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. |
