Abstract
An orthopedic device has a rigid or semi-rigid frame element defining opposed first and second sides, and is adapted to extend about at least a portion of a limb. The device includes straps formed from a variety of segments having stretchable and substantially inelastic segments. The straps adjustably secure to the frame element, and stretch relative thereto. The device also includes a central strap pad arranged to connect two straps together such that a first strap of the two straps is movable relative to a second strap, and the first and second straps are maintained diagonal relative to one another.
Claims20
A knee brace, comprising:
- a first frame element;
- a second frame element;
- a hinge assembly connecting to the first and second frame elements;
- a force strap assembly extending helically between the first and second frame elements, a first end of the force strap assembly connecting to the first frame element, and a second end of the force strap assembly connecting to the second frame element;
- a linear ratchet assembly connecting to the first end of the force strap assembly and to the first frame element, the linear ratchet assembly having a ladder strap defining at least two teeth and a latch supported by a base forming a clearance with the latch through which the ladder strap extends, the latch being arranged to selectively engage at least one of the at least two teeth of the ladder strap and to selectively release from the at least one of the at least two teeth of the ladder strap in a linear movement, wherein regulation of the linear ratchet assembly permits drawing the first end of the force strap assembly toward and away from the first frame element;
- and
- a buckle assembly connecting the second end of the force strap to the second frame element, the buckle assembly releasably secured to the second frame element;
- a stability strap extending from the buckle assembly on a first side of the second frame element and extending to pivotally connect to a second side of the second frame element.

- a linear ratchet assembly connecting to the first end of the force strap assembly and to the first frame element, the linear ratchet assembly having a ladder strap defining at least two teeth and a latch supported by a base forming a clearance with the latch through which the ladder strap extends, the latch being arranged to selectively engage at least one of the at least two teeth of the ladder strap and to selectively release from the at least one of the at least two teeth in a linear movement, wherein regulation of the linear ratchet assembly permits drawing the first end of the force strap assembly toward and away from the first frame element;
- and
- a dosage meter located proximate the at least two teeth of the ladder strap for indicating a relative position of the first end of the force strap assembly to the first frame element, the dosage meter including a plurality of numbers generally corresponding to the at least two teeth of the ladder strap.

- a linear ratchet assembly connecting to the first end of the force strap assembly and to the first frame element, the linear ratchet assembly having a ladder strap defining at least two teeth and a latch supported by a base forming a clearance with the latch through which the ladder strap extends, the latch being arranged to selectively engage at least one of the at least two teeth of the ladder strap and to selectively release from the at least one of the at least two teeth in a linear movement, wherein regulation of the linear ratchet assembly permits drawing the first end of the force strap assembly toward and away from the first frame element;
- and
- first and second liners arranged to correspond in shape to the first and second frame elements, respectively, the first liner including a first surface formed from a material selected from the group consisting of doeskin, microfiber, and suede, the second liner has a first surface arranged for greater resistance to movement than the first liner when pressed against skin of a user of the knee brace, each of the first and second liners defining a compressible core along which the first surfaces of the first and second liners secure, the first and second liners having a second surface opposite the first surfaces secured to the first and second liners, respectively.
