A 28-year-old obese gentleman is brought to the emergency department by EMS with knee pain and swelling. He missed a step while going down the stairs and landed awkwardly on his leg which caused immediate pain, swelling, and inability to weight bear. Currently his knee appears in the correct anatomic position but is significantly bruised and swollen with gross joint instability. Dorsalis pedis and posterior tibial pulses are present. You are considering a knee dislocation. Which is true about this diagnosis?
