BONES OF THE KNEE: The femur (thigh bone), tibia (shin bone), patella (knee cap), fibula (smaller bone next to shin bone). Muscles, tendons and ligaments connect the knee bones.The kneecap glides in a groove in the thighbone and adds leverage to the thigh muscles, which are used to extend the leg. The thigh bone and shine bone come together at the knee joint and move on one another when bending or straightening the leg.ENDONS OF THE KNEE: Tendons join muscle to bone. The quadriceps tendon hooks quad muscles to the patella (kneecap); patella tendon connects the patella to the shinbone. The quadriceps tendon and patellar tendon actually connect to form one continuous tendon that covers the patella.
