Cause: Ischemia
Ischemia occurs when there is a decrease in blood supply to a specific part of the body. Although commonly associated with insufficient blood flow to the heart, it can also affect joints and cartilage, particularly following an injury. In cases where there is inadequate blood flow to a portion of the cartilage, it can result in atrophy and fragmentation of the cartilage or underlying bone, leading to a condition known as OCD (osteochondritis dissecans). The compromised bone structure due to necrosis increases the risk of fractures.
Cause: Genetic Factors
Genetic factors play a significant role in the development of osteochondritis dissecans (OCD). Certain families may have a higher susceptibility to this condition, as it tends to affect more than one family member. This could be due to the genetic component related to the positioning of small blood vessels around the joints. Although the specific genetic markers for OCD are not yet identified, individuals with a family history of this condition should exercise caution when participating in sports or engaging in strenuous physical activities.
