Ghasemi S, Sardari K, Mohamadnia A, Alipour F, Mirshahi A, Rajabion M., Outcomes after arthroscopic surgery for osteochondritis dissecans and trauma joint fragment in racehorses, Onl J Vet Res., 26 (8): 593-598, 2022. We report outcomes for arthroscopic surgery for chip fracture of carpus and stifle joints due to osteochondritis dissecans and trauma in 1 to 9 year old male and female arabian, mixed and thoroughbred racehorses over 2 years. We observed grade 2 or 3 lameness mostly in male horses with 53% three to 4 year old carpus and stifle chip fractures. Twenty horses (66%) underwent arthroscopic procedures in a single joint whereas 33% had more than one joint. After surgery we detected arthritis in 2 horses (6.66%), one (3.33%) participated in 4 races. Follow up revealed that 83.33% of horses returned to normal racing. Findings suggest arthroscopic surgery can manage lameness due to osteochodritis dessicans, osteochondral fragments and chip fractures.
