The multiple-ligament injured knee is a complex problem in orthopedic surgery. It may present as acute knee dislocation and careful assessment of the extremity’s vascular status is essential because of the possibility of arterial and/or venous compromise. These injuries requires a systemic approach for evaluation and treatment .The physical examina¬tion is important to determine the extent and pattern of injury, as well as to recognize potentially limb-threatening injuries that may require emergent intervention. Imaging studies enable the surgeon to make a correct diagnosis and formulate a treatment plan. Although most patients are sur¬gical candidates, the decision to proceed with operative management is patient dependent and multiple factors must be considered. The goals of rehabilitation are to protect the repair and facilitate functional knee motion and strength.
