What factors influence prognosis for a horse with suspensory ligament injury?

• A. Lesion severity and location, chronicity, response to therapy, age, hoof balance, rehabilitation adherence, and workload management.
• B. Diet alone dictates prognosis.
• C. Only lesion size matters.
• D. Climate is the primary prognostic factor.

Answer: (A)

Prognosis for suspensory ligament injuries depends on several interacting factors that reflect both tissue healing and how the horse is managed during rehab. The severity and exact location of the lesion determine how much tissue is damaged and which parts of the suspensory apparatus are involved, so a small, distal tear can heal differently from a larger core lesion or a proximal injury. Chronicity matters because acute injuries often remodel better, while long-standing damage may have fibrotic changes that limit recovery. How the horse responds to therapy is also telling—improvement in lameness and ultrasound signs of healing suggest a more favorable course and help tailor expectations. Age can slow healing and remodeling, while hoof balance influences how loads are distributed across the ligament; improper balance can place extra stress and hinder recovery. Rehabilitation adherence and careful workload management are crucial: a structured, progressive rehab plan and gradual, appropriate loading reduce re-injury risk and support a better outcome.
