Non-Invasive System for
Supporting Pediatric
Orthopedic Alignment.

Over 2.8 million children in the US alone have lower limb malalignment that will not self-correct. Until now, their only proven option was surgery. GV Correct changes that.

The Problem

A large, underserved population with no good non-surgical option.

Lower limb malalignment is common in children. In many cases, this issue resolves naturally over time. But a significant population presents with persistent deformity — causing pain, gait disturbance, and long-term joint damage — and today faces a binary choice: wait indefinitely, or undergo invasive surgery.

There is no proven non-invasive intervention that bridges the gap between observation and surgery. That is the gap GV Correct is built to fill.

How It Works

A smart orthopedic system. Not a brace.

The GV Correct garment applies precisely calibrated mechanotherapeutic pressure to guide limb alignment during normal daily activity. With a recommended wear time of around 8 hours a day, it delivers measurable results — while an embedded wireless sensor and the SmartAlign™ app give parents and clinicians real-time compliance data.

Mechanotherapeutic garment
Calibrated elastic straps apply medial pressure during movement. No restriction of daily activity — designed to be worn to school, during play, and everyday life.
Wireless pressure monitoring
A 9g sensor transmits pressure readings to the cloud continuously. Both parents and clinicians track adherence and treatment progress in real time.
SmartAlign™ app
Parents monitor wear time and pressure range. Clinicians access an AI-ready dashboard. Alerts when readings drift outside the recommended pressure range.

Who It's For

Built for every child who needs it — mild to moderate cases.

GV Correct is designed for children aged 7–12 presenting with lower limb malalignment across the full mild-to-moderate spectrum. The earlier therapy begins during the growth years, the better the outcome. The next generation of GV Correct is being developed to extend to more severe presentations as well.

1
Child aged 7–12 with lower limb malalignment
The active growth phase makes this the most effective window for non-invasive therapy. GV Correct works with the body's natural development.
2
Mild to moderate severity
GV Correct addresses the broad population who would benefit from early intervention — before the condition progresses or surgical options arise.
3
Used with or without a clinical referral
GV Correct fits naturally into a clinical workflow — and is designed to be accessible enough for families to use independently. FDA Class I Exempt, no prescription required.
4
A non-invasive first-line option
For the first time, families and clinicians have an evidence-based, measurable, non-surgical tool — before watchful waiting becomes a longer-term problem.

FAQ

Common questions.

Everything parents and families need to know before getting started.

Does my child need a prescription?
No. GV Correct is classified as FDA Class I Exempt, meaning no prescription is required. That said, we always recommend involving your child's pediatrician or orthopedist in the decision.
What ages does it work for?
GV Correct is designed for children aged 7–12 — the window during which the body's growth plates are still open and most responsive to non-invasive alignment support.
Is it painful or uncomfortable?
No. The pressure applied by GV Correct is carefully calibrated to guide alignment without causing pain or discomfort. Importantly, the pressure is adjustable — it can be gradually increased over time as the child adapts, or raised if the child tolerates and benefits from a higher level. This allows treatment to be personalised and progressed at the child's own pace. Pressure levels are monitored in real time through the SmartAlign™ app.
How is this different from orthotics or bracing?
Traditional bracing has no published clinical evidence for genu valgum or varum. GV Correct is the only peer-reviewed, sensor-monitored, data-driven garment in this category.
What if my child won't wear it consistently?
The SmartAlign™ app tracks wear time and pressure compliance daily — giving parents and clinicians visibility into adherence. The garment is designed with comfort, discretion, and kid-friendly wear in mind, which itself supports higher compliance. Children are more likely to keep wearing something that feels natural and fits into their daily routine.
Is this covered by insurance?
Insurance coverage is not yet available. GV Correct is currently a cash-pay product. A reimbursement pathway via CPT coding is in development for future clinical distribution.
