Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims priority to U.S. Provisional Application Ser. No. 63 / 762,646, filed Feb. 25, 2025, which is hereby incorporated by reference in its entirety including any tables, figures, or drawings.TECHNICAL FIELD

[0002] The present invention relates to a wearable device that can protect the knee joint and upper shin when in contact with a hard surface, such as during work or athletic activities. The wearable device can be particularly useful for protecting the patella and upper tibial area of the lower portion of the knee joint.BACKGROUND OF THE INVENTION

[0003] The human knee joint comprises an area between the distal end of the femur bone in the upper leg and the proximal end of the tibia, or shin bone, in the lower leg. The distal end of the femur has a patellar surface that is overlayed by the patella, which is commonly referred to as the knee cap. The patella is held in place by a patellar ligament that stretches between the femur and a tibial tuberosity that protrudes from the front side of tibia.

[0004] The knee joint is the largest joint in the body and is required for any movement that necessitates flexion or extension of the lower leg, such as running, swimming, biking, squatting, or kneeling. When the knee joint bends or flexes the patella and the tibial tuberosity become anteriorly and prominent and can make contact with a surface that comes into contact with the knee joint. The patella and tibial tuberosity are hard, boney surfaces directly under the patellar ligament, which is just under the skin in the knee joint area. Thus, there is very little tissue between the skin and these boney surfaces, which can make contact with hard surfaces painful and can potentially damage the joint.

[0005] During high-impact sports such as volleyball, basketball, and wrestling, athletes frequently subject their knees to considerable stress through repetitive movements including kneeling, sliding, and falling on hard surfaces. The game of volleyball can be particularly problematic for knee injuries. Players are often required to quickly move or slide into a kneeling position, with one or both knee joints making hard contact with the floor, to reach the ball and then to rise quickly to resume play. This action, among others, creates significant impact on the patella, the tibial tuberosity, and the surrounding tissues, which can result in both acute injuries and chronic conditions if not adequately protected during such contact.

[0006] The current knee protection devices available for volleyball players often lack adjustable or customizable designs that accommodate different body types and individual size variations, particularly in the regions of the lower thigh, knee complex, and upper shin. This one-size-fits-all approach results in poor fit for many athletes, leading to decreased protection and increased discomfort.

[0007] Additionally, conventional knee protection devices concentrate padding almost exclusively over the patella, neglecting the vulnerable lower knee joint and upper shin area where the tibial tuberosity protrudes below the patella in the lower portion of the knee joint. Traditional “knee pads” utilized when playing volleyball, as well as other high-impact sports such as basketball and wrestling, typically focus on cushioning the anterior knee region with compression sleeves having padding concentrated mostly over the patella. This design oversight often leaves the tibial tuberosity and upper shin area exposed to impact injuries. Unfortunately, the design philosophy for knee protection devices has remained largely unchanged for decades, despite significant advancements in materials science and biomechanical understanding of knee injuries.

[0008] The inadequate knee joint coverage and lack of customization provided by existing designs is further compounded by movement issues during athletic activity. Traditional knee pads frequently shift position during intense movements, creating gaps in protection precisely when and where it is most needed. Furthermore, the materials utilized in many existing knee protection products prioritize either impact absorption or mobility, rarely achieving an optimal balance between these competing requirements. This forces athletes to choose between having either adequate protection or a full range of motion, therefore compromising either safety or performance.

[0009] There exists a clear need in the field of knee protection products for a solution that addresses these fundamental limitations while providing enhanced coverage for vulnerable anatomical structures. Such a solution would ideally offer meaningful adjustability to accommodate diverse body types while extending protection beyond the patella to include the often-neglected area just below the knee.BRIEF SUMMARY OF THE INVENTION

[0010] The subject invention successfully addresses the above-described disadvantages associated with known devices and methods, and provides certain attributes and advantages that have not been realized by those known devices. In particular, the subject invention provides novel, cost effective, and highly effective devices and methods for protecting the knee joint area during activities that can require contact with hard or uncomfortable surfaces.

