A Seatbelt for your joints.
LigaSys is building Smart Ligament™ systems—reactive, garment-integrated wearable hardware that detects unsafe joint motion and mechanically engages in real time.
The Opportunity
3 million+ ankle sprains occur in the U.S. every year—making it one of the most common musculoskeletal injuries in the world.
Up to 80% of ankle sprain patients in high-risk sports suffer reinjury—creating a cycle that existing solutions don’t break.
$4 billion+ annual economic burden of ankle sprains in the U.S., including treatment, disability, and lost time.
Reimagining What Joint Protection Can Be
Ankle injuries happen in 40 to 80 milliseconds—faster than the nervous system can mount a protective response. Existing solutions—braces, tape, compression—work passively, constraining movement whether it’s dangerous or not.
LigaSys takes a different approach. Smart Ligament™ systems stay completely out of the athlete’s way during normal movement, then engage mechanically the instant dangerous motion is detected. Like a seatbelt—but for the joint.
