Definitions
- This invention relates to a corrective and protective knee brace, and more particularly to a brace which may be worn for long periods without interfering with normal circulation. It is an improvement on Patent No. 2,467,- 907, issued April 19, 1949, to the same inventor.
- Corrective and protective braces for the joints of the human body are generally designed to supplement or substitute for parts tof the point, or parts of the extremities associated with the joint.
- Such braces normally limit the joint to a range of movement permitting normal function of the joint without undue strain.
- the parts :of a joint may be naturally weak or may become weakened due to injuries or diseases such as old fractures, torn ligaments, arthritis or polio.
- the parts may also be weakened by diseases or injuries affecting the spinal cord or peripheral nerve and in which the muscles which control the function of the joint have become involved.
- Braces for preventing injury to the joint in athletics, or for pre-operative or post-operative protection -for a weakened joint, or a joint injured through accident or disease, must provide support for the joint, and also should provide as near normal freedom of movement as possible.
- Such braces and in particular knee braces, usually employ straps or other means for encircling the knee in order to apply pressure on the knee proper. It 1s obvious that, ordinarily, whatever pressure is applied to the knee joint itself, equal pressure must be applied by straps elsewhere to the extremity involved, in this case, the leg. Straps, or other leg-encircling means, tend to interfere in varying degree with arterial and venous blood circulation as well as with the lymph supply to the structure of the limb involved. y
- ⁇ It is, accordingly, the principal object of the present invention to provide a corrective and protective brace for a joint which will allow for a normal range of motion of the joint and, at the same time, will take the place of or supplement the function of one or more of the parts of the joint which have become weakened or injured as the result of accident, disease or natural causes.
- a further important object of the invention is to provide a corrective and protective knee brace in which maximum support can be applied to the knee joint with a minimum amount of interference with the normal blood supply or circulation of the limb associated therewith.
- a more particular object of the invention is to provide a protective and corrective knee brace that is adapted for use in the prevention of injuries, in the treatment of injuries, in casesin which the knee requires pre-operative or post-operative support, or in cases where the knee has been weakened as the result of injury or disease.
- Afurther object is to provide a supporting knee brace which, when adjusted,.holds lateral and rotative motion of the knee joint within normal limits, while allowing substantially a normal .range of motion inthe joint.
- a knee brace having means for encircling the leg without the application of concurrent pressures on the leg that interfere with normal circulation, and which applies corrective and supporting pres- -sure to the lateral and medial sides of the knee joint with- .out pressure on the popiteal space posterior to the knee that would interference with the blood supply t-o the leg. Still other objects ⁇ are to provide a knee brace which may be easily put on and taken olf and which may be easily adjusted initially to apply the proper pressure to the joint.

- the pads 64 and 65 are preferably somewhat larger than the above described pads 11 and 12, and the metal or stiif leather plates 66 and 67 to which they are stitched are accordingly larger. Plates 66, 67 are preferably dished or' cupped, as shown, and may both be oval in shape.
- straps 62 and 63 are stitched to the top and bottom, respectively, of the plates 66 and 67 and are 468, which may be a sleeve such as the above described elastic sleeve 1 or simply a half sleeve, as shown, extending around the rear of the knee for holding the pads in position while fastening the brace.
- members 60 and 61 are secured .respectively to the plates 66 and 67 by rivets 69, and the members curve around behind the knee, spaced therefrom like the rear portion of the above described members 20 and 21. Means are provided for drawing together the rear ends of members 60 and 6l, to put pressure on the pads 64 and 65, such as the toggle latch 67 previously described.
- Members 60 and 61 and the latch 27 may have a protective covering for sport use.
- the operation of the brace of FIGURES 24-27 is much the same as for the other above described embodiments.
- the brace is pulled on over the foot and pulled up to the knee with the pads 64 and 65 on either side of the joint.
- Latch 27 is.then adjusted and closed to draw the pads together. Since the straps 62 and 63 contact the bony portions of the front of the leg above and below the knee, they prevent the pads from being drawn to the rear, and consequently the pads put the desired pressure on either side of the knee when latch 27 is closed.
- the straps 62 and 63 are held taut against the front of the leg by the elastic half-sleeve 68 until latch 27 is closed. Thereafter, the pressure on the pads maintains the brace in place, and the arm members 66 and 61 are held spaced from the back of the knee. The popiteal space posterior to the knee is therefore free from constriction, and circulation to the limb below the knee is without interference, while the knee joint is supported by the pads 66 and 67 as hereinabove described.
- the main vessels which supply and return blood to and from the lower portions of the leg are located in the popiteal space posterior to the knee and the brace does not .exert pressure on or otherwise interfere with this area.
- the pressure which can be supplied against the joint may be easily adjusted initially by the toggle adjustment afforded by the parts 31, 40, or members 50, 56, and the pressure can be quickly applied by the toggle latch 27 or 27 Consequently, after the initial adjustment, the knee brace lof the present invention may be quickly and easily put on and taken oif by the wearer.
- the brace may be worn by orthopedic patients who ordinarily cannot freeiy move about because of the pain incident to the weight born by an injured or damaged knee. With the brace such patients can move about with safety while healing is taking place. In industry, time ordinarily lost by disabled workers with pre-operative and post-operative knees may be safely cut to the minimum by using the brace, and in some cases the necessity for operative attention may be eliminated by wearing the brace While natural healing takes place.

