However, acute traumatic osteochondral lesions or surgically created lesions extending into subchondral bone, e.g. by Pridie drilling, [2] spongialization [3] abrasion [4] or microfracture causing the release of multipotent mesenchymal stem cells from the bone marrow, may heal with repair tissue consisting of fibrous tissue, fibrocartilage or ...
Medical condition Osteochondritis dissecans A large flap lesion in the femur head typical of late stage Osteochondritis dissecans. In this case, the lesion was caused by avascular necrosis of the bone just under the cartilage.

When the damage increases and the chondral defect reaches the subchondral bone, the blood supply in the bone starts a healing process in the defect. Scar tissue made up of a type of cartilage called fibrocartilage is then formed. Although fibrocartilage is able to fill in articular cartilage defects, its structure is significantly different ...
An osteochondrodysplasia, [note 1] or skeletal dysplasia, is a disorder of the development of bone and cartilage. [1] Osteochondrodysplasias are rare diseases.About 1 in 5,000 babies are born with some type of skeletal dysplasia. [2]
Articular cartilage, most notably that which is found in the knee joint, is generally characterized by very low friction, high wear resistance, and poor regenerative qualities. It is responsible for much of the compressive resistance and load bearing qualities of the knee joint and, without it, walking is painful to impossible.
By doing this, the subchondral bone is perforated to generate a blood clot within the defect. Studies, however, have shown that marrow stimulation techniques often have insufficiently filled the chondral defect and the repair material is often fibrocartilage (which is not as good mechanically as hyaline cartilage). The blood clot takes about 8 ...
Though articular cartilage damage is not life-threatening, it does strongly affect the quality of life. Articular cartilage damage is often the cause of severe pain, swellings, strong barriers to mobility and severe restrictions to the patient's activities.
In dogs osteochondrosis is seen in elbow, shoulder, knee, and ankle joints. Elbow osteochondrosis is also known as "elbow dysplasia". There are three types of elbow dysplasia: fragmented medial coronoid process, ununited anconeal process and Osteochondritis dissecans of the medial humeral condyle.
