Prognosis

  • Depends on the amount of cartilage and bone loss (grading of lesion), with a decrease in cases where there is extensive loss of subchondral bone and, to a less degree, with cartilage loss. The site and number of fragments are also important.
  • The type of horse; what work it does; how early in the pathogenesis of the lesion has surgery been elected; adherence to post-operative protocols; individual trainers and their routines; and owner wishes can all affect the long-term prognosis.
