Plain-English summary
This study looked at two unusual floating particles found in the knee joint (stifle) of an adult male draught horse. These particles, which looked similar to rice bodies seen in humans with rheumatoid arthritis, were actually made up of degenerated tissue from the joint lining. The researchers believe that these particles formed due to a lack of blood flow in the area. This finding adds to our understanding of different types of joint issues in horses.
Abstract
In the human and equine species, different kinds of free floating intra-articular particles are related to certain disorders. Osteochondral fragments formed during osteochondrosis dissecans are the most common finding in the equine species, whereas in humans rice bodies due to rheumatoid arthritis are more frequent. Herein we report a third type of floating body inside the stifle of an adult draught horse stallion, in macroscopic appearance similar to articular rice bodies known in humans. As revealed by histologic examination, the two particles consist of polypoid degenerated structures derived from synovial villi. Their formation was probably induced by ischemia.
