Degenerative Gelenkerkrankung
Also known as: Equine Arthrose
Die degenerative Gelenkerkrankung (Arthrose) ist der fortschreitende Abbau des Gelenkknorpels und des umgebenden Knochens bei Pferden und Eseln. Sie ist eine der Hauptursachen für chronische Lahmheit, besonders bei sportlich genutzten und alternden Tieren. Betroffene Gelenke werden mit der Zeit steif, schmerzhaft und verlieren an Beweglichkeit.

Overview
Degenerative joint disease, or osteoarthritis, is progressive breakdown of articular cartilage with secondary changes in bone and the joint capsule. It is one of the most common causes of chronic lameness and reduced performance in horses and a frequent problem in aging donkeys.
Causes
Repetitive concussion and stress, joint instability, previous injury, intra-articular fractures, infection, conformational faults, and developmental disease all contribute. Wear accumulates over years, especially in hardworking and older animals.
Signs
Signs include lameness that often worsens with work, joint stiffness and reduced flexibility, joint swelling, heat, and a shortened stride. Donkeys may mask discomfort and simply move less or lose condition.
Diagnosis
Lameness examination with flexion tests, diagnostic joint blocks, and radiographs showing narrowed joint space and bony spurs confirm the diagnosis; ultrasound and MRI assess soft tissues.
Treatment & Management
Management includes controlled exercise, weight control, anti-inflammatory drugs, joint injections, corrective farriery, and joint-supportive medications. The goal is to relieve pain and slow progression.
Prevention
Appropriate workloads, good footing, balanced hoof care, weight control, and prompt treatment of joint injuries help delay onset.
