What's new in the treatment of focal chondral defects of the knee?

چکیده
Articular cartilage injuries in the knee have been recognized as a cause of significant morbidity and disability since the early 19th century.1 Each year it is estimated that chondral lesions affect up to 900,000 individuals in the United States resulting in over 200,000 surgical procedures, most of which are diagnostic arthroscopies and simple debridements.2 The use of arthroscopic techniques has enhanced the ability to detect and determine the extent of isolated or combined cartilage injuries following ligament tears or articular fractures. While it is generally accepted that focal chondral lesions often progress towards osteoarthritis, a review of the literature presents compelling evidence that between 11% and 40% of all patients aged <40 years undergoing arthroscopic surgery for other reasons have treatable chondral injuries that will remain unaddressed.3-5 Chondral and osteochondral restoration treatment techniques are relatively new and rapidly evolving, and represent a tremendous potential to restore functionality in predominantly younger patients. The treatment algorithms for these injuries are complex and often involve multiple procedures such as marrow stimulation, cell transplantation, osteochondral grafting, and bony corrections such as osteotomies.

Treatment of articular cartilage defects of the knee with autologous chondrocyte implantation.
The treatment of focal full thickness articular defects in the knee has continued to present a challenge, with no traditional treatment method providing consistent acceptable long-term clinical results. Patients with significant chondral defects frequently have persistent joint line pain, swelling, and catching in the knee. In contrast to marrow stimulation treatment techniques, such as abrasio...
متن کاملFailure of Bone Marrow Stimulation Techniques.
Marrow stimulation techniques, including microfracture, are among the most commonly performed cartilage restoration procedures for symptomatic chondral defects of the knee. For the vast majority of patients, marrow stimulation results in reduced pain and improved function, providing overall satisfactory outcomes. In some cases, however, marrow stimulation fails, resulting in symptom recurrence ...
متن کاملMultiple Osteochondral Allograft Transplantation with Concomitant Tibial Tubercle Osteotomy for Multifocal Chondral Disease of the Knee
Symptomatic patellofemoral chondral lesions are a challenging clinical entity, as these defects may result from persistent lateral patellar maltracking or repetitive microtrauma. Anteromedializing tibial tubercle osteotomy has been shown to be an effective strategy for primary and adjunctive treatment of focal or diffuse patellofemoral disease to improve the biomechanical loading environment. S...
متن کاملOsteochondral Autografts and Allografts in the Treatment of Focal Articular Cartilage Lesions
Focal chondral defects of the knee, either due to trauma or other conditions such as osteochondritis dissecans, often fail to heal on their own and may be associated with pain, loss of function, disability, and the long-term complication of osteoarthritis. The ideal resurfacing technique would eliminate symptoms, restore normal biomechanics of the knee joint, and prevent the long-term emergence...
