Summary
Bone marrow lesions (BMLs) impact joint health through altered subchondral bone remodeling. A new "Two Pillar" concept highlights subchondral bone
Area of Science:
- Orthopedics and Sports Medicine
- Radiology
- Biomedical Engineering
Background:
- Bone marrow lesions (BMLs) are common MRI findings with unclear causes and effects on disease progression.
- Subchondral bone is crucial for joint health, actively remodeling to meet mechanical and biological demands.
- Altered bone remodeling in BMLs can impair joint tissues and overall joint function.
Purpose of the Study:
- To review the etiology, pathogenesis, and clinical presentation of BMLs.
- To introduce and discuss the novel
- Two Pillar
- concept.
- To correlate BML knowledge with current and future treatment strategies.
Main Methods:
- Literature review of BMLs, subchondral bone biology, and cartilage changes.
- Synthesis of existing research to propose the
- Two Pillar
- concept.
- Correlation of BML characteristics with therapeutic interventions.
Main Results:
- BMLs are linked to significant alterations in subchondral bone remodeling.
- A strong association exists between subchondral bone's biological and structural status and overlying cartilage health.
- The
- Two Pillar
- concept posits subchondral bone as foundational for articular cartilage structure and function.
Conclusions:
- Subchondral bone's structure and biology are critical determinants of articular cartilage integrity.
- Understanding BMLs through the
- Two Pillar
- concept offers new perspectives on joint disease.
- This framework may guide the development of targeted treatments for BMLs and related joint pathologies.

01:55Bone Structure
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.
01:23Bone as Supporting Connective Tissue
Bone tissue forms the internal skeleton of vertebrate animals, providing structure to the body.
Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts— that give the...

01:26Bone Markings
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

01:30Bone Cells and Tissue
Bones contain a relatively small number of cells entrenched in a matrix of organic and inorganic components. Although bone cells compose only a small amount of the bone volume, they are crucial to its function. Four types of cells are found within the bone tissue— osteoblasts, osteocytes, osteogenic cells, and osteoclasts.
Osteoblasts and Osteocytes
The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the periosteum and...

01:29Blood and Nerve Supply to the Bones
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

01:22Bone Marrow Sampling and Transplants
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy the...
