PHOENIX -- Four-time NL Cy Young Award winner Randy Johnson underwent successful arthroscopic knee surgery, his first operation in seven years.
Johnson had tests on his right knee about two weeks ago, and the decision to operate was made after a second test showed loose particles causing inflammation in the left-hander's knee.
Doctors removed the particles in a brief operation and drained fluid from the knee. Johnson, who will be on crutches for a few days before beginning rehabilitation, is expected to miss three-to-six weeks.
