Is a dislocated knee an emergency?
A knee dislocation is an emergency medical situation that can potentially damage any or all of the structures in your knee. The shinbone, kneecap, and thighbone are knocked out of their normal positions by a direct, traumatic force.
How serious is a dislocation?
Most dislocations don’t have serious or lasting complications. When the bones that make up a joint slide out of place, it can cause the tendons, ligaments, and muscles around the joint to tear. It may also sometimes cause bones to break. Your doctor may recommend surgery to repair these injuries.

About half of knee dislocations will reduce or realign themselves spontaneously. The bones may look aligned, but the joint remains very unstable. The patient will have too much pain to lift the leg off the stretcher or to try and walk at all.
Is dislocation worse than breaking?
Dislocated joints, unless they are realigned quickly, are more likely to damage blood vessels and nerves than are fractures. Some complications (such as blood vessel and nerve damage and infections) occur during the first hours or days after the injury.
What can happen if dislocations are left untreated?

What is a knee dislocation and how serious is it?
A knee dislocation is an uncommon but extremely serious injury in which the thigh bone (femur) and shin bone (tibia) lose contact with each other. A knee dislocation is different from a patellar dislocation in which only the kneecap is detached from its groove at the end of the femur. Terje Rakke / Getty Images
How do you treat a dislocated knee in the emergency department?
The management of dislocations in the emergency department firstly requires immediate reduction of the knee joint, ideally as a closed procedure. A rapid neurovascular assessment is then performed. In posterolateral dislocations, a closed reduction may be impossible, in which case an open reduction is necessary 2 .
What are the chances of amputation from a dislocated knee?
If a vascular obstruction is left untreated for more than eight hours, the chance of amputation is 86 percent compared to 11 percent if treated within eight hours. Knee dislocations are often the result of a high-impact injury such as an automobile crash, severe fall, and sports injuries.
What is the difference between a patellar and knee dislocation?
A knee dislocation is different from a patellar dislocation in which only the kneecap is detached from its groove at the end of the femur. The most common symptoms of knee dislocation are the visible swelling and deformity of the knee joint.
