Abstract
A cosmesis including 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.
Claims20
A cosmesis for use with a prosthetic knee comprising:
- a substantially tubular thigh component made of a generally flexible 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 shaped to receive a proximal segment of an endoskeletal knee chassis;
- and
- a substantially tubular shin component made of a generally flexible material and having an upper end and a lower end, the upper end shaped to receive a distal segment of the endoskeletal knee chassis;
- wherein the thigh component and the shin component are pivotally joined along an axis of rotation that is adapted to be coupled coaxial with an axis of rotation of the endoskeletal knee chassis.
A prosthetic limb comprising:
- a cosmesis for use with a prosthetic knee joint, the prosthetic knee joint including a proximal segment and a distal segment pivotably joined at a knee joint axis, the cosmesis including
- a generally tubular thigh component made of a flexible material and shaped to receive at least a portion of the proximal segment;
- and
- a generally tubular shin component made of a flexible material and shaped to receive at least a portion of the distal segment;
- wherein the thigh component and the shin component are pivotably joined at a cosmesis axis;
- and
- wherein the cosmesis axis and the knee joint axis are coaxial.
