16 Claims

1. A patellofemoral support, comprising: a sleeve defining at least two discrete regions having different elastic properties relative to one another, the sleeve having a knee area defining a knee center; a buttress connected to the sleeve and extending about the knee center of the sleeve corresponding to a patella of a user, the buttress having first and second branches extending along opposite sides of the knee center arranged along medial and lateral sides of a patella and proximally from a base located distally of the knee center, the base having an inner curvature corresponding to a general shape of a patella and arranged to abut a distal portion of the patella; a strap system including a helical strap and a circumferential strap, the helical strap is arranged to extend at an angle from a first side of one of a lateral or medial side of the sleeve and to pass over an anterior side of the sleeve to secure to a second side of a lateral or medial side opposite the first side in a distal direction, the circumferential strap extending between at least the first and second sides of the sleeve distally of the base of the buttress and the helical strap, and securing to at least one of the first and second sides without intersecting or overlapping the helical strap; wherein at least a portion of the strap system is arranged to extend over at least part of the first and second branches or base of the buttress and is arranged to exert forces upon the buttress from the first side of the sleeve to the second side of the sleeve generally between medial-to-lateral or lateral-to-medial directions; wherein a free end of the helical strap and a free end of the circumferential strap converge and are joined together by a strap tab, the strap tab carrying the free ends of the helical strap and the circumferential strap to removably connected attach to a plurality of locations within a tab landing area on the second side of the sleeve distal to the knee area, wherein the tab Ian ding area has a larger shape than the strap tab: wherein the helical strap has an anchored end opposite to the free end, anchoring the helical strap to the first side of the one of the lateral or medial sides of the sleeve, the helical strap extending distally at a first location from the first side of the one of the lateral or medial side of the sleeve to the tab landing area at a second location on the second side of the sleeve, the circumferential strap extending from a third location on the first side of the one of the lateral or medial sides to the second location on the second side of the sleeve, the first location being proximal relative to the tab landing area and the third location.
