Abstract
Articular cartilage is a resilient structure that absorbs mechanical
shock and weight bearing stress applied on it. Articular hyaline cartilage
is formed of cells called chondrocytes and a matrix rich in proteoglycan
and collagen.
Chondral defect can be assessed by clinical examination, plain x
ray, MRI and diagnostic arthroscopy to determine the number, size,
location and depth of the defect. The lesions range from small partial
thickness lesions to large full thickness articular defects.
Human articular cartilage has limited repair potential and poses a
great clinical challenge. The treatment of articular cartilage defects
depends on characters of these defects, it may be conservative in the form
of symptomatic treatment, however the surgical treatment provides
definitive treatment.
