Metacarpal tendon diseases are important problems that may cause a decrease in performance and even may finish sport life in equine athletes. In this study, it was aimed to evaluate the ratio of return to races and the time of staying away from races and also to detect the prognostic value of ultrasonographic findings in Thoroughbred and Arabian racehorses with metacarpal flexor tendon injury or peritendonitis. Of 120 cases, 84 (70.0%) returned to races. Among these, 82.1% had tendonitis (69/84) and 17.9% peritendonitis (15/84). Among the cases being unable to return to races, 91.7% had tendonitis (33/36), and 8.3% had peritendonitis (3/36). Although not statistically significant (P > .05), tendonitis cases were found to be away from races for longer periods. Tendonitis cases (85.0%, 102/120) stayed away from races for an average of 39.9 months, whereas peritendonitis cases (15.0%, 18/120) stayed away from races for an average of 27.1 months. It was found that the ratio of return to races after injury was higher in cases without tendon thickening (86.7%, 26/30) than in cases with tendon thickening (64.4%, 58/90). The results of this study show that tendon injuries causing tendon thickening have a negative effect on the ratio of return to races (P < .05).
•Tendonitis is a big problem that has frustrated the international horse racing industry.•Metacarpal tendon diseases may finish sport career in equine athletes.•Because of long-term high-cost treatment with unfavorable prognosis and increased high recurrence in tendinitis, high economic losses occur.•Prophylactic precautions should be taken in terms of tendonitis in the tendon injuries causing tendon thickening even if there is no primary lesion.