[0011] Embodiments of the subject invention pertain to a wearable device capable of protecting the knee joint area of a person's leg. More specifically, the subject invention provides embodiments of a wearable knee joint protection device that covers the entire knee joint area including the patella and tibial tuberosity therebelow. Advantageously, embodiments of the knee protection device of the subject invention are designed for below-the-knee attachment that can maintain optimal positioning, be more comfortable, and provide advantageous performance during intense athletic movements. In addition, the subject invention is beneficial to anyone who desires protection of the knee joint including the patella and the tibial tuberosity, for example laborers, such as tile installers, whose knees come into contact with hard surfaces such as floors.

[0012] Embodiments of a knee joint protection device according to the subject invention utilize a structural brace specifically designed for below-the-knee positioning, aligning with typical wearing preferences of athletes while providing enhanced protection to the upper shin and tibia (tibial tuberosity)—areas frequently left vulnerable by conventional knee protection solutions. The structural brace can have a front-facing support panel. In one embodiment, a padding or protection mechanism can be removably and securely attached to the front side of the support panel. In another embodiment, the support panel is configured with a pouch in which a padding mechanism can be inserted and the pouch then closed to secure the padding mechanism therein. In alternative embodiments the padding mechanism can be integrally connected to the support panel. In some embodiments a firm or stiff protection mechanism is utilized instead of a padding mechanism. Depending on the degree of stiffness desired by the user, the padding or protection mechanism can be made of any of a variety of suitable materials such as foam, plastic, or even metals or any combination of such suitable materials.

[0013] The knee joint protection device of the subject invention can include a strap system for securing the structural brace to the knee joint area, or it can alternatively be a sleeve-type structural brace in which or on which the padding mechanism can be removably inserted or attached, or to which it is integrally connected. In one embodiment, the structural brace includes lateral panels that extend from each side of a central support panel. Extending from each lateral panel can be a pair of straps that have proximal strap ends that are fixedly attached to the respective lateral panel. The opposite ends of the paired straps, the distal ends extending out from each lateral panel, are operably attached or integrally connected to form a joined end that forms an angle between the straps of each pair, which provides a gap between the joined end of each pair of straps and the respective lateral panel.

[0014] To wrap the knee joint protection device to the lower leg, ideally just below the bend or crease in the knee joint, the structural brace can be placed against the knee joint, with an extended lower end of the support panel covering the tibial tuberosity. The lateral panels can be folded around the sides of the knee joint. The joined end of one pair of straps can be passed through the gap in the opposite pair of straps, such that the straps are interlaced. Each set of paired straps can then be pulled around the leg to bring the joined end around to the lateral panels on each side of the knee joint. The joined end can further have an anchorage, such as, for example, hook-and-loop material or another type of touch fastener, which can be securely attached to anchor points that are preferably on the lateral panels to secure the knee joint protection device on the leg. The configuration of the straps of the strap system is such that in preferred embodiments when the straps are attached to this respective anchor points the secured straps rest below the user's knee crease at the top of the calf and can optimize fit across diverse body types while maintaining the position of the knee joint protection device during athletic movements. This can ensure that the knee joint protection device is in an optimal position to provide maximum protection, at all times, during use.

[0015] In a further embodiment, the support panel of the structural brace has a removable padding mechanism. In one embodiment, the padding mechanism can be removably attached to a securing device arranged on a front side of the support panel. In an alternative embodiment, the support panel comprises a pouch in which the padding mechanism is inserted and secured when the pouch is closed.

[0016] The invention provides several key advantages over existing solutions. First, it offers meaningful adjustability that addresses the limitations of one-size-fits-all products currently dominating the market. Second, the extended coverage below the knee crease and over the tibial tuberosity provides protection to anatomical regions typically neglected in standard designs. Third, the system maintains optimal positioning during intense athletic movements, ensuring effective protection when and where it is most needed.

