Topic:Cartilage
Cartilage in horses is a specialized connective tissue found in joints, providing a smooth, lubricated surface for articulation and facilitating the transmission of loads with low friction. It is composed of chondrocytes embedded within an extracellular matrix rich in collagen fibers, proteoglycans, and water. Cartilage does not contain blood vessels or nerves, relying on diffusion for nutrient delivery and waste removal. This avascularity contributes to its limited capacity for repair and regeneration. Research on equine cartilage focuses on understanding its structure, function, and the biological processes involved in cartilage development, maintenance, and degeneration. Studies also explore the impact of various conditions, such as osteoarthritis, on cartilage integrity and investigate potential therapeutic approaches for cartilage repair and preservation. This page gathers peer-reviewed research and scholarly articles that delve into the biology, pathology, and treatment of cartilage-related conditions in horses.
Scanning electron microscopy of equine synovial membrane. The scanning electron microscopy of synovial membrane from the radiocarpal and intercarpal joints near the lateral and medial borders of the tendon of the extensor carpi radialis muscle was studied in 5 ponies. Three different morphologic types of synovial membrane were observed. Type 1 synovial membrane was folded and had a surface mat of fibers separated by 1- to 5-micron-diameter holes. The 2nd and 3rd types of synovial membrane were both villous. The surface of type 2 synovial membrane was fibrillar but the surface of type 3 synovial membrane was cellular. The type of synovial membrane pre...
Equine Allogeneic Chondrogenic Induced Mesenchymal Stem Cells Are an Effective Treatment for Degenerative Joint Disease in Horses. Degenerative joint disease is one of the main causes of equine early retirement from pleasure riding or a performance career. The disease is initially triggered by an abnormal loading of normal cartilage or a normal loading of abnormal cartilage. This primary insult is accompanied with joint inflammation, which leads to further progressive degeneration of the articular cartilage and changes in the surrounding tissues. Therefore, in search for an effective treatment, 75 adult horses with early signs of degenerative fetlock joint disease were enrolled in a randomized, multicenter, double-blinded...
The genetics of equine osteochondrosis. Osteochondrosis (OC) develops in growing horses due to disturbed differentiation and maturation of cartilage, particularly at the predilection sites of the fetlock, hock and stifle joints. Horses with osteochondrotic lesions are at a high risk of developing orthopaedic problems later in life. This article briefly reviews the published heritability estimates for OC and offers perspectives for selection in the horse industry. Heritabilities for OC in Warmblood and Standardbred horses have been estimated at 0.1-0.4 in animal threshold models. Whole genome scans using microsatellites have identifi...
Detection of experimental cartilage damage with acoustic emissions technique: An in vitro equine study. 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...
