Abstract
A cosmesis includes a thigh component and a shin component that fit over a prosthetic knee joint. The thigh component and shin component are pivotally joined along an axis of rotation coinciding with that of the prosthetic knee joint. The thigh component and shin component can include internal contours molded into their inside walls to seat the prosthetic knee joint securely therein. The knee ball region of the thigh component can be made relatively thicker to provide a protective cushion and allow the patient to kneel. Additionally, a floating knee cap can be fit over the knee ball area. The upper end of the thigh component can be made of sufficiently thin material to permit rolling onto itself.
Claims21
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 adapted to be pivotally joined along an axis of rotation that coincides with the axis of rotation of the endoskeletal knee chassis.
A prosthetic knee joint, comprising:
- an endoskeletal knee chassis having a proximal segment and a distal segement, 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;
- and
- a substantially tubular shin cosmesis component seating the distal segment of the endoskeletal knee chassis;
- 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.
