A knee dislocation occurs when the bones that form the knee joint are forced out of their normal position. This injury can result from high-impact trauma, such as a car accident or a sports injury. Symptoms often include severe pain, swelling, and an inability to move the knee. Treatment for a knee dislocation typically involves realigning the bones, which may require medical intervention. In some cases, surgery may be necessary to repair damaged ligaments or cartilage. Rehabilitation is essential for restoring function and strength to the knee after the injury.
