Shaun Livingston's Knee Dislocation (2007)

Shaun Livingston's right knee dislocation in 2007 was among the most devastating orthopedic injuries in sports history, as the Clippers guard landed awkwardly and tore his ACL, PCL, and MCL, causing the leg to snap backward. The injury was so severe that doctors initially considered amputation due to the risk of nerve and artery damage; it took 14 months before he could walk again without pain. Livingston's improbable return to the NBA in 2008, culminating in a championship with the Warriors in 2015, is a testament to surgical advancements, but the initial trauma set a benchmark for career-threatening knee injuries.
