Bone marrow lesions of the knee in patients with osteoarthritis (OA-BML) are an important clinical entity that may explain progressive pain, decreased quality of life, and impaired function. MRI of OA-BMLs demonstrates a region of subchondral bone with hyperintense marrow signal on T2-weighted images. Histopathology retrieval studies have demonstrated that these lesions correlate with microdamage of the trabecular bone, and subsequently, this leads to a vicious cycle of subchondral bone attrition, attempts at repair, pain, and progressive deformity. These lesions have also been linked to accelerated loss of adjacent articular cartilage and increases in the severity of knee pain, prompting patients to seek musculoskeletal care and treatment. Multiple studies have also correlated the presence of an OA-BML with an increased probability of seeking knee arthroplasty. Knowledge of these lesions is important in the context that knee OA is both a cartilage-based and bone-based disease. Further study of OA-BMLs may provide opportunities for early intervention and OA disease-modifying treatments.

Does MRI of Knee Cartilage Help to Characterize Osteoarthritis Severity?: Commentary on an article by Joshua S. Everhart, MD, MPH, et al.: "Full-Thickness Cartilage Defects Are Important Independent Predictive Factors for Progression to Total Knee Arthroplasty in Older Adults with Minimal to Moderate Osteoarthritis. Data from the Osteoarthritis Initiative".
This review summarizes what is known about how bone tissue responds to microdamage, and how this applies to the subchondral region. This has significant relevance to acute joint injury, and is related...
Bone fractures are a common cause of hospital admission. Currently, treatment consists of conservative regimens or operation. However, regenerative medicine introduces a possible new addition to estab...
Crepitus is a common clinical feature of knee osteoarthritis. However, the importance of crepitus in the overall clinical presentation of individuals with knee osteoarthritis is unknown.
To assess the ability of radiography-based bone texture variables in proximal femur and acetabulum to predict incident radiographic hip osteoarthritis (rHOA) over a 10 years period.
The purpose of the study is to investigate the density, architecture, and perfusion of bone marrow lesions (BMLs) in knee osteoarthritis. We will perform MRI's and QCT's on subjects prior ...
This pilot study will evaluate the clinica! and radiological results of a treatment for knee osteoarthritis with injections of autologous concentrated bone marrow aspirate at the bone-cart...
This study is intended to compare whether bone marrow aspirate concentrate or platelet rich plasma injections is more effective in treating knee osteoarthritis.
The Clinical trial is a phase I/IIa clinical study for treatment of knee osteoarthritis by intra-articular injection of bone marrow derived allogeneic mesenchymal stem cells. Primary endpo...
Patients with osteoarthritis of the knee undergo visible joint changes in radiology and Magnetic resonance imaging (MRI) tests, but also clinically and histologically. The area of greatest...
Neoplasms located in the bone marrow. They are differentiated from neoplasms composed of bone marrow cells, such as MULTIPLE MYELOMA. Most bone marrow neoplasms are metastatic.
Techniques for the removal of subpopulations of cells (usually residual tumor cells) from the bone marrow ex vivo before it is infused. The purging is achieved by a variety of agents including pharmacologic agents, biophysical agents (laser photoirradiation or radioisotopes) and immunologic agents. Bone marrow purging is used in both autologous and allogeneic BONE MARROW TRANSPLANTATION.
The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.
Noninflammatory degenerative disease of the knee joint consisting of three large categories: conditions that block normal synchronous movement, conditions that produce abnormal pathways of motion, and conditions that cause stress concentration resulting in changes to articular cartilage.

Removal of bone marrow and evaluation of its histologic picture.
Arthritis is by definition the inflammation of one or more joints, characterized by swelling, pain, warmth, redness and diminished range of joint movement (Oxford Medical Dictionary). There are many different types; Noninflammatory; Osteoarthritis, N...
Osteoporosis is a disease in which the bones become extremely porous, are subject to fracture, and heal slowly, occurring especially in women following menopause and often leading to curvature of the spine from vertebral collapse. Follow and track&n...
A joint is where two or more bones come together, like the knee, hip, elbow, or shoulder. Joints can be damaged by many types of injuries or diseases, including Arthritis - inflammation of a joint causes pain, stiffness, and swelling with ...
