Abstract
A method and apparatus for the permanent surgical reconstruction of the anterior cruciate ligament in the human knee, which will stabilize the tibia and femur relative to each other and restore a full range of motion to the knee, by precisely locating the ends and angular relationship of a replacement ligament within the knee joint, at bone attachment sites such that the degree of shortening and lengthening experienced by the replacement ligament over the range of joint motion is either as close to zero (isometric) as possible, or closely matches that of the natural uninjured ligament (physometric), whichever the surgeon feels is most desirable.
