Bridging the Gap in Canine Orthotics: Kirsten Häusler’s Research on Stifle Bracing
For years, the veterinary community has maintained a cautious—and sometimes skeptical—stance regarding orthotics for managing cranial cruciate ligament (CCL) ruptures. While surgery remains the traditional standard of care, many patients are not ideal candidates due to advanced age, comorbidities, or financial constraints. Custom stifle bracing offers a promising alternative, yet clinical uptake has been hampered by a lingering question: Does wearing a brace cause compensatory mechanical issues or restrict movement elsewhere?
At the 11th International Association of Veterinary Rehabilitation and Physical Therapy (IAVRPT) Symposium, Kirsten Häusler presented groundbreaking clinical research that addresses this exact concern head-on. Find full proceedings here
The Findings: Preservation of Natural Mechanics
Häusler’s study evaluated sound, adult Border Collies walking and trotting on an instrumented treadmill under three distinct conditions: baseline (no brace), while wearing a patient-specific custom stifle brace on the left hindlimb, and immediately post-removal.
Using high-precision gait analysis, the study monitored spatial and temporal gait parameters—including symmetry indices, step length, and peak loading across all four limbs.
Key insights from the presentation include:
-
No Step Length or Symmetry Deficits: The patient-specific brace provided structural joint support without restricting natural step length or compromising gait symmetry.
-
Zero Adverse Compensatory Load: Crucially, the orthotic produced no negative compensatory shift to the front limbs or contralateral hindlimb.
-
Improved Hindlimb Loading: During trotting, wearing the brace resulted in improved, balanced weight bearing across the hindlimbs.
What This Means for the Veterinary Perspective
Häusler’s study represents a critical pivot point in how veterinary professionals evaluate non-surgical orthotic options. Historically, critics feared that rigid external bracing might artificially lock down joint mechanics, forcing the dog to alter its stride and overcompensate with healthy limbs.
By demonstrating that custom-designed stifle orthotics preserve natural temporospatial gait parameters without inducing mechanical stress elsewhere, Häusler’s work validates orthotics as a safe, biomechanically sound intervention. It lays key objective groundwork showing that a brace can offer stability without forcing detrimental trade-offs.
As objective gait analysis continues to replace anecdotal assumptions, research like Häusler’s equips veterinarians and rehabilitation practitioners with the evidence needed to confidently recommend stifle bracing as a primary or supportive therapy for CCL injury management.
