The 24-year-old missed the whole of last season as he continued his recovery from an injury he suffered in April 2012, but he is expected to be fully fit for the beginning of the new campaign.
"I feel [like I'm] back," Rose told reporters. "I'm not worried about anything.
"I'm reacting when I'm out there, just trying to win every scrimmage and just trying to push everybody to be better.
"I got confidence in my knee. There's no testing anymore. It's me just going out there and playing hard and attacking."
Rose was named the NBA's MVP in 2011.
