Thomas Rosenberg (61), who practices at the Rosenberg Cooley Metcalf clinic in Park City, Utah, a Rocky Mountain ski resort center has operated on the damaged left knee of Tiger Woods
Rosenberg is an early developer of the ``double-bundle'' reconstruction of the anterior cruciate ligament, or ACL.
Most surgeons repair a damaged ACL, which Woods tore, with a single strand of tendon tissue. Rosenberg has pioneered replacing both of the two parts of the ACL. The anterior cruciate ligament guides the knee joint it is believed that the "double-bundle'' reconstruction may preserve the finely tuned ``screw'' action of the knee as it hinges. The perceived advantage of double-bundle surgery is that it restores a more normal motion.''
This is Tiger Wood's fourth knee surgery.
Rosenberg cleaned cartilage from the same joint two months before Woods won the U.S. Open Tournament last week at Torrey Pines Golf Course in La Jolla, California. Woods wound up playing on the hurt knee over five days because of a 19-hole playoff.
The knee joint is similar to a door hinge it lacks the side- to-side flexibility like that of the ball-shaped shoulder joint.
Woods's 125-mile-an-hour swing involves sharp, excessive knee rotation. It is this rotation that can damage ligaments. A golf swing places a lot of rotational torque on a joint that doesn't naturally bend in that direction.
Woods will miss the Open at Royal Birkdale next month and September's Ryder Cup in Valhalla.
In addition to taking time out to recover from his surgery, Woods also requires time off to recover from a double stress fracture of his left tibia that was discovered last month.
