From Kent Somers:
A ruptured patellar tendon is such an unusual injury that a busy orthopedic surgeon might see only a handful of them in a year.
Cardinals running back Ryan Williams suffered one in his right knee on Friday night and is expected to undergo surgery early this week, coach Ken Whisenhunt said.
I was able to reach Dr. Daniel Kharrazi, orthopedic surgeon at the Kerlan-Jobe Orthopaedic Clinic in Los Angeles, to briefly explain the surgery and the rehab timeframe Williams faces.
"The surgery itself is not very difficult," Dr. Kharrazi said. "You basically reconstruct the mechanism that allows you to extend your leg when you run. When the tendon ruptures, it gets a little frayed. You clean up the tendon, drill holes through the patella, or the kneecap, and reattach the tendon."
The hard part comes after surgery. The leg is immobilized in a brace for a month. After the tendon has healed, usually a total of six to eight weeks after surgery, then the patient can begin rehab, Dr. Kharrazi said.
"The No. 1 thing is, when you are in a brace for that long, you have a lot of quadricep atrophy. That's what takes two to three months."
So a patient is looking at "five to six months" between surgery and the time he can return to the level of his previous activity. If all goes well, Williams should be able to return to action in 2012 with no problem, Dr. Kharrazi said.
"I don't think he'll miss a beat," he said.
