CLAIMS:

1. An adjustable knee brace for fitting a variety of leg sizes and adjustable to limit flexion or extension motion of a knee, the brace comprising:

a telescoping strut, comprising a strut member, a receiver configured to receive the strut member and telescopically positionable relative to the strut member, and a latch assembly mounted on the receiver, the latch assembly comprising a cam base having a cam surface adjacent a portion of the strut member received by the receiver and a pivot member pivotable mounted on the receiver for pivotal movement relative to the cam base, the pivot member having an engagement surface positioned to contact the cam surface of the cam base such that pivoting of the pivot member in one direction relative to the cam base selectively bears the cam base towards the strut member to apply a frictional force to lock the strut member and the receiver against relative telescoping movement, and pivoting the pivot member in an opposite direction removes the frictional force to unlock the strut member and the receiver and enable relative telescoping movement; and

a range of motion hinge operatively associated with the telescoping strut, the range of motion hinge comprising a hinge plate connected to the strut member and having a semi-circular peripheral edge defining a plurality of uniformly spaced apart keys, a range of motion stop movably positionable relative to the semi-circular peripheral edge, the range of motion stop including a movable latch having teeth, wherein the movable latch is movable away from the keys to an unlocked position in which the stop is movable relative to the keys, and the movable latch is movable toward and into engagement with the keys to a locked position in which the range of motion stop is not movable relative to the keys, wherein the range of motion stop defines a limit of rotational movement of the range of motion hinge to limit extension or flexion motion of the knee.

2. The knee brace of claim 1, wherein the cam surface comprises an alternating series of ramped and flat surfaces and the engagement surface comprises a negative contour of the cam surface.

3. The knee brace of claim 1, wherein the movable latch is movable by pivoting away from engagement with the keys and by pivoting into engagement with the keys.

4. The knee brace of claim 3, wherein the hinge plate is movable within a first plane and the latch is movable within a second plane perpendicular to the first plane.

5. A telescoping strut for an adjustable knee brace, comprising:

a strut member;

a receiver configured to receive the strut member and telescopically positionable relative to the strut member; and

a latch assembly mounted on the receiver, the latch assembly comprising a cam base having a cam surface adjacent a portion of the strut member received by the receiver and a pivot member pivotable mounted on the receiver for pivotal movement relative to the cam base, the pivot member having an engagement surface positioned to contact the cam surface of the cam base such that pivoting of the pivot member in one direction relative to the cam base selectively bears the cam base towards the strut member to apply a frictional force to lock the strut member and the receiver against relative telescoping movement, and pivoting the pivot member in an opposite direction removes the frictional force to unlock the strut member and the receiver and enable relative telescoping movement.

6. The telescoping strut of claim 5, wherein the cam surface comprises an alternating series of ramped and flat surfaces and the engagement surface comprises a negative contour of the cam surface.

7. The telescoping strut of claim 5, further comprising a pad mount connected to the strut member opposite the latch assembly with a wedge shaped spacer located

between the pad mount and the strut member, wherein the wedge shaped spacer may be provided in different slopes and thickness to enable a more custom fit to a leg of a patient wearing the brace.

8. An adjustable range of motion hinge for a knee brace limit flexion or extension motion of a knee, the hinge comprising:

a hinge plate having a semi-circular peripheral edge defining a plurality of uniformly spaced apart keys; and

a range of motion stop movably positionable relative to the semi-circular peripheral edge of the hinge plate, the range of motion stop including a movable latch having teeth, wherein the movable latch is movable away from the keys to an unlocked position in which the stop is movable relative to the keys, and the movable latch is movable toward and into engagement with the keys to a locked position in which the range of motion stop is not movable relative to the keys, wherein the range of motion stop defines a limit of rotational movement of the range of motion hinge to limit extension or flexion motion of the knee.

9. The hinge of claim 8, wherein the movable latch is movable by pivoting away from engagement with the keys and by pivoting into engagement with the keys.

10. The hinge of claim 9, wherein the hinge plate is movable within a first plane and the movable latch is movable within a second plane perpendicular to the first plane.

11. An adjustable knee brace for fitting a variety of leg sizes and adjustable to limit flexion or extension motion of a knee, the brace comprising:

a pair of telescoping struts, each strut comprising a strut member, a receiver configured to receive the strut member and telescopically positionable relative to the strut member, and a latch assembly mounted on the receiver, the latch assembly comprising

a cam base having a cam surface adjacent a portion of the strut member received by the receiver, and

a pivot member pivotable mounted on the receiver for pivotal movement relative to the cam base, the pivot member having an engagement surface positioned to contact the cam surface of the cam base such that pivoting of the pivot member in one direction relative to the cam base selectively bears the cam base towards the strut member to apply a frictional force to lock the strut member and the receiver against relative telescoping movement, and pivoting the pivot member in an opposite direction removes the frictional force to unlock the strut member and the receiver and enable relative telescoping movement; and

a range of motion hinge operatively associated with both of the telescoping struts, the range of motion hinge comprising:

a pair of mating hinge plates connected to each of the strut members, each hinge plate having a semi-circular peripheral edge defining a plurality of uniformly spaced apart keys, the hinge plates being facing and aligned so that the peripheral edges are aligned and the keys of each hinge plate are aligned to define a first key set and a second key set,

a flexion range of motion stop movably positionable relative to a first portion of the aligned semi-circular peripheral edges of the hinges, the flexion range of motion stop including a movable latch having teeth, wherein the movable latch is movable away from the first key set to an unlocked position in which the flexion range of motion stop is movable relative to the first key set, and the movable latch is movable toward and into engagement with the first key set to a locked position in which the flexion range of motion stop is not movable relative to the first key set, and

an extension range of motion stop movably positionable relative to a second portion of the aligned semi-circular peripheral edges of the hinges, the extension range of motion stop including a movable latch having teeth, wherein the movable latch is movable away from the second key set to an unlocked position in which the extension range of motion stop is movable relative to the second key set, and the movable latch is movable toward and into engagement with the second key set to a locked position in which the extension range of motion stop is not movable relative to the second key set,

wherein the flexion range of motion stop defines a limit of rotational movement of the range of motion hinge to limit flexion motion of the knee and the extension range of motion stop defines a limit of rotational movement of the range of motion hinge to limit extension motion of the knee.

12. The knee brace of claim 11, further comprising a sliding lock lever slidingly mounted to the range of motion hinge and slidingly engageable with one of the struts to lock the hinge at a desired orientation.

13. The knee brace of claim 12, wherein the strut with which the lock lever is engageable includes peripheral teeth engaged by the lock lever.
