joint, crepitus, limited range of motion, nerve root compression; Heberden nodes in fingers of women only (osteophytes at DIP joints) Secondary degenerative joint.

The synovium is one of the major target tissues of RA and SpA, the two most prevalent types of chronic inflammatory joint diseases, and the availability of synovial tissue collected in different disease phases provides a unique opportunity to study the cellular and molecular pathways driving chronic joint inflammation Histology and metabolism of the articular cartilage The connecting unit between bone ends and the surrounding soft tissue, the cartilage, the ligaments and the synovium is a functional unit, and the cartilage represents the center of the functional unit. In a classical synovial joint, bone ends are covered by hyaline cartilage Fibrosis of the synovium occurs in most arthropathies and may be indicative of epithelial to mesenchymal transitions in resident fibroblasts leading to increased extracellular matrix (ECM) deposition Synovium is specialized mesenchymal tissue that is essential for the appropriate function of the locomotor apparatus. It is the site for a series of pathologic processes that are characteristic, and in some cases specific, to this distinctive tissue. In this article, the normal microscopic anatomy of synovium is briefly reviewed

Studies have shown that changes in the synovium are a very early and integral part of osteoarthritis Synovitis is a major characteristic of chronic inflammatory joint diseases of autoimmune origin, such as rheumatoid arthritis (RA) and spondyloarthropathy (SpA). It can also occur as a secondary inflammatory symptom in osteoarthritis (OA), which is primarily induced by biomechanical stress on cartilage and subchondral bone Synovial Histology. Despite a long history of categorizing OA as a non-inflammatory form of arthritis, pathologic studies of SM specimens dating back to the 1980s described synovial inflammatory infiltrates of mononuclear cells, which in some cases were indistinguishable from infiltration observed in rheumatoid arthritis (RA) (36, 61, 81).It was assumed that synovitis in OA occurred primarily. Failure of conventional anti-inflammatory therapies in osteoarthritis (OA) underlines the insufficient knowledge about inflammatory mechanisms, patterns and their relationship with cartilage degradation. Considering non-linear nature of cartilage loss in OA, a better understanding of inflammatory milieu and MMP status at different stages of OA is required to design early-stage therapies or. The synovium is a loose connective tissue that encapsulates the joint and aids in maintaining joint homeostasis through the functions of its resident cells: synovial macrophages and the more abundant FLS [reviewed in (3, 4)]

Pigmented villonodular synovitis is an uncommon disease characterized by hyperplastic synovium, large effusions and bone erosions. The disease was first described as a distinct entity in 1941.1. With Osteoarthritis, we're really talking about one particular kind of joint which is a synovial joint. Along with articular cartilage , another important component of synovial joints , and where they get their name from, is the synovium, which along with the surface of the articular cartilage , forms the inner lining of the joint space Osteoarthritis can occur in both synovial and cartilaginous joints but is much more commonly diagnosed in the synovial joints of the leg. The synovial joint is composed of various connective tissues (bone, articular cartilage, joint capsule, surrounding soft tissues), each of which contribute to normal function of the healthy joint Read The Human Fetal Synovium.

Background/Purpose: To better understand site-of-disease mechanisms in arthritis, the phenotypes and organization of synovial cells and infiltrates are critical. Conventional histology-based approaches are limited in the number of proteins that can be detected and quantification can be difficult due to non-linear detection systems. Tissue disaggregation techniques have advantages for some. Mobilization of mesenchymal stem cells (MSCs) from the synovium was revealed using a suspended synovium culture model of osteoarthritis (OA). The pathology of rheumatoid arthritis (RA) differs from that of OA. We investigated whether mobilization of MSCs from the synovium also occurred in RA, and we compared the properties of synovial MSCs collected from suspended synovium culture models. Subintimal area of synovium: This is where the synovial blood vessels are located; this area normally has very few cells. In RA, however, the subintimal area is heavily infiltrated with inflammatory cells, including T and B lymphocytes, macrophages, mast cells, and mononuclear cells that differentiate into multinucleated osteoclasts macrophages as potential target cells for treatment of OA pathology.

The synovium controls transport of solutes in and out of the joint, and contains cells that produce lubricating agents, as well as stem cells that can participate in joint repair after injury. In the case of arthritis, the synovium releases pro inflammatory cytokines into the joint space that triggers enzymatic degradation of articular cartilage Introduction. Osteoarthritis (OA) is a chronic joint disease characterized mainly by degeneration of articular cartilage. However, as research has progressed, the synovium and subchondral bone have been shown to play an important role in the pathological process of OA, and the perspective on OA is changing from a disease involving cartilage only to a disease of the entire joint [] Knee osteoarthritis is degenerative disease of the knee joint that causes progressive loss of articular cartilage. mild inflammatory changes in synovium. middle phase of OA. moderate inflammatory changes of synovium.
