Your knee relies on a variety of cartilage, ligaments, and tendons to operate properly. A dislocated knee happens when the thighbone's position relative to the shinbone is altered at the knee joint. Trauma to your leg, such as from falls, sports injuries, or vehicle accidents, can cause it. As you get older, you are more likely to experience knee dislocations because of changes that occur within your bones and joints. The most common cause of a spontaneous knee dislocation is also the easiest to prevent: trauma to the leg. If you play sports or have other physical activities in your life, you should know how to give yourself proper protection against injury. For example, if you plan to participate in athletic events such as basketball or soccer, you should be sure to wear appropriate footwear for the conditions. You also need to make sure that you do not engage in activity with your knee bent up under your chest - this places excessive stress on the ligaments and muscles surrounding the joint. If you encounter a situation where giving your knee a good jolt would help reduce pain or prevent further damage, then feel free to jump back into action! However, if you continue to suffer from knee pain even after an injury has healed, see your doctor so that he/she can determine the source of your problem.
