Richard Berger, M.D.
An extremely busy clinician and master technician, Dr. Berger provides the fellowship with a wealth of clinical material. His practice emphasizes less invasive surgical techniques and he is a pioneer in the development of perioperative pathways to optimize patient outcomes. His research interests include clinical outcomes of both less invasive primary and complex revision procedures. Dr. Berger performs a substantial volume of partial knee arthroplasties (including unicompartmental and patellofemoral arthroplasty) and unique surgical exposures.

Dr. Richard Berger, an orthopedic surgeon at Rush University Medical Center and a pioneer in minimally invasive hip and knee replacement surgery techniques, points out that only three out of 10 people who would benefit from hip or knee replacement surgery and have insurance to cover the procedure actually seek treatment.
In June 2012, Berger performed a less invasive knee replacement on Mattson's left knee. "The difference between the last time…and this time is so amazing," she says.

But hip and knee replacements with ..., 7 April 2011 [cached]
But hip and knee replacements with Dr. Richard Berger, orthopaedic surgeon at Midwest Orthopaedics at Rush and assistant professor of orthopaedics at Rush University Medical Center, are anything but typical.
A pioneer of minimally invasive joint replacement surgery, Dr. Berger performs surgeries on an outpatient basis. A few hours after they emerge from the operating room, his patients typically walk 200 feet around the nurse's station, climb up and down a flight of 15 stairs, and then go home the same day.
With his minimally invasive approach to knee surgery, Berger makes a small 3- to 4-inch incision, without cutting through muscles, tendons and ligaments, so patients can recover faster. The recovery time is shorter, which enables patients to move their leg as quickly as possible before scar tissue builds up.
Dr. Berger has used his mechanical engineering background to develop surgical tools that enable him to maneuver around a patient's muscles and tendons to reach the arthritic bone. Then he carefully removes small pieces of the bone until he gradually has enough space to implant the new prosthesis, which is the same type of prosthetic used in standard total joint replacements.
With Dr. Berger's minimally invasive approach, patients have less time in the hospital and are able to regain motion much more quickly.

Assistant Professor,
Rush University Medical Center
Dr. Berger has pioneered minimally invasive hip and knee replacement, allowing patients to recover faster with less pain than patients undergoing traditional hip and knee replacement surgery. His surgery is unique because of his advanced techniques which allow him to perform the surgery without cutting any muscle, ligaments or tendons, on the patient. These advances allow most of Dr. Berger's patients to walk independently and leave the hospital the same day of surgery. His mechanical engineering background has also helped him to design gender-specific implants that fit and perform better for active patients Meet Our Team

One of the surgeons, Richard Berger, M.D., was a consultant for Zimmer for more than a decade, receiving more than $8 million for his services. In the Times article, Berger said he implanted Zimmer's NexGen CR-Flex device in about 125 patients in 2005. Though the device is supposed to last 15 years, Berger noticed that some X-rays showed lines where the implant met the thigh bone, an indication that the artificial knee had not fused completely. Patients were able to walk, but experienced pain, he told the Times. In a study he conducted with another doctor, Berger found the uncemented NexGen knee failed early in about 9 percent of 100 patients. In addition, the study concluded, Zimmer's knee showed signs of loosening in about half of all patients and has been replaced in some of them.
Berger alerted Zimmer executives to the problem (including the company's top scientist), but the company countered those failures in a filing with the U.S. Securities and Exchange Commission.
