Abstract

A brace for supporting a knee joint is disclosed which is specifically adapted for use in post-surgical applications. The brace is formed by an upper pair of struts and a lower pair of struts which are disposed on opposite sides of the knee joint and which include end portions which are pivotally connected by way of ratio-swing hinge members. A plurality of cuffs are provided which are used to interconnect the struts comprising the upper pair and the lower pair. Means are additionally provided to adjust the position of an upper strut and lower strut relative the cuffs.

Claims

1. A post-surgical knee brace comprising:

an upper pair of struts and a lower pair of struts, said upper pair and said lower pair being positionable in an inverted, relative orientation above and below the knee joint of a user with the end portions of said upper pair and said lower pair being disposed laterally on opposite sides of the knee joint;

a pair of hinge members disposed substantially adjacent the knee joint and connected to the end portions of the upper pair and lower pair to pivot the upper pair and lower pair about the knee joint;

at least one upper cuff interconnecting said upper pair of struts and disposed adjacent the rear of the user'"'"'s leg;

at least one lower cuff interconnecting said lower pair of struts and disposed adjacent the rear of the user'"'"'s leg;

a first slot disposed in said upper cuff for allowing a first lateral strut of said upper pair to be slidably positionable relative said upper cuff; and

a second slot disposed in said lower cuff for allowing a second lateral strut of said lower pair to be slidably positionable relative said lower cuff;

said first lateral strut and said second lateral strut being interconnected by one of said hinge members and being selectively positionable relative the knee joint via said first and second slots.

2. The knee brace of claim 1 further comprising;

at least one upper strap mounted to said upper cuff and extensible about the front of the user'"'"'s thigh; and

at least one lower strap mounted to said lower cuff and extensible about the front of the user'"'"'s calf.

3. The knee brace of claim 2 further comprising an upper slot disposed in said upper strap so as to be in general alignment with said first slot when said upper strap is mounted to said upper cuff, said upper strap further including indicia thereon adjacent said upper slot to selectively position the first lateral strut relative the upper cuff.

4. The knee brace of claim 3 further comprising a lower slot disposed in said lower strap so as to be in general alignment with said second slot when said lower strap is mounted to said lower cuff, said lower strap further including indicia thereon adjacent said lower slot to selectively position the second lateral strut relative the lower cuff.

5. The knee brace of claim 1 further comprising means formed on said pair of hinge members for regulating the relative pivotal movement of said upper pair of struts and said lower pair of struts.

6. The knee brace of claim 5 further comprising means formed on said pair of hinge members for limiting the extension of said upper pair of struts and said lower pair of struts.

7. The knee brace of claim 1 further comprising a first pad releasably attachable to said upper cuff and a second pad releasably attachable to said lower cuff, said first and second pads being adapted to provide a padded interface between said upper and lower cuffs and the user'"'"'s leg.

8. A post-surgical brace comprising:

an upper pair of struts and a lower pair of struts, said upper pair and said lower pair being positionable in an inverted, relative orientation above and below the knee joint of a user with the end portions of said upper pair and said lower pair being disposed laterally on opposite sides of the knee joint;

a pair of hinge members disposed substantially adjacent the knee joint and connected to the end portions of the upper pair and lower pair to pivot the upper pair and lower pair about the knee joint;

a first cuff and a second cuff interconnecting said upper pair of struts and disposed adjacent the rear of the user'"'"'s thigh;

a third cuff and fourth cuff interconnected said lower pair of struts and disposed adjacent the rear of the user'"'"'s calf;

a first slot disposed in said first cuff and a second cuff disposed in said second cuff, said first and second slots being adapted to allow a first lateral strut of said upper pair to be slidably positionable relative said first and second cuffs; and

a third slot disposed in said third cuffs and a fourth slot disposed in said fourth cuff, said third and fourth slots being adapted to allow a second lateral strut comprising said lower pair to be slidably positionable relative said third and fourth cuffs;

said first lateral strut and said second lateral strut being interconnected by one of said hinge members and being slidably positionable relative said first, second, third, and fourth cuffs via said first, second, third, and fourth slots.

9. The knee brace of claim 8 further comprising:

a first strap mounted to said first cuff and a second strap mounted to said second cuff, said first and second straps being extensible about the front of the user'"'"'s thigh; and

a third strap mounted to said third cuff and a fourth strap mounted to said fourth cuff, said third and fourth straps being extensible about the front of the user'"'"'s calf.

10. The knee brace of claim 9 further comprising a fifth slot disposed in said first strap and a sixth slot disposed in said second strap, said fifth and sixth slots being in general alignment with said first and second slots, respectively, when said first strap is mounted to said first cuff and said second strap is mounted to said second cuff, said first strap and said second strap further including indicia thereon adjacent said fifth and sixth slots to selectively position the first lateral strut relative the first and second cuffs.

11. The knee brace of claim 10 further comprising a seventh slot disposed in said third strap and an eighth slot disposed in said fourth strap, said seventh and eighth slots being in general alignment with said third and fourth slots, respectively, when said third strap is mounted to said third cuff and said fourth strap is mounted to said fourth cuff, said third and fourth straps further including indicia thereon adjacent said seventh and eighth slots to selectively position the second lateral strut relative the third and fourth cuffs.

12. A post-surgical knee brace comprising:

an upper pair of struts and a lower pair of struts, said upper pair and said lower pair being positionable in an inverted, relative orientation above and below the knee joint of a user with the end portions of said upper pair and said lower pair being disposed laterally on opposite sides of the knee joint;

a pair of hinge members disposed substantially adjacent the knee joint and connected to the end portions of the upper pair and lower pair to pivot the upper pair and lower pair about the knee joint;

at least one upper cuff interconnecting said upper pair of struts and disposed adjacent the rear of the user'"'"'s leg; and

at least one lower cuff interconnecting said lower pair of struts and disposed adjacent the rear of the user'"'"'s leg;

said upper and lower cuffs being slidably connected to said upper and lower pairs of struts and including indicia associated therewith so as to allow said upper pair and said lower pair to be selectively positionable laterally relative the knee joint.

13. The knee brace of claim 12 further comprising means formed on said pair of hinge members for regulating the relative pivotal movement of said upper pair of struts and said lower pair of struts.
