Overview of the Current Osteoarthritis Treatment in Veterinary Medicine and Future Directions. Osteoarthritis (OA) is a chronic and progressive joint disease that can cause permanent loss of joint function. OA is highly prevalent in horses, dogs, and cats, affecting different joints and leading to reduced mobility and chronic pain. Different risk factors for animal OA have been identified, including trauma and breed. Inflammation is a hallmark of the disease, with various underlying mechanisms such as cyclooxygenase and metalloproteinase activation, nerve growth factor, cytokine, and prostaglandin upregulation, among others. Although disease complexity makes OA difficult to treat, eno...
Standing NanoNeedle Arthroscopy of the Distal Interphalangeal Joint for Removal of Osteochondral Fragments of Distal P2 and the Extensor Process in a Horse. In horses, standing arthroscopy offers a valuable alternative to general anesthesia for the reduction of anesthetic-associated risks, and provides improved visualization in joints where access is facilitated by weightbearing. These techniques are particularly advantageous for patients with increased anesthetic risk or financial limitations. To the authors' knowledge, the removal of osteochondral fragments from the distal interphalangeal joint in a standing, sedated horse using small-diameter arthroscopic equipment has not been previously reported.

Diagnostic Threshold Identification for Equine Laminitis Using Smoothed Receiver Operating Characteristic Analysis. Radiographic measurement parameters play a key role in diagnosing acute and subacute laminitis in horses, with diagnostic thresholds typically derived from empirical receiver operating characteristic (ROC) analysis. However, these methods often produce unstable results, particularly in small or noisy datasets. This study applies nonuniform rational B-spline (NURBS)-based ROC smoothing to radiographic data from laminitic and healthy horses to evaluate its effectiveness in refining diagnostic thresholds. Thresholds are determined using Youden's index based on NURBS-smoothed ROC curves and compar...
