Osteochondral Defect
A localized injury involving both the articular cartilage and underlying subchondral bone, typically requiring specialized surgical intervention.
Full Definition
An osteochondral defect is a focal lesion that involves damage to both the articular cartilage surface and the underlying subchondral bone within a joint. These defects can result from acute trauma, repetitive stress, osteochondritis dissecans, or degenerative processes. The condition is particularly significant in orthopedic rehabilitation because it affects joint mechanics, load distribution, and long-term joint health. Treatment options range from conservative management to various surgical procedures including microfracture, osteochondral autograft transfer, or cell-based therapies. Rehabilitation protocols must carefully consider the healing characteristics of both cartilage and bone tissue, often requiring prolonged periods of modified weight-bearing and gradual return to high-impact activities.
Usage
Usage note: Specify size, location, and depth when documenting; distinguish from purely chondral lesions.