[0017] The invention can also address practical usability concerns through appropriate design choices. For example, the materials and construction methods can be selected for durability, flexibility, and comfort, while the adjustable components provide adaptability across different usage scenarios and user preferences. In preferred embodiments, the system includes a removable and replaceable padding mechanism that enhances product longevity while allowing customization of protective elements. Users, such as, for example, athletes, can easily replace just a worn padding mechanism rather than an entire unit, improving cost-effectiveness and reducing waste. Additionally, the removable padding mechanism can facilitate cleaning of the adjustable components periodically as desired.

[0018] The present disclosure represents a significant advancement in athletic protection technology, offering a practical and anatomically informed solution to the long-standing challenges in this field. The invention's combination of adjustable fit, extended coverage, and replaceable, customizable components positions it as a viable solution for enhanced safety across multiple athletic disciplines.BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The subject invention pertains to embodiments of a wearable device for the protection of the knee joint. More specifically, the subject invention provides one or more embodiments of a knee joint protection device capable of providing protection covering at least the tibial tuberosity and the patella.

[0033] The following description will disclose that the subject invention is particularly useful during athletic sports, such as volleyball and wrestling, where the knee joint can make intense contact with a hard or otherwise uncomfortable surface. While the subject application describes, and many of the terms herein relate to, a use for protecting the knee joint during athletic activities, other activities could also benefit from the embodiments disclosed herein. Thus, any modifications that would be apparent to a person with skill in the art and having benefit of the subject disclosure for uses other that those disclosed herein are contemplated to be within the scope of the present invention.

[0034] In the description that follows, a number of terms are utilized related to the subject invention and methods of use. In order to provide a clear and consistent understanding of the specification and claims, including the scope to be given such terms, the following definitions are provided.

[0035] As used herein the term “knee joint” refers to an area of the human leg including the lower end of the femur and the upper end of the tibia. More specifically, the term refers to the area of the leg between and including the tibial tuberosity on the tibia bone and the patella, located in front of the patellar surface of the femur.

[0036] Also, as used herein, and unless otherwise specifically stated, the terms “operable communication,”“operable connection,”“operably connected,”“cooperatively engaged,”“operably attached,” and grammatical variations thereof mean that the particular elements are connected in such a way that they cooperate to achieve their intended function or functions. The “connection” or “engagement” may be direct, indirect, or remote.

[0037] Reference to the term “substantially” herein means the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or result. For example, an object that is “substantially” in a given position including but not limited to vertical, horizontal, or adjacent to or aligned with another object, would mean that the object is either completely in that position or nearly completely in that position. The exact allowable degree of deviation from absolute completeness may in some cases depend on the specific context. However, generally speaking the nearness of completion will be so as to have the same overall result as if absolute and total completion were obtained.

[0038] The terms “about” or “approximately,” as used herein, are defined as at least close to a given value or to either end of a range. For example, these terms can indicate that a characteristic, parameter, or value is as close as is necessary to achieve the intended purpose or operation, or to cover manufacturing variances, equipment tolerances, and normal variances in material, or substances, as would be understood by those skilled in the art. For numerical ranges, this is commonly ±10%.

[0039] As used herein, terms indicating relative direction or orientation, including but not limited to “upper”, “lower”, “top”, “bottom”, “vertical”, “horizontal”, “outer”, “inner”, “front”, “back”, “left”, “right” and the like, are intended to facilitate description of the present invention by indicating relative orientation or direction in usual use, and are not intended to limit the scope of the present invention in any way to such orientations or directions.

[0040] Furthermore, the subject invention is more particularly described in the following examples that are intended to be illustrative only because numerous modifications and variations therein will be apparent to those skilled in the art. As used in the specification and in the claims, the singular for “a,”“an,” and “the” include plural referents unless the context clearly dictates otherwise.

