We report outcomes of arthroscopic surgery in 30 Arabian, mixed and thoroughbred racehorses 1 to 9 years old with joint fragments caused by osteochondritis dissecans or trauma over 2 years. Carpus were most affected by chip fracture and stifle joints by osteochondritis dissecans. Horses scored 2-3/5 lameness mostly in 3-4 year old males (53.33%) with carpal (51.21%) in single 66% or multiple joints (33%). We found arthritis in two (6.66%) after surgery, but 25 horses (83.33%) recovered completely and those with one joint injury had best outcomes.
