Knee cosmesis

A cosmesis for use with a prosthetic knee, comprising:

• a substantially tubular thigh component made of a rubber-like material and having an upper end and a lower end, the upper end resembling at least a lower portion of a human thigh, the lower end comprising a knee-ball section adapted to receive a proximal segment of an endoskeletal knee chassis;
• and
• a substantially tubular shin component made of a rubber-like material and having an upper end and a lower end, the upper end adapted to receive a distal segment of the endoskeletal knee chassis;
• wherein the thigh component and the shin component are are pivotally joined along an axis of rotation that coincides with the axis of rotation of the endoskeletal knee chassis;
• wherein the axis of rotation is located proximally from a distal end of the knee-ball section of the thigh component;
• wherein at least one of the thigh component and the shin component includes at least one hole located along the axis of rotation, the hole receiving an axial member extending between the thigh component and the shin component;
• and
• wherein the upper end of the thigh component is adapted to be rolled onto itself such that the upper end can be rolled down approximate the location where it joins the lower end, and can be thereafter rolled up about a proximal prosthetic limb component and/or patients residual limb.

A cosmesis for use with a prosthetic knee, comprising:

• a substantially tubular thigh component made of a rubber-like material and having an upper end and a lower end, the upper end resembling at least a lower portion of a human thigh, the lower end comprising a knee-ball section adapted to receive a proximal segment of an endoskeletal knee chassis;
• a substantially tubular shin component made of a rubber-like material and having an upper end and a lower end, the upper end adapted to receive a distal segment of the endoskeletal knee chassis;
• a floating knee cap component;
• a first attachment section, a first end of which is joined to the floating knee cap component and a second end of which is joined to the shin component at a fixed point;
• and
• a second attachment section, a first end of which is joined to the floating knee cap component and a second end of which is joined to the thigh component at a variable point;
• wherein the thigh component and the shin component are adapted to be pivotally joined along an axis of rotation that coincides with the axis of rotation of the endoskeletal knee chassis;
• and
• wherein the thigh component can rotate with respect to the shin component.

A prosthetic knee joint, comprising:

• an endoskeletal knee chassis having a proximal segment and a distal segment, the proximal and distal segments being pivotally joined along an axis of rotation;
• a substantially tubular thigh cosmesis component having an upper end and a lower end, the lower end comprising a knee-ball section seating the proximal segment of the endoskeletal knee chassis;
• a substantially tubular shin cosmesis component seating the distal segment of the endoskeletal knee chassis;
• a floating knee cap component coupled between the thigh cosmesis component and the shin cosmesis component;
• a first attachment section, a first end of which is joined to the floating knee cap component and a second end of which is joined to the shin cosmesis component at a fixed point;
• and
• a second attachment section, a first end of which is joined to the floating knee cap component and a second end of which is joined to the thigh cosmesis component at a variable point;
• wherein the thigh cosmesis component and the shin cosmesis component are pivotally joined along an axis of rotation that coincides with the axis of rotation of the endoskeletal knee chassis.