[0041] Any reference in this specification to “one embodiment,”“an embodiment,”“example embodiment,”“further embodiment,”“alternative embodiment,”“select embodiment,” etc., is for literary convenience. The implication is that any particular feature, structure, or characteristic described in connection with such an embodiment is included in at least one embodiment of the invention. The appearance of such phrases in various places in the specification does not necessarily refer to the same embodiment. In addition, any elements or limitations of any invention or embodiment thereof disclosed herein can be combined with any and / or all other elements or limitations (individually or in any combination) or any other invention or embodiment thereof disclosed herein, and all such combinations are contemplated with the scope of the invention without limitation thereto.

[0042] Finally, the description herein of any aspect or embodiment of the invention using terms such as “comprising,”“having,”“including,” or “containing” with reference to an element or elements is intended to provide support for a similar aspect or embodiment of the invention that “consists of,”“consists essentially of,” or “substantially comprises” that particular element or elements, unless otherwise stated or clearly contradicted by context (e.g., a composition described herein as comprising a particular element should be understood as also describing a composition consisting, or consisting essentially, of that element unless otherwise stated or clearly contradicted by context). Use of the term “comprising” contemplates other embodiments that “consist” or “consist essentially of” the recited component(s).

[0043] It is to be understood that the figures and descriptions of embodiments of the present invention have been simplified to illustrate elements that are relevant for a clear understanding of the invention, while eliminating, for purposes of clarity, other elements that may be well known. Those of ordinary skill in the art will recognize that other elements may be desirable and / or required in order to implement the present invention. However, because such elements are well known in the art, and because they do not facilitate a better understanding of the present invention, a discussion of such elements is not provided herein.

[0044] The components of a knee joint protective device of the subject invention can comprise any suitable material or combinations thereof. The factors to be considered for the choice of one or more materials for manufacture of the embodiments of the protective device of the subject invention would be understood by those skilled in the art. Accordingly, the subject invention is not limited to any particular material(s) or combination thereof. Ideally, the one or more selected material(s) will have appropriate padding, a modulus of elasticity, flexibility, shape, and dimensions that are optimized to secure the knee joint protective device when being worn and protect the knee joint during use.

[0045] Set forth below is a description of what is currently believed to be the preferred embodiment or best example of the invention claimed. Future and present alternatives and modifications which make insubstantial changes in function, in purpose, in structure, or in result are intended to be covered by the claims of this patent. Where alternative meanings are possible, the broadest meaning is intended. All words used in the claims are intended to be used in the normal, customary usage of grammar and the English language.

[0046] Reference will be made to the attached Figures on which the same reference numerals are used throughout to indicate the same or similar components. With reference to the attached Figures, which show certain embodiments of the subject invention, it can be seen in FIG. 1 that a “Knee Joint Protective Device”100 of the subject invention is a wearable device that comprises a structural brace 106 capable of being wrapped around at least a portion of a knee joint 50, as defined above. The structural brace can include a support panel 112 and lateral panels 120 extending from each lateral side 111 thereof. A strap system 130 can be incorporated with the lateral panels and utilized to secure the structural brace to a leg, thereby covering and protecting a knee joint. A strap system can include a pair of elongated straps, an upper strap 132 and a lower strap 134, which are fixedly attached to and extend away from a lateral edge 122 of each lateral panel. The paired straps can be interlaced with each other allowing each pair to be pulled around the leg in opposite directions and attached to the structural brace. A padding mechanism 102 can be incorporated with the support panel to provide further protection for the knee joint 50. Each of these general components can have one or more sub-components, which will be discussed in detail below.

[0047] With reference to FIG. 1, it can be seen that the knee joint protective device 100 (henceforth, referred to as the “protective device 100” for brevity) can include a structural brace 106. In one embodiment, the structural brace comprises a centralized support panel 112 and lateral panels 120 that extend from lateral sides 111 of the support panel. The structural brace can be configured to be placed in front of or anterior to the leg to cover the knee joint, as shown, for example, in FIGS. 3A, 3B, 5 and 6. Embodiments of the structural brace have a shape and configuration that provides a “zone of protection”104 that covers the knee joint when the leg is in either a flexed or extended position, which is shown, for example, in FIGS. 3B and 5.

