Abstract

An orthopedic device includes a first panel defining opposed first and second sides. A second panel has a first end secured to the first side of the first panel along a seam between upper and lower corners of the seam, and a second end defining at least one flap securable to the second side of the first panel at a location site. A first strap has a first end secured to the first side of the first panel and extends from an upper portion of the seam including the upper corner of the seam and overlies at least a portion of the second panel. A dynamic force strap helically extends between upper and lower portions of the orthopedic device and connects to the first panel.

Claims

1. An orthopedic device, comprising:

a first panel defining opposed first and second sides;

a second panel having a first end secured to the first side of the first panel along a seam, and a second end securable to the second side of the first panel at a location site;

a first strap having a first end secured to the first side of the first panel along the seam and overlying the second panel, and a second end securable to the second side of the first panel at the location site a hinge assembly secured to the first panel and extending between upper and lower portions of the orthopedic device, wherein the first strap extends obliquely from the seam and relative to the first panel and a second strap extending from a lower portion of the seam and the first strap extending from an upper portion of the seam at an oblique angle relative to the second strap.

2. The orthopedic device of claim 1, further comprising a dynamic force strap helically extending between upper and lower portions of the orthopedic device and connecting to the first panel.

3. The orthopedic device of claim 1, wherein the seam defines a profile with at least one curved segment, the first strap located along the curved segment.

4. The orthopedic device of claim 1, wherein a lower edge of the first strap extends in a substantially straight direction from the first panel and an upper edge of the first strap extends at an oblique angle relative to the first panel.

5. The orthopedic device of claim 1, wherein a clearance is defined between the first and second straps, the clearance is greatest in height at the seam and tapers in height toward second ends of the first and second straps.

6. The orthopedic device of claim 1, wherein the first strap has a longer length than a length of the second strap.

7. The orthopedic device of claim 1, wherein the second panel defines at least one flap located at the second end, the at least one flap including fastener material for engaging corresponding fastener material located at a second side of the first panel.

8. The orthopedic device of claim 7, wherein the at least one flap includes first and second flaps spaced apart by a gap so that a patella opening is formed in combination with the second side of the first panel.

9. The orthopedic device of claim 8, wherein the second side of the first panel defines first and second projecting portions spaced by a notch combining with the gap to form the patella opening.

10. An orthopedic device, comprising:

a first panel defining opposed first and second sides;

a second panel having a first end secured to the first side of the first panel along a seam between upper and lower corners of the seam, and a second end defining at least one flap securable to the second side of the first panel at a location site;

a first strap having a first end secured to the first side of the first panel and extending from an upper portion of the seam including the upper corner of the seam and overlying at least a portion of the second panel, and a second end securable to the second side of the first panel at the location site;

a second strap having a first end secured to the first side of the first panel and extending from a lower portion of the seam including the lower corner of the seam and having a second end securable to the second side of the first panel at the location site;

a dynamic force strap helically extending between upper and lower portions of the orthopedic device and connecting to the first panel; and

a hinge assembly secured to the first panel and extending between upper and lower portions of the orthopedic device, the dynamic force strap has first and second ends securing to first and second frames of the hinge assembly spaced apart by first and second struts connected to one another by a hinge.

11. The orthopedic device of claim 10, wherein the at least one flap includes first and second flaps spaced apart by a gap so that a patella opening is formed in combination with the second side of the first panel.

12. The orthopedic device of claim 11, wherein the second side of the first panel defines first and second projecting portions spaced by a notch combining with the gap to form the patella opening.

13. The orthopedic device of claim 11, wherein in an open, flat configuration, the first flap is located at least in part above the second end of the first strap, and the second flap is located at least in part above the second end of the second strap relative to the upper corner of the seam, wherein in a closed, wrapped configuration, the first flap is located below the second end of the first strap and borders the patella opening of the orthopedic device.

14. The orthopedic device of claim 13, wherein tensioning of the first and second straps is arranged independently of tensioning of the second panel via the first and second flaps.

15. The orthopedic device of claim 13, wherein when tensioning the first and second flaps to secure to the second side of the first panel, first and second edges of the second panel slope downwardly and upwardly from the upper and lower corners, respectively, toward the second side of the first panel.

16. The orthopedic device of claim 10, wherein the first strap is arranged to be secured to the second side of the first panel independently from the second strap such that the first and second straps are separated by a clearance at the seam.

17. A method for securing an orthopedic device to a leg and about a knee, the orthopedic device including a first panel defining opposed first and second sides, a second panel having a first end secured to the first side of the first panel along a seam and a first strap having a first end secured to the first side of the first panel and extending from the seam, the method comprising the steps of:

placing the orthopedic device in a flat configuration posterior of the knee and leg;

locating the seam along a posterior or a second side of the knee and leg;

wrapping the first panel from the seam about a first side of the leg and knee;

wrapping the second panel from the seam about a second side of the leg and knee;

securing a second end of the second panel to a second side of the first panel;

wrapping the first strap from the seam independently from the second panel and securing a second end to the second side of the first panel and overlying at least part of the second panel.
