Systems, devices, and methods for adjusting rotational limits of an orthopedic brace hinge are provided. A hinge stop assembly limits rotational travel of first and second frame members of the hinge. An indexing key of the hinge stop assembly is actuatable in a direction parallel to the axis of rotation of the hinge to lock and unlock the position of the hinge stop assembly relative to the hinge. Actuation of the hinge stop assembly unlocks the indexing key and allows movement of the hinge stop assembly to set a desired limit on the flexion or extension of the brace hinge. Release of the hinge stop assembly locks the indexing key and locks the hinge stop assembly in place.

1. A hinge assembly for an orthopedic brace, comprising: a hinge cover having a center rotation axis;first and second frame members pivotably connected to the hinge cover; andat least one hinge stop assembly operable with the hinge for limiting rotational travel of the second frame member, the at least one hinge stop assembly having an indexing key that is biased toward a first position and actuatable parallel to the center rotation axis of the hinge to a second position, wherein: a rotational limit of the second frame member is locked when the indexing key is in the first position, andthe hinge stop assembly is movable around the center rotation axis when the indexing key is in the second position. 2. The hinge assembly claim 1, further comprising a first hinge plate positioned between the hinge cover and the first and second frame members. 3. The hinge assembly of claim 2, wherein the first and second frame members are positioned between the first hinge plate and a second hinge plate. 4. The hinge assembly of claim 3, wherein the first and second hinge plates have gear teeth configured to engage the at least one hinge stop assembly. 5. The hinge assembly of claim 4, wherein the indexing key engages the gear teeth when the indexing key is in the first position. 6. The hinge assembly of claim 4, wherein the at least one hinge stop assembly includes a hinge stop face for making contact with the second frame member, the hinge stop face extending between the first and second hinge plates. 7. The hinge assembly of claim 1, wherein the at least one hinge stop assembly includes an upper housing having a pocket for receiving the button. 8. The hinge assembly of claim 1, comprising a locking mechanism having a locking pin configured to engage gear teeth disposed on first and second hinge plates. 9. The hinge assembly of claim 1, comprising a button that is actuatable in a direction perpendicular to the center rotation axis of the hinge. 10. The hinge assembly of claim 9, comprising a ramp on the indexing key, the ramp facing radially and angularly away from the center rotational axis of the hinge. 11. The hinge assembly of claim 10, wherein the indexing key includes a plurality of arms that fit within corresponding notches disposed within the hinge to form a hinge stop location to limit the angular rotational travel of the second frame member. 12. The hinge assembly of claim 11, further comprising a button wherein the button and indexing key both fit within a receptacle disposed between first and second hinge plates. 13. The hinge assembly of claim 10, wherein the button includes a platform that interfaces with the ramp and that, upon actuation, drives the ramp in a direction that is parallel to the central rotational axis of the hinge assembly. 14. The hinge assembly of claim 9, wherein the indexing key and actuator, when assembled, are disposed between first and second hinge plates, and are actuatable in a direction perpendicular to the central rotational axis of the hinge assembly. 15. A method of adjusting rotation of an orthopedic brace that includes first and second frame members, a hinge having a center rotation axis, and a hinge stop assembly, said method comprising: actuating the hinge stop assembly to cause an indexing key to move in a direction parallel to the center rotation axis of the hinge;positioning the hinge stop assembly around the hinge; andreleasing the hinge stop assembly, wherein said releasing causes the indexing key to move in a direction parallel to the center rotation axis of the hinge and lock the hinge stop assembly in position relative to the hinge. 16. The method of claim 15, wherein said actuating comprises applying a force to an actuator button connected to the hinge stop assembly. 17. The method of claim 16, wherein said actuating further comprises applying a force to the actuator button in a direction perpendicular to the center rotation axis of the hinge. 18. The method of claim 16, wherein said actuating further comprises applying a force to the actuator button in a direction parallel to the center rotation axis of the hinge. 19. The method of claim 15, wherein the hinge comprises a hinge plate, and said positioning comprises moving the hinge stop assembly about a perimeter of the hinge plate. 20. The hinge assembly of claim 5, wherein the indexing key disengages the gear teeth when the indexing key is actuated to the second position.
