Case 3: Thoroughbred Racehorse with Left Hind Proximal Suspensory Ligament Tear

OVERVIEW

The horse presented with

• A Thoroughbred racehorse that went lame after a race.
• Diagnostic work-up identifying a proximal suspensory ligament (PSL) tear in the left hind, graded as a strong Grade 3 lameness.

Gait analysis at presentation showed pronounced push-off asymmetry with mild impact asymmetry in the left hind, and very mild push-off asymmetry in the left front.

TREATMENT APPROACH

The plan, in order

• equicenta® CTM injection at the LH proximal suspensory ligament tear.

OUTCOME

Day 90 — Cleared to Gallop

At the 90-day recheck, the horse was Grade 0 and sound, with gait analysis showing values back near baseline across all measures. The horse had progressed to starting gallop work.

CLINICAL TAKEAWAY

A proximal suspensory ligament tear in a racing Thoroughbred is a high-stakes injury for return to performance. This case shows a strong Grade 3 lameness returning to Grade 0 and cleared for galloping within 90 days of equicenta® CTM treatment.¹

Individual case; results may not be representative. Multiple concurrent treatments may have been used. This case is not evidence of effectiveness.

FINAL THOUGHT

Horse First, Sport Second.

At Equine Performance Labs, cases like this reinforce our core belief: meaningful recovery isn’t just about returning to work — it’s about restoring comfort, function, and longevity in every stride.
