Articular Cartilage Damage With Intramedullary Les..

Cartilage damage is a relatively common type of injury. In adults, the articular cartilage matrix is separated from the subchondral vascular spaces by the subchondral plate. Nutrition of the articular cartilage occurs by simply diffusion from the synovial fluid. The cartilage matrix restricts materials by size, charge, and molecular settings It is estimated that the average pore size within the ECM is approximately 6. 0 nm. 30, 33, 46 Without a direct availability of nutrition from blood vessels or perhaps lymphatics, chondrocytes depend mainly on anaerobic metabolism.
Depending on the depth, articular cartilage defect is classified as chondral or osteochondral. The real chondral defect is even more divided into a complete width, i. e. down to subchondral bone or an incomplete thickness or a flap of cartilage 5 (Fig. 2 E). These defects embrace size and range and don’t repair on their particular own. 5, 11, 18 Result of repair will depend on whether the injury expands into the subchondral vascular bone marrow. Osteochondral defect includes a full thickness the cartilage defect extending into the underlying subchondral bone (Fig. 2 F). Thus, osteochondral defect crosses the tidemark, making means for the bone marrow mesenchymal progenitor cellular material into the defect. This leads to the development of a fibrocartilage type of repair. Hence, depth of the defect is definitely crucial for stimulating a repair response.

Direct physical trauma to the matrix, without damaging the cells: In this situation, in the event the loss of matrix components does not exceed the ability of chondrocytes to synthesize new proteoglycan molecules, cartilage will probably be refurbished.
Articular cartilage lesions are defined as a collective term of injuries in which the articular cartilage of the knee joint is affected. Only arthroscopic evaluation allows exact determination of defect size and quality and it is essential in terms of differential diagnosis and classification of a cartilage lesion using the Outerbridge Classification.cartilage spiral sticks
Abrasion arthroplasty: This procedure is similar to drilling but involves employ of high-speed burs to remove the damaged cartilage.
