An osteochondral injury is an injury to the smooth surface on the end of bones, called articular cartilage ( chondro), and the bone ( osteo) underneath it. It is an abnormal growth that forms on the surface of a bone near the growth plate. In about 10– 15% of all cases no genomic alterations are detected. Histologically, osteochondrosis is characterized by persistence of chondrocytes in the mid to late hypertrophic zone with failure of vascular invasion and subsequent osteogenesis.
Such lesions are a tear or fracture in the cartilage covering one of the bones in a joint. An osteochondroma is made up of both bone and cartilage. Osteochondrosis is a failure of normal endochondral ossification, resulting in thickening and retention of the hypertrophic zone of the growth cartilage.

The identified mechanism behind solitary osteochondromas is the homozygous deletions of the EXT1 gene. Osteochondral Lesions/ Osteochondritis Dessicans. Osteochondrosis [ os″ te- o- kon- dro´ sis] a disease of the growth ossification centers in children, beginning as a degeneration or necrosis followed by regeneration or recalcification; known by various names, depending on the bone involved.

Osteochondrosis is a family of orthopedic diseases of the joint that occur in children, adolescents and other rapidly growing animals, particularly pigs, horses, dogs, and broiler chickens. Osteochondroma is the most common noncancerous bone growth.
Osteochondral lesions or osteochondritis dessicans can occur in any joint, but are most common in the knee and ankle.
