Knee dislocations are dangerous. The majority of patients will require fracture treatment as well as ligament replacement. This necessitates a procedure by an orthopedic specialist. In some cases, the injury is so severe that even these procedures may not be enough to correct the problem. In such cases, additional surgeries will be needed. Patients with chronic dislocations may experience pain and arthritis if left untreated. If you're experiencing any of these symptoms, see your doctor immediately. Chronic dislocations are those that have happened more than once. They can become habituated to the joint's position and require extra support from muscles and ligaments to keep them in place. This can lead to increased stress on other parts of the body, especially the hips and knees. Patients may experience pain when walking or standing for long periods of time. In some cases, patients may be given a surgical option for their dislocation. This depends on the severity of the injury and how many times it has previously been done. For example, if you've had one knee replaced and another treated with physical therapy, your doctor may recommend a different course of action this time around.