[0048] The structural brace can include a pouch 114 in which a padding mechanism 102 can be arranged and secured, as shown, for example, in FIGS. 4A-4C, to provide further protection to the knee joint 50. In one embodiment, the structural brace 106 can comprise at least two layers of material that are coupled, connected, or otherwise attached to form a contact layer 108 on the back side 30 of the structural brace and a cover layer 107 on the front side 25 of the structural brace. The two layers can be attached by any device or technique known to those with skill in the art, including, but not limited to, stitching or heat sealing. In one embodiment, one or both of the layers have padding or comprise a material having padding characteristics. Thus, the structural brace, when worn, can provide protection to the knee joint. As discussed further below, the structural brace with or without the padding mechanism can provide a “zone of protection 104” that covers the knee joint.

[0049] In a further embodiment, the support panel 112 can have a pouch 114 formed between the contact layer 108 and the cover layer 107. The pouch can have an opening 115 through which a padding mechanism 102 can be inserted and secured therein, a non-limiting example of which is shown in FIGS. 4A-C. The opening can be closed and secured by any of a variety of devices and techniques known to a person of skill in the art. Ideally, the opening can be secured by a temporary or reusable device that allows for repeated opening and closing of the opening.

[0050] In one embodiment, a flap 117 is operably positioned in the area of the opening 115. The flap can be folded or bent over the opening and secured to maintain the padding mechanism in the pouch. In an embodiment, the cover layer 107 has a flap 117, near an opening at the lower end 10, which can be folded or bent over to attach to the contact layer 108. The flap can be secured to the outside of the contact layer 108, but, in a preferred embodiment, is secured to the contact layer on the inside of the pouch, as shown, for example in FIGS. 4A-C. FIGS. 2A, 2B and 4A-4C illustrate a stay mechanism 118 having a first component 118A on the flap 117 and a second component 118B on the contact layer 108, such as on the inside of the pouch. In a specific embodiment, the stay mechanism comprises a touch fastener, such as, for example, hook-and-loop material, operably attached to the flap and to the contact layer. When the flap is folded or bent the first component cooperatively engages with the second component.

[0051] In another embodiment, shown in FIG. 2B, a support layer 116 of material is affixed to either a front side 25 or a backside 30 of the structural brace, in alignment with the support panel, 112 to form a pouch 114 on the structural brace. Thus, the support layer does not extend over the entire structural brace, as with the above-described embodiments. With this embodiment, an opening 115 can be provided, as described above, for inserting the padding mechanism 102 into the pouch between the supporting layer and the support panel. Either the support panel or the support layer can be configured with a flap 117. A stay mechanism can be utilized, as described above, to close the opening, and secure the padding mechanism 102. In a further embodiment, the support layer can comprise a padding material with sufficient impact resistance to provide protection to the knee joint. This embodiment allows the structural brace to be utilized without a padding mechanism and still protect the knee joint.

[0052] There can be activities or situations where it would beneficial if the padding mechanism 102 could be quickly removed or replaced on a structural brace 106. In some situations, it could also be helpful to have the ability to remove or replace a padding mechanism while the structural brace is still wrapped around the knee joint. FIGS. 5, 7, and 8 illustrate an embodiment comprising a structural brace 106 with a padding mechanism 102 arranged on the front side 25 of the support panel 112 thereof. This embodiment has an attachment device 103 that can be utilized to operably connect the padding mechanism to the support panel. A person of skill in the art would be able to determine the preferred or optimal attachment device 103 from any of a variety of attachment devices known in the art. By way of a non-limiting example, the padding mechanism and support panel can have compatible hook-and-loop strips that can be engaged to operably connect the padding mechanism to the front side 25 of the support panel. FIG. 7 illustrates an embodiment of a structural brace with a component of an attachment device 103. FIG. 9 illustrates an embodiment of a padding mechanism that can be attached to the front side of the support panel. FIG. 10 illustrates an embodiment of a padding mechanism with another component of the attachment device arranged on the backside 30.