'Y n l Y The operation ofthe brace' offYFIGURES 8'10"isfthe'V 1 same' as 'aboved'escribed for the embodiment of FIG` URES 1 3. The hinged joint between the upper portions 23a and 24a of members '20' and 21 being above and axially aligned with the hinged joint between the lower portions 23 and 24', the encircling members 20 and 21 -may be expanded and contracted by operation of the toggle latch 27 for applying and removing the brace. The initial adjustment of the brace may be accomplished by moving the slide 56 along arm 21' away from anchor plate 50, moving the plate toward one end or the other of the recess 52 and returning slide 56 into engagement with plate 50.
In FIGURES 21 and 22 is shown a modified form of fastening device for securing the flap 45 of the protective covering of the knee encircling pressure members over the latching device. The flap 45 is provided with a tab 46' and the adjacent end of the covering 44 is provided with a pocket member 59 stitched to covering 44. The free end of the flap 45 is secured in place by slipping the tab 46 into the pocket formed by the member 59 as shown in FIGURES 21 and 22.
In FIGURES 24-27 another modified form of knee brace is shown in which the knee encircling structure comprises the rigid metal arm members 6) and 61 behind the knee, being joined together by a toggle latch 27, and substantially non-elastic straps 62 and 63, or other nonstretchable but flexible members, connecting the pads 64 and 65 infront of theknee'.
'The pads 64 and 65 are preferably somewhat larger than the above described pads 11 and 12, and the metal or stiif leather plates 66 and 67 to which they are stitched are accordingly larger. Plates 66, 67 are preferably dished or' cupped, as shown, and may both be oval in shape.
The ends of straps 62 and 63 are stitched to the top and bottom, respectively, of the plates 66 and 67 and are 468, which may be a sleeve such as the above described elastic sleeve 1 or simply a half sleeve, as shown, extending around the rear of the knee for holding the pads in position while fastening the brace.
The forward ends of members 60 and 61 are secured .respectively to the plates 66 and 67 by rivets 69, and the members curve around behind the knee, spaced therefrom like the rear portion of the above described members 20 and 21. Means are provided for drawing together the rear ends of members 60 and 6l, to put pressure on the pads 64 and 65, such as the toggle latch 67 previously described.
The operation of the brace of FIGURES 24-27 is much the same as for the other above described embodiments. The brace is pulled on over the foot and pulled up to the knee with the pads 64 and 65 on either side of the joint. Latch 27 is.then adjusted and closed to draw the pads together. Since the straps 62 and 63 contact the bony portions of the front of the leg above and below the knee, they prevent the pads from being drawn to the rear, and consequently the pads put the desired pressure on either side of the knee when latch 27 is closed.
The straps 62 and 63 are held taut against the front of the leg by the elastic half-sleeve 68 until latch 27 is closed. Thereafter, the pressure on the pads maintains the brace in place, and the arm members 66 and 61 are held spaced from the back of the knee. The popiteal space posterior to the knee is therefore free from constriction, and circulation to the limb below the knee is without interference, while the knee joint is supported by the pads 66 and 67 as hereinabove described.
It will now be apparent that there has been provided a brace which firmly prevents lateral motion and rotative motion of the knee joint beyond the normal limits by reason of the compressive action of the pressure pads. The pads in turn are held in place by the compressive action provided by the rigid leg-encircling members, and also by reason of the attachment of the pads to the elastic sleeve 1 or half sleeve 68 and straps 62 and 63. Normal flexion and extension of the knee joint Within its normal range is therefore not restricted.
The main vessels which supply and return blood to and from the lower portions of the leg are located in the popiteal space posterior to the knee and the brace does not .exert pressure on or otherwise interfere with this area. There is very little, and purely localized, blood supply provided to the knee on its lateral and medial sides, and, consequently, interference with the blood and lymph supply to the knee and lower extremity is minimal.
The pressure which can be supplied against the joint may be easily adjusted initially by the toggle adjustment afforded by the parts 31, 40, or members 50, 56, and the pressure can be quickly applied by the toggle latch 27 or 27 Consequently, after the initial adjustment, the knee brace lof the present invention may be quickly and easily put on and taken oif by the wearer.
The brace may be worn by orthopedic patients who ordinarily cannot freeiy move about because of the pain incident to the weight born by an injured or damaged knee. With the brace such patients can move about with safety while healing is taking place. In industry, time ordinarily lost by disabled workers with pre-operative and post-operative knees may be safely cut to the minimum by using the brace, and in some cases the necessity for operative attention may be eliminated by wearing the brace While natural healing takes place.
The brace is especially effective as a protective, as
vwell as a remedial, device for athletes. Pre-season examinations frequently reveal structural weaknesses of the knee from a variety of causes which ordinarily require time consuming and elaborate methods of strapping and bandaging. With the above disclosed type of knee brace, the athlete himself may simply put on and take off the the brace at will, once it has been adjusted tohis knee yby an expert or professional attendant.
As will be apparent to those familiar with the art, the
yinvention may be embodied in other specific forms With- Ajoint when the brace is worn, pressure pads secured to the sleeve on opposite sides thereof, a pair of curved pressure members each of which is secured to one of said pads, said members being hingedly connected and encircling said -joint when the brace is worn, and means at the free ends of said members for releasably securing said ends together to exert pressure on said pads, said members being rigid and being spaced from the joint when the brace is worn whereby there is minimal interference with the circulation in the joint.
