This is a sentinel sign that we rely on for those patients that are symptomatic. The patient's articular cartilage cells are arthroscopically removed from the injured knee and grown outside the body in tissue culture. The symptoms of a chondral injury are not as obvious as those of a meniscus tear or ligament injury. A person with cartilage damage should avoid high impact activities, such as prolonged running or jumping sports. Return to sports often takes 6 - 12 months. Most studies of the effects of glucosamine and chondroitin have been done in animals, and most of the reported effects are based on hearsay rather than scientific evidence. Imaging using an X-ray, MRI or via an arthroscopic examination can help determine if cartilage loss is occurring, thus leaving a decrease in space between the bone surfaces. 4. This procedure is best for defects smaller than 15-20mm in size because there is a limit to the number of plugs that can be harvested. The grade of injury depends on the size of the involved area and how much of the cartilage thickness is worn down. For deeper or larger cartilage defects, one of the more reliable techniques in indicated patients is a fresh osteoarticular allograft. This is a well-accepted technique that is a common procedure for patients with damage through the full thickness of articular cartilage, all the way down to the bone. Dull, aching pain and/or a feeling of grinding when the knee is flexed may occur. OATS, osteochondral autograft transfer system, is a technique that involves replacing damaged joint cartilage (in high weight bearing areas) with healthy cartilage and bone (from lower weight bearing areas). The pain often is worse during twisting or squatting motions. Pain results when the knee and the thigh bone (femur) rub together. Chondral fissures are a type of chondral injury more accurately cracks or crevices of cartilage extending from the articular surface to the deeper chondral layers.

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. Full activity resumes in 3 - 6 months, depending on the size of the cartilage damage. Microfracture In this procedure, a tiny fiberoptic scope is inserted into the joint. (It is also recommended to treat many acute injuries.). Thisarthroscopic surgerytechnique uses special arthroscopic instruments to smooth the shredded or frayed articular cartilage.

Viewed by the naked eye, it has a glistening, white appearance. Treatment for osteoarthritis initially focuses on relieving pain and other symptoms, and may include rest, physical therapy, bracing and anti-inflammatory medication. 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 . What are the most important things a person can do to limit chondral or cartilage damage in the knee? Current surgical options for articular cartilage repair.
