In a game against the Charlotte Bobcats on February 26, 2007, Livingston suffered a debilitating knee injury, dislocating his left kneecap after landing awkwardly following a missed layup, resulting in the left leg snapping laterally. Livingston injured almost every part of his knee, tearing the anterior cruciate ligament (ACL), the posterior cruciate ligament (PCL), and the lateral meniscus, badly spraining his medial collateral ligament (MCL), and dislocating his patella and his tibio-fibular joint. Livingston was told by a medical professional at the hospital that there was a chance that his leg would have to be amputated. He required months of rehabilitation to be able to walk again. Livingston was also riddled by injuries during the first three years of his professional career, and missed 101 of 246 regular season games.
