There is limited information about the orthopaedic health of dressage horses. This study aimed to document the orthopaedic status, lesion distribution, and evolution of injuries in 70 horses undergoing a minimum of five in-depth orthopaedic assessments at six-months’ intervals. Warmblood (70.0%) and Iberian (24.3%) breeds predominated. The median lameness grade at initial examination was 2/5 (interquartile range 2,2; range 0,3). Hypermetria (42.9%) or hypermetria and weakness (12.9%) were observed at the initial examination and did not change over time. Metacarpophalangeal/metatarsophalangeal joint region injuries (osteoarthritis or suspensory branch injury), 58.6%, predominated at the initial examination; there was a high proportion of persistent or recurrent injuries (90%). Metacarpal/metatarsal region pain (predominantly suspensory desmitis) had a high prevalence at all examinations (24.3–41.4%), and a high proportion of recurrent injury (90%). There was an increase in spinal pain comparing the initial and final examinations (McNemar’s <i>p</i> < 0.001); 21.4% of horses with thoracic region pain subsequently developed lumbosacroiliac region pain. Twenty-six (37.1%) increased work level; nineteen (27.1%) remained at the same level, with 37% competing at Intermediate I or II, under 25 international, or Grand Prix at the final examination, compared with 3% at the initial examination. Serial monitoring and targeted treatment may facilitate horses reaching athletic potential.
