Trochlear dysplasia is an anatomic anomaly of the knee that is characterized by an abnormal geometry of the trochlea. The normal shape of the trochlea is concave, but when the trochlea is flat, the patient may experience knee pain, instability and a higher ...
Articular cartilage plays important roles in weight-bearing, lubrication, and load distribution in articulating joints. The tissue is mostly extracellular matrix (>90% by volume) that is synthesized and remodeled by cells (chondrocytes) embedded within. Ad ...
Chondrocytes depend upon solute transport within the avascular extracellular matrix of adult articular cartilage for many of their biological activities. Alterations to bioactive solute transport may, therefore, represent a mechanism by which cartilage com ...
Micro Proton Induced X-ray Emission (mu-PIXE) analysis has been employed herein in investigating and quantifying the distribution of a number of essential elements in thin human diseased articular cartilage sections affected by osteoarthritis (OA). Various ...
Synoyial joints articulate in a lubricating environment, the system providing for smooth articulation. The articular cartilage overlying the bone consists of a network of collagen fibres. This network is essential to cartilage integrity, suffering damage i ...
The zone of calcified cartilage (ZCC) is critical for the normal attachment of articular cartilage to bone as well as to the biomimetic bioengineering of osteochondral tissue constructs. However, relatively few osteochondral tissue engineering approaches h ...
Injuries to the meniscus are often treated by partial or total meniscectomy, which is known to be associated with detrimental changes in joint function, ultimately increasing the risk of early degenerative joint diseases. Surgical approaches currently in u ...
Osteoarthritis (OA) is one of the most common causes of pain and disability. Currently, non-surgical treatment is limited to analgesic and anti-inflammatory drugs, which are not capable of either modifying the disease process or regenerate damaged parts in ...
The extracellular matrix of dense, avascular tissues presents a barrier to entry for polymer-based therapeutics, such as drugs encapsulated within polymeric particles. Here, we present an approach by which polymer nanoparticles, suffciently small to enter ...
