A knee is made up of three primary bone fragments called the femora, the patella, and the tibia. The ligaments are parts that might be susceptible to damages and injury to the knees. There are four ligaments in the knee. The knee joint can't be locked in place merely by the bone fragments, the muscles or muscle tissue cells execute an important role to join the knee bone fragments. The cartilage material bones act as a shock absorber for the knees, & abrupt strikes are generally dealt with by this procedure. Moreover, you can find fluid loaded sacs which absorb the external shocks upon the knee.
