Cartilage thinning or loss is also usually visible on MRI. Chondral delamination ( Figure 1) is defined as the separation of articular cartilage from the underlying subchondral bone. Hyaluronic acid works as a lubricant and cushion in the joints and other tissues, affecting the weight-bearing ability and the bodys response to injury. Once it is damaged, articular cartilage is unable to repair itself. [Surgery on articular cartilage: from debridement to tissue engineering]. Damage may also be the result of a direct blow to the knee. This . Ideally, these cells will fill the defect with a new cartilage surface over time. We have used ACI on defectsover 20 cm2, with outcomes similar to more usual-sized defects. Cartilage is composed of primarily type II collagen, and a large portion of it is water.

Treatment is designed to relieve pain, improve knee function and delay the requirement of knee replacement surgery. Chondral delamination is the separation of the articular cartilage from the underlying subchondral bone at the tidemark [].These injuries have been reported as the result of shearing stress that is concentrated at the junction of the noncalcified and calcified cartilage [1-3].The delamination line runs parallel to the joint surface, but the overlying articular cartilage remains initially . For patients who choose not to want surgery and who have more extensive chondromalacia, the use of an unloader brace to take the stress off a malaligned joint which has the weightbearing fall through the cartilage defect, or the use of further injections, such as viscosupplementation with hyaluronic acid or PRP may be indicated. Both operative and nonoperative treatments may be indicated. An articular cartilage injury, or chondral injury, may occur as a result of a pivot or twist on a bent knee, similar to the motion that can cause a meniscus tear. Let us live f twitter.com/i/web/status/1, Riley J. Williams III, M.D. Articular cartilage is found at the ends of bones which are in a joint. Chondromalacia is "softening" of the articular cartilage, with varying degrees of depth and severity of involvement. This layer is important to ensure that the cartilage does not shear off, or fissure, when one participates in twisting, turning, or pivoting type activities.
