 Questions and Answers about Knee Problems
The knee joint is the junction of three bones -- the femur (thigh bone or upper leg bone), the tibia (shin bone or larger bone of the lower leg), and the patella (kneecap).
Separating the bones of the knee are pads of connective tissue called menisci, which are divided into two crescent-shaped discs positioned between the tibia and femur on the outer and inner sides of each knee.
Injury to the cruciate ligaments of the knee is sometimes referred to as a "sprain." The anterior cruciate ligament is most often stretched, torn, or both by a sudden twisting motion (for example, when the feet are planted one way and the knees are turned another way).

A magnetorheological knee prosthesis is developed that automatically adapts knee damping to the gait of the amputee, using only local sensing of knee force, torque, and position.
