Richard Berger, an orthopedic surgeon at Rush Medical Center in Chicago who did his residency at Pitt, is a pioneer of a minimally invasive hip and knee replacement technique. He led a 2009 study, published in the journal Clinical Orthopaedics and Related Research, that found that same-day knee replacements require "perfect execution" to be successful. : New Knee Surgery Offers Speedy Recovery, 24 Sept 2004 [cached]
Dr. Richard Berger, an assistant professor of orthopedic surgery at Rush Presbyterian Medical Center in Chicago, is a pioneer of the new technique.He predicts that five years from now, almost all surgeons will be performing the minimally invasive procedure."There's really no downside, only an upside," he said.
Berger estimates that only about 3 percent of orthopedic surgeons in the United States are currently doing the minimally invasive knee procedure.But as more complete the necessary training, they'll jump on the bandwagon, he said.
"At some point almost every orthopedic surgeon is going to be doing this surgery," he said.
No Muscle or Tendon Damage
In traditional knee-replacement surgery, Berger explained, the length of the incision varies, typically between 8 inches to 10 inches."The quadriceps [front of the thigh] muscle is cut or split, the kneecap is flipped over and that exposes the knee.The bone is cut and sized, and the [artificial] knee replacement is put in."
With the new technique, "we make an incision that is 3.5 inches or so," Berger said.
The traditional approach requires 12 to 14 weeks of physical therapy, Berger said.
The hospitalization time with traditional surgery is about four days, Berger said.He said he does the new surgery on an outpatient basis, but other doctors admit their patients to a hospital for the operation.
Not for Everyone
Even advocates such as Bonutti and Berger acknowledge that not everyone is a candidate for the surgery.
People who have already had extensive surgery on their knee may not be good choices, said Berger."And those who are morbidly obese may not be," he said.
But for most patients, the new approach represents a breakthough, Berger said.
Zimmer NexGen Knee Recall Lawyers - $63,000,000 Recovered, 14 Mar 2014 [cached]
Four authors signed onto the report: Hany Bedair, M.D.; Megan Tormey; Craig J Della Valle, M.D.; and Richard A Berger, M.D.
One of the authors, Dr. Berger, had previously tried to convince Zimmer Holdings to fix the problem or remove the product from the marketplace. Dr. Berger felt compelled to criticize the product even though he had made $8 million working for Zimmer, designing surgical tools and devices and training doctors. The company responded to the warnings by punishing the doctor for speaking out. (See New York Times: "Surgeon vs. Knee Maker: Who's Rejecting Whom?")
Because the company refused to act on his warnings, Dr. Berger went public with the information, presenting the "High Failure Rate" report at the annual AAOS meeting. Again, Zimmer refused to heed the warning. Instead, the company released a statement pointing to data from Australia and claiming the product is perfectly safe. However, that same Australian data shows that the Zimmer NexGen LPS has the second highest revision rate of the 20 knee replacement devices listed -- nearly 60% higher than the average.
Although Zimmer ignored Dr. Berger's warnings, United States Senator Charles E. Grassley (R, Iowa) did not.