[0053] Embodiments of the subject invention also provide a padding mechanism 102 that is advantageously independent of the joint protector. This independence allows the padding mechanism to be removed, exchanged, or otherwise separated from the structural brace 106. Likewise, as discussed above, the structural brace 106 can be utilized without the padding mechanism. In one embodiment, the padding mechanism comprises one or more padding materials capable of protecting the knee joint. It is within the skill of a person trained in the art to determine the appropriate one or more padding materials for a padding mechanism and such variations are within the scope of the claimed invention. In a specific embodiment, the padding mechanism comprises a foam or foam-like material that is sufficiently flexible to be inserted through an opening 115 in the pouch 114. In a further embodiment, the padding mechanism has a shape and dimensions that provide a “zone of protection”104, examples of which are shown in FIGS. 3B and 5, which encompasses the upper shin and tibial tuberosity areas of the knee joint. This zone of protection represents a fundamental design advancement that positions the primary protective elements in the most vulnerable areas of the knee joint, which can protect the wearer during high-impact activities. In one embodiment, shown in FIGS. 1, 4A, 5, and 9, a portion at the upper end 5 of the padding mechanism is wider between the left side 15 and the right side 20 than a portion at the lower end 10. Stated another way, a portion of the padding mechanism at or near the upper end flares outward so as to be wider than a portion at or near the lower end 10.

[0054] In preferred embodiments the padding mechanism 102 and structural brace 106 are configured such that a majority of the surface area or volume of the padding mechanism 106 sits below a user's knee crease to protect the tibial tuberosity and upper shin bone, while the upper extension 5 of the padding mechanism fits above the knee crease to protect the patella.

[0055] Any knee pad protection is only effective when it covers the knee joint and remains in place during intense activity. Many of the knee protection devices known in the art utilize straps, wraps, or combinations thereof that are attached above and below the knee joint. There are myriad reasons why this is suboptimal—notwithstanding the discomfort and reduced flexibility around the knee joint.

[0056] The subject invention has three key advantages that address these issues. The first is that it provides meaningful adjustability and foregoes the current “one-size-fits-all” ethos. The second is the more complete coverage of the knee joint, which includes not only the patellar region but also covers the tibial tuberosity. The third is devices and methods for attachment that maintain optimal positioning during intense athletic movements, ensuring consistent protection when it is most needed.

[0057] The protective device 100 of the subject invention can utilize a strap system 130 that goes at least partially around the leg and engages with anchor points 125 arranged on the lateral panels 120. Advantageously, the strap system can securely attach the protective device 100 to the lower leg area just below the knee crease. This allows for positioning over the tibial tuberosity and for the padding mechanism to extend upwards to fully cover the patellar region of the knee joint, thereby providing a zone of protection 104, an example of which is illustrated in FIGS. 3A, 3B, and 3C. As depicted here, a majority of the padding mechanism is positioned below the knee crease. Advantageously, the device of the subject invention is configured to be secured around or on the upper calf region below the popliteal fossa, rather than directly over the popliteal fossa. This placement avoids pressure on the back of the knee, reduces friction behind the knee, and preserves full range of motion during athletic activity.

[0058] In one embodiment, a strap system employs a first and a second pair of elongated straps, each pair having an upper strap 132 and a lower strap 134, which have strap ends 135 fixedly attached to attachment points 124 on the lateral panels 120 and extend away from a lateral edge 122 of each lateral panel. The attachment points can be reinforced by techniques known to those with skill in the art. In one embodiment, shown in FIGS. 1, 3A, 4A-4C, and 8, the upper strap 132 has a strap end 135 that is operably attached to an attachment point at or near an upper end 5 of a lateral panel 120, and the lower strap 134 also has a strap end 133 that is operably attached to another attachment point 124 at or near a lower end 10 of a lateral panel.

