Trail Blazers guard Brandon Roy doesn't need to have surgery on his aching left knee.

Doctors determined that the reason Roy's knee has been swelling up to the point where it needed to be drained twice already this season is because there is no cartilage left in the knee.

"Nah. None. Not in my right, either," Roy said.

"The problem is bone-on-bone there," he added. "Dr. [Don] Roberts calls it 'arthritic knee.' It's just something I'm going to have to deal with for the rest of my career."

Roy admitted that there were times this week when he feared that he might need microfracture surgery.
