LinkedInLimbRise lets people recovering from knee-and-below injuries move, work, and live with both hands free.
Every year, 20 million North Americans injure their leg, and most end up on crutches that tie up both hands, cause secondary injuries, and slow them down. Nearly one third give up on them entirely.
Existing hands-free crutches only support foot and ankle injuries. LimbRise is the first designed for knee injuries.
| Injury | LimbRise | Other hands-free crutches |
|---|---|---|
| Knee | ✓ | ✕ |
| Foot & ankle | ✓ | ✓ |
Straps securely to the lower leg and thigh. Adjustable across a target fit range.
Redirects the load into your sitting bone, away from the injured limb.
Move with both hands free. Stabilize your core like a yoga ball.
Maintain your daily life, without the setbacks that slow down recovery.
Designed with 5 surgeons, 6 physiotherapists, and 4 biomechanists.
