Articular cartilage defect
Damage to the smooth cartilage surface covering joint bones, often resulting from trauma or degenerative processes.
Full Definition
An articular cartilage defect refers to localized damage to the hyaline cartilage that covers the surfaces of bones within synovial joints. These defects can result from acute trauma, repetitive microtrauma, osteochondritis dissecans, or degenerative processes. In orthopedic trauma, cartilage defects are particularly concerning as they can lead to post-traumatic arthritis if not properly addressed. Treatment options range from conservative management to various surgical interventions including microfracture, autologous chondrocyte implantation, or osteochondral grafting.
