On Jan. 6, millions of NFL fans saw one of the most-talked-about – and most-cringe-worthy – knee injuries in sports history.
During a 2013 wild-card playoff game against the Seattle Seahawks, rookie Washington Redskins quarterback Robert Griffin III fell to the turf after twisting his right knee. Diagnosis: Serious damage to Griffin’s anterior cruciate ligament (ACL), lateral collateral ligament (LCL) and medial meniscus. RG3 underwent three surgeries to fix the knee. Prognosis: Months and months of rehab.
