Topic:Osteoarthritis

Osteoarthritis (OA) in horses is a degenerative joint disease characterized by the progressive deterioration of articular cartilage, subchondral bone changes, and synovial inflammation. This condition can result in pain, reduced mobility, and impaired performance in affected animals. Osteoarthritis is commonly observed in athletic horses due to repetitive joint stress, but it can also occur in older horses as part of the natural aging process. Diagnosis typically involves clinical examination, imaging techniques such as radiography or MRI, and sometimes synovial fluid analysis. Management strategies focus on alleviating pain, reducing inflammation, and slowing disease progression through pharmacological treatments, physical therapy, and sometimes surgical interventions. This page compiles peer-reviewed research studies and scholarly articles that explore the pathophysiology, diagnosis, and management of osteoarthritis in equine patients.

Detection of experimental cartilage damage with acoustic emissions technique: An in vitro equine study.
   September 23, 2026  
In horses, osteoarthritis (OA) mostly affects metacarpophalangeal and metatarsophalangeal (fetlock) joints. The current modalities used for diagnosis of equine limb disorders lack ability to detect early OA. Here, we propose a new alternative approach to assess experimental cartilage damage in fetlock joint using Acoustic Emissions (AE). Objective: To evaluate the potential of AE technique in diagnosing OA and see how AE signals changes with increasing severity of OA. Methods: An in vitro experimental study. Methods: A total of 16 distal limbs (8 forelimbs and 8 hindlimbs) from six Finn horses...
