When an Orthosis Becomes Part of the Problem
This patient presented with a significant knee hyperextension deformity (genu recurvatum) that had developed while using a poorly designed orthosis.
An orthosis is not simply a brace that holds a limb in place. Its design, alignment, trimlines, joint positioning, and interaction with the patient's biomechanics can profoundly influence gait and joint loading.
In this case, an inappropriate orthotic design contributed to abnormal forces around the knee, progressively encouraging hyperextension rather than controlling it.
The lesson is simple:
A brace must be designed for the patient—not just for the diagnosis.
Every orthosis should be carefully assessed for: • Alignment
• Joint control
• Ground reaction forces
• Muscle strength
• Gait pattern
• Functional requirements
A poorly designed orthosis can create new problems. A well-designed orthosis can restore function, protect joints, and improve quality of life.
Precision in orthotic design is not an option. It is the treatment.
