Local expert weighs in on Tiger's injury

Tiger has a torn left ACL, or anterior cruciate ligament. It's one of the four major ligaments in the knee. It's main function is to stabilize the knee during movement.

Tiger reportedly first hurt it ten months ago while running. Then he got a double stress fracture to the shinbone about three weeks ago. But he played through the pain-- many times it showed on his face.

Dr. Robert Frederick of the Rothman Institute at Jefferson said the 91 holes Woods played to the win the U-S Open may have been too much. "Walking multiple rounds of golf on uneven surfaces, could have aggravated symptoms from the stress fracture, in addition to causing the knee to be aggravated due to the ACL," he said.

Dr. Frederick also wonders if Tiger's knee trouble isn't more complicated. "Is there perhaps some other damage within the knee to one of the meniscal shock absorbers, or to the joint surface, which is the articular cartilage? Hopefully, that is not the case," he said.

After surgery, it should take Woods four to six months to get back close to form. That's much quicker than recovery time for football players. Eagles quarterback Donovan McNabb also tore his ACL. It took him a year to recover.
