Muamba, who turned 24 on April 6, was in cardiac arrest for 78 minutes after collapsing during a March 17 FA Cup game.
“I am naturally very pleased to be discharged from hospital,” he said in a statement released by the hospital. “I would like to take this opportunity to pay tribute to every single member of staff who played a part in my care.
“Now I am out of hospital, I am looking forward to continuing my recovery and spending precious time with my family.”
It is not yet known whether Muamba will be able to resume his playing career.
