Nonoperative management as a prerequisite first line treatment is successful in the majority of cases. For example a 55 year old tennis player who falls onto their knee may have a new traumatic focal defect but the preexisting cartilage was degenerative. Chondral injuries include both single focal defects and diffuse damage more characteristic of degenerative joint disease. In general, those that are on the end of the thigh bone, the femur, are the ones that are easiest to treat and have the best outcomes. Large, focal articular cartilage defects of the knee (> 4 cm) can be a source of significant morbidity and often require surgical intervention. A chondral defect refers to damage to the articular cartilage located at the end of bones. 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 patient’s, … of the condition of the overall knee is as important as the assessment of the chondral defect itself. A chondral defect refers to a specific, localized area of damage to the articular cartilage that lines the ends of the bones (like a tile missing in the floor). Description. goal is to replace a cartilage defect in a high weight bearing area with normal autologous cartilage and bone plug (s) from a lower weight bearing area chondrocytes remain viable, bone graft is incorporated into subchondral bone and overlying cartilage layer heals. 1 They also comprise a significant portion of most isolated grade IV articular cartilage defects in the knee joint. Chondral injuries of the knee are lesions of the articular cartilage of the knee joint. A chondral defect usually occurs following an injury such as a blow to the knee or other joints. PRP is an In Office Procedure: PRP comes from your blood. Healthy cartilage in our joints makes it easier to move. Smaller defects in specific locations may be treated with enhanced bone marrow stimulating techniques, autologous chondrocyte implantation (ACI), or osteochondral autograft transfer which may be completed through the arthroscope. Above: Therapist explaining the pathology of the knee condition to the client What are the symptoms of a chondral defect? Prof. Peter Angele: When talking about joint wear, most people think of older patients at least 60 years old who need an artificial knee. Patient- and lesion-specific factors must be identified when evaluating a patient with an articular cartilage defect. Osteochondral Autograft Resurfacing Ideally, defects of the articular cartilage in the knee would be replaced with normal hyaline cartilage. It is a common procedure used to treat patients with full thickness damage to the articular cartilage that goes all the way down to the bone. Microfracture is a surgical technique that has been developed to treat chondral defects, which are damaged areas of articular cartilage of the knee. Chondral Defect Knee Treatment. A nurse draws the needed amount of … A common type of knee injury is damage to the articular cartilage, the smooth substance that covers the ends of the bones and keeps them from rubbing together as you move. - indicated for larger chondral or osteochondral defects (larger than 2 cm); - donor characteristics: - donors should be less than 30 years of age, with the graft harvesting the intact knee within 24 hrs of death; - knee should be stored in RL at 4 deg; - effect of storage and time: Treatment depends upon the size of the osteochondral defect and the condition of the overlying cartilage. These lesions may be found incidentally but also may be a common source of pain and discomfort in the knee. Search key words included the following: knee, articular cartilage, chondral, defect, lesion, athlete, sport(s), treatment, debridement, lavage, chondroplasty, microfracture, autologous chondrocyte implantation (ACI), osteochondral autograft, allograft, mosaicplasty, and osteoarticular transplantation (OATS). This cartilage would withstand years of use and prevent the development of arthritis. This allows us to treat the bone defect without affecting the cartilage. Some people may not experience any symptoms related to these defects for many years. This damage is common and can be caused by sudden injury or the routine wear and tear that comes with aging. A chondral defect is a defect in the articular (hyaline) cartilage at the end of the bones. Traumatic Focal Articular Cartilage Defects (aka traumatic arthropathy, chondral defects) An articular cartilage injury occurs when there is … As the population ages and people live longer — many of them active or overweight — articular cartilage … In the management of large cartilage defects, the two classically utilized cartilage restoration procedures are osteochondral allograft (OCA) … Osteochondral autograft resurfacing offers some hope in achieving this goal. Symptoms of Knee Chondral Defect: Patients with a knee chondral defect may have pain and swelling with activities, or a “noisy knee” . It allows the bones to glide over each other with very little friction. Unfortunately, cartilage has a poor ability to repair itself when injured. Chondral Defects Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. Cartilage does not repair by itself and therefore other treatment is needed. The diagnosis is made with a 3T MRI. The defect may be found on the femoral condyle, tibial plateau, patella, talus, humerus or on other articular surfaces. Chondral defects are damage to the cartilage that covers the ends of the bones in the knee joint. Specific to the knee joint, damage can occur at the distal end of the femur (thigh bone), the proximal tibia (lower leg bone), or the posterior aspect of the patella (knee cap). Articular cartilage enables the knee to tolerate shearing forces and absorb shock and loads up to 20 times the body's weight. The treatment of chondral defects of the knee can depend upon the location and size of the defect. The presence of coexisting knee pathology, such as ongo-ing ligamentous instability, bony malalignment, or complete meniscal deficiency will prevent an environ-ment conducive for cartilage repair.9,11 Any abnor- CHONDRAL DEFECT OF THE KNEE Cartilage is the extremely smooth, shiny white material that coats the ends of the bones in almost all of the joints in our body. Chondral Defect Knee What is a chondral defect or cartilage defect? Osteochondral defect is a broad term that describes the morphological change of a localized gap in the articular cartilage and subchondral bone 5.It is often used synonymously with osteochondral injury/defect and in the pediatric population. Articular (hyaline) cartilage restoration is a prized goal of orthopedic care because the clinical need is urgent and expanding. Terminology. Isolated lesions of cartilage or subchondral bone are not considered an OCD 6.. The study included patients younger than 40 years of age with anterior knee pain and a grade 4 International Cartilage Repair Society patellar chondral defect between 1 and 2.5 cm 2. What is a Chondral Defect? In my practice, however, there's a wide range of other patients with chondral defects requiring treatment. Careful assessment of the underlying pathomechanics is critical for a successful outcome; these include malalignment of the extensor mechanism, trochlear dysplasia, soft … There is also a chapter for conservative treatments options and rehabilitation after cartilage repair. (The colloquial expression “cartilage damage” might also include meniscal tears, which is an altogether separate category of disease.) Damage to the articular cartilage is called a Chondral Defect. Articular cartilage is the coating of the bones and allows for smooth motion between the ends of the bones. Cartilage, or chondral, damage is known as a lesion and can range from a soft spot on the cartilage (Grade I lesion) or a small tear in the top layer to an extensive tear that extends all the way to the bone (Grade IV or \"full-thickness\" lesion). For small-sized defects with intact cartilage, our treatment of choice is Retrograde Drilling of the lesion and filling it with a special bone cement. However, a small subset of patients with persistent pain after adequate rehabilitation will be potential candidates for surgical intervention. Advances in articular cartilage defect management. This Articular Cartilage is incredibly durable and prevents much wear and tear of the bones as the surfaces are repeatedly rubbed together during everyday actions such as walking, running, squatting etc. Chondral defect; Defect of articular cartilage; Disorder of articular cartilage; Disorder of meniscus; ICD-10-CM M24.10 is grouped within Diagnostic Related Group(s) (MS-DRG v 38.0): 564 Other musculoskeletal system and connective tissue diagnoses with mcc; 565 Other musculoskeletal system and connective tissue diagnoses with cc Chondral defects of the patellofemoral joint are the most common type of articular cartilage defect found in the knee.
