Abstract
A knee orthosis is provided. In described embodiments, the knee orthosis is designed to follow a natural movement of a wearer's knee along an asymmetric helicoidal axis of rotation. In some embodiments, the knee orthosis has hinges with shells having displacing geometric centers which do not coincide. In some embodiments, the knee orthosis is made of femoral and tibial hinges manufactured as single integral pieces. In some embodiments, the orthosis is configured to realign the wearer's knee in a frontal plane. Corresponding methods for designing and manufacturing a custom knee orthosis are also provided.
Claims32
A knee orthosis comprising:
- a femoral section comprising a femoral cuff and a femoral hinge integrally formed as part of a single piece;
- and
- a tibial section comprising a tibial cuff and a tibial hinge, said tibial cuff and tibial hinge being integrally formed as part of a single piece,
- the femoral hinge and the tibial hinge being pivotally engaged to define an orthosis articulation allowing the femoral section and the tibial section to pivot relative to one another about a pivot axis, said pivot axis being configured to move in a sagittal plane, a frontal plane and a transverse plane, as the femoral and tibial sections are pivoted relative to one another about the articulation.