[0059] In a further embodiment, the opposite ends of the upper strap 132 and the lower strap 134 can be integrally connected, as shown in FIGS. 11 and 12, or are fixedly attached to each other, such that there is a joined end 136, as shown, for example, in FIGS. 1, 3A, 7, and 11. Thus, each of the paired elongated straps form an angle (A) therebetween that provides an advantageous opening or gap 137, as shown, for example, in FIGS. 1, 4A, 7, and 12. In one embodiment, the angle (A) formed between the upper strap and the lower strap is between about 20° and about 30°. In a specific embodiment, the angle (A) formed between the upper strap and the lower strap is between about 23° and about 28°. FIG. 1 illustrates an embodiment where the lower strap is angled upwards relative to the horizontal. FIG. 7 illustrates another embodiment with a horizontal lower strap.

[0060] Ideally, the material utilized for a strap has at least some elasticity. In one embodiment, the straps comprise an elastic or elasticized material. In another embodiment, the straps comprise more than one type of material wherein at least one has elastic properties. In a still further embodiment, each strap of a pair of straps can have different characteristics. For example, one strap of a pair of straps can comprise an elastic material that is in some way different from the elastic characteristics of material of the other strap of the paired straps.

[0061] The joined ends 136 of the upper straps 132 and the lower straps 134 of the strap system 130 can have anchorage 138 thereon that allows them to be operably attached an anchor point 125 provided on the front side 25 of each lateral panel 120 to maintain optimal positioning during athletic movements. In one embodiment, the anchor point 125 is between the attachment points 124 where the opposite ends of the straps are fixedly attached to the anchor points 125 on the lateral panels 120. FIGS. 3A and 5 demonstrate how the structural brace 106 with the padding mechanism 102 engaged with the structural brace 106 can form an integrated unit that can be secured to a leg with the strap system.

[0062] The attachment of a knee joint protective device 100 to a leg is shown in FIGS. 3A, 3B, and 3C. With reference to FIGS. 3A-3C, it can be seen that a method for placing and wearing a knee joint protective device on a knee joint can include at least the following steps:

[0063] 1. Place the back side 30 of the protective device against the anterior of the knee joint with the zone of protection 104 over the tibial tuberosity and the patella.

[0064] 2. Direct, by folding or bending, the lateral panels toward the sides of the knee joint.

[0065] 3. At the back of the leg, insert the joined end 136 of the first pair of straps through the gap 137 in the opposite second pair of straps, such that the strap pairs are interlaced.

[0066] 4. Pull the joined ends of both pairs of straps around the leg, with first pair of straps extending through the gap of the second pair of straps and over the front sides 25 of the lateral panels 120, ensuring the straps are around the lower part of the leg, below the knee crease where the knee joint bends.

[0067] 5. Cooperatively connect the anchorage 138 of the joined ends to the anchor point 125 on respective the lateral panels 120.

[0068] These minimal steps can ensure that embodiments of the knee pad protection device 100 of the subject invention are properly positions for maximum protection. Additional steps can include, but are not limited to: arranging the position of the upper straps 132 and lower straps 134 to lay as flat possible against the leg and each other and ensuring the appropriate padding mechanism is engaged with the structural brace prior to attaching to the leg.

[0069] Embodiments of the knee joint protection device of the subject invention provide customizable protection that is particularly beneficial for athletes, particularly during high-impact court sports such as volleyball. The knee joint protection device can provide an innovative design system that allows for personalized fit options, as well as customization and replaceability of the pad utilized with the knee protection device. These features provide comfort as well as protection beyond that realized by traditional “knee pads” currently available in the market.
