Discomfort may arise from the suspensory ligaments themselves, other soft tissues like muscle and tendon that are trying to compensate, the changing conformation of the limb (ie straightening of the hock angle), and even arthritis due to abnormal stress on joints. The suspensory ligament is a thick, strong, tendon-like structure running down the back of the leg from the knee or hock to the fetlock, providing critical support to this joint. Resulting in ligament breakdown, flexor tendon injury, and osteoarthritis in the fetlock, hock, and stifle joints leading to debilitating lameness. This means the horse may be passing the disease on unknowingly. Equine degenerative suspensory ligament desmitis (DSLD) in Peruvian Paso horses typically presents at 7-15 years and is characterized by lameness, focal disorganization of collagen fibrils, and chondroid deposition in the body of the ligament.

There is no cure for DSLD. Treatment focuses on keeping the horse comfortable with pain relief and corrective shoeing. Ultrasonographic evaluation of the suspensory ligaments usually reveals increased circumference of the branches. These horses also typically do best when kept on as much turnout as possible. However, this must be done correctly and under close observation to prevent secondary issues such as damage to other tendons and ligaments, pressure sores on the skin, or further laxity in the suspensory ligaments from relying on bandages 24/7.
