Which species shows a better prognosis for stifle or tarsal OCD after surgery?

• A. Horses.
• B. Dogs.
• C. Both equally.
• D. Neither.

Answer: (A)

The main idea is that prognosis after surgical treatment for OCD in the stifle or tarsus varies by species, with horses generally having the better outcome. In horses, OCD lesions in these joints are often focal cartilage flaps or osteochondral fragments that can be effectively removed or debulked arthroscopically. When the joint surface is restored, the remaining cartilage has a good chance to remodel, and with proper post-operative rehab, many horses return to athletic function, giving a favorable prognosis. In dogs, OCD lesions in these joints tend to involve broader areas of cartilage and subchondral bone, and even after surgery there is a higher risk of persistent joint incongruity and progression to osteoarthritis. This makes long-term function more variable and often less favorable compared to horses. So, horses show a better prognosis after surgery for stifle or tarsal OCD.
