Why a Dislocated Knee Is Always an Emergency | Orthopedic Surgeon Explains

Knee Dislocation: The Knee Injury That Can Threaten Your Leg #shorts A knee dislocation is not a bad sprain, and it is not a dislocated kneecap. It is a limb-threatening emergency, and must be taken seriously. In a true knee dislocation, the thighbone (femur) and shinbone (tibia) separate - several major stabilizers usually tear at once: the ACL and PCL, often along with the MCL, LCL, and the posteromedial or posterolateral corner. Most occur with high-energy trauma such as car crashes, dashboard impacts, and falls from a height. Sports injuries can cause them too, and in some patients even a low-energy misstep is enough. . The real danger sits directly behind the knee - your popliteal artery. This main blood supply to the lower leg, is tethered above and below the joint, so it can stretch, tear, or clot when the bones shift. The peroneal nerve, which lifts the foot and ankle, is also vulnerable, and injury can lead to foot drop. Many #kneedislocations pop-back into place before anyone reaches the hospital, so the knee may look almost normal. A palpable pulse in the foot doesn't rule-out an artery injury either, because smaller vessels around the knee can mask it. That is why emergency teams check blood flow repeatedly, often with an ankle-brachial index, ultrasound, or CT angiography Treatment starts with prompt realignment and a vascular assessment, followed by stabilization, ligament reconstruction in most cases, and dedicated rehabilitation. If a knee injury comes with gross instability, a cold or pale foot, numbness, or trouble lifting the foot, call 911.
