Osteochondrosis is a medical condition that refers to the degeneration of bones and cartilage in the joints. It mainly affects young and growing animals, causing significant pain and mobility issues. Other terms used in place of osteochondrosis include OC, osteochondrodysplasia, and dyschondroplasia. Several subtypes of osteochondrosis exist that affect different joints. For instance, osteochondritis dissecans is a type of osteochondrosis that affects the articular cartilage in joints. Several factors can cause osteochondrosis, including genetics, nutritional deficiencies, trauma, and rapid growth. Treatment may involve non-surgical approaches such as rest, exercise, and dietary changes or surgical interventions such as arthroscopy or joint replacement.
