Dislocation of the knee is usually caused by a traumatic injury, such as a fall, a motor vehicle accident, or a sport-related injury. It can also be caused by a medical condition such as osteoarthritis, rheumatoid arthritis, or a birth defect.
Diagnosis of a knee dislocation is typically made through physical examination, X-rays, and/or MRI scans.
Differential diagnosis of a knee dislocation includes a tear in the knee ligaments, a fracture in the knee, and/or a meniscal tear.
Treatment for a knee dislocation typically includes immobilization of the knee, medications for pain and inflammation, and physical therapy. If a ligament or bone has been damaged, surgery may be necessary.
The prognosis for a knee dislocation is generally good. With proper treatment and rehabilitation, the majority of patients are able to return to their normal activities.
