What are the most common sites for Osteochondritis Dissecans (OCD) in dogs besides the shoulder?

The most common sites for Osteochondritis Dissecans (OCD) in dogs, apart from the shoulder, are indeed the elbow, stifle, and hock. These joints are frequently affected due to their range of motion and the mechanical stress they endure during a dog's activities.

OCD occurs when the normal process of endochondral ossification is disrupted, leading to avascular necrosis of the subchondral bone. The elbow joint is particularly susceptible in larger breeds, where the abnormal cartilage development can lead to joint pain and dysfunction. The stifle, being a load-bearing joint, is also at risk, as it supports the dog's weight and engages in significant movement. Similarly, the hock, which involves intricate movements in many activities, is another common site where OCD develops.

Understanding the typical locations affected by OCD helps in diagnosing and treating this condition in dogs effectively. Proper medical intervention or surgical management may be necessary to alleviate pain and restore joint function, especially in the most commonly affected joints.
