Your knee is made up of many important structures, any of which can be injured. The most common knee injuries include fractures around the knee, dislocation, and sprains and tears of soft tissues, like ligaments. In many cases, injuries involve more than one structure in the knee.
Pain and swelling are the most common signs of knee injury. In addition, your knee may catch or lock up.
A dislocation occurs when the bones of the knee are out of place, either completely or partially. the femur and tibia can be forced out of alignment, and the patella can also slip out of place. Dislocations can be caused by an abnormality in the structure of a person's knee. In people who have normal knee structure, dislocations are most often caused by high energy trauma, such as falls, motor vehicle crashes, and sports-related contact.
Ligaments tear can be caused by sudden twisting motion
Types of knee injuries
A knee sprain occurs when one or more ligaments in your knee are suddenly stretched or torn.
Knee joint dislocation
occurs when the bones that form the knee are out of place. A knee dislocation, more specifically, is when the bones of the leg (the tibia and fibula) are moved in relation to the bone in the thigh (femur)
A knee fracture is a break or crack in 1 or more of the bones in the knee joint. It may be just a bend or small crack in the bone, or the bone may break into pieces or shatter. Some fractures may stick out through the skin.
