Videoendoscopic arthroscopic surgery is a minimally invasive option to explore and correct abnormalities of a horse’s joints and tendon sheaths. The same technique is commonly used in human knee surgeries and greatly speeds recovery compared to traditional surgical methods. Horses are anesthetized for this surgery, and a small camera called an arthroscope is inserted into the joint space and used to visualize the joint’s surfaces and structures. We can treat equine osteochondrosis lesions (OCD) by inserting instruments through a second tiny incision called a portal. We can also use arthroscopy to remove infected tissue or traumatic bone chips from joints. The most treated areas include knees (carpi), hocks, and stifles.
