Abstract
Abstract A knee protector covers the front of the knee, and extends rearwardly on both sides to protect against mechanical damage to the knee. The protector has foamed padding towards the leg for both comfort and mechanical protection, and a somewhat rigid outer shell to provide strength. For comfort as the leg is flexed, the front of the knee protector has a line about which the rigid shell can move, so that two sections of the shell are articulated, allowing movement in all directions. One side of the knee protector can be shortened to allow the use of a knee splint in conjunction with the knee protector.
