ADVERTISEMENT: Supporters see fewer/no ads. Eur J Radiol Open. The most commonly performed procedures for treating chondral defects include chondroplasty (cartilage removal), microfracture (holes made in bones that release stem cells from the marrow), and OATS, or OsteoArticular Transfer this can be done by taking a piece of bone and cartilage from elsewhere in ones knee or from a cadaver knee and then transplanting it into the defective area. In addition moving around with a torn meniscus could pull fragments of the cartilage into the joint causing larger knee issues which could requiring more significant surgery in the future.

Knee instability knee buckling, giving way, giving out, the knee is unable to support your weight. Interactions between severity and location of chondral lesions and meniscal tears found at arthroscopy. sharing sensitive information, make sure youre on a federal Small pieces of the articular cartilage can break off and float around in the knee as loose bodies, causing locking, catching and/or swelling. I have looked many times for answers on my tibial tubercle osteotomy and never found any as detailed as i needed. The treatment for chondral injurys ranges from conservative, to arthroscopic and open surgeries (arthroscopic debridement, marrow-stimulating techniques, autologous chondrocyte transfers and implantation, and allografts), and would depend on the patients, age, etiology, grade, and quality of the lesion. The ends of the femur and tibia, the knee bones, are capped with a gristle which is called cartilage. In these circumstances, there may not be any large cartilage flaps demonstrated on the MRI scan and there may just be softening of the cartilage surface. For those patients who have very deep cartilage defects, which extend all the way down to bone, the treatment of these can depend upon the location and overall diameter of the defect. Those on the tibia and kneecap (patella) are harder to treat and the results are not as reliable. 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. Grade I - The cartilage "blisters" and becomes soft in the earliest form of damage. (Please keep reading below for more information on this condition.).

The fact that we rely on motion of the opposing surface to provide nourishment for cartilage is the principle behind early motion after cartilage surgeries and the use of a continuous passive motion machine (CPM). Orthopedics. During knee arthroscopy, a thin fiberoptic light, magnifying lens and tiny television camera are inserted into the knee, allowing your doctor to examine the joint in great detail. Factors that influence the choice of procedure include: The most commonly performed procedures for treating chondral defects are Shaving and Microfracture.
