Disposable instruments debut for orthopedic surgery

MARTINS FERRY, Ohio - Orthopedic surgeries will now be more sterile and precise, thanks to some state-of-the-art technology in the operating room.


Monday at East-Ohio Regional Hospital, doctors were the first to use disposable instruments for a certain type of knee surgery.

The tools that they are referring to as instruments are replicates of the implants. Surgeons use them for a trial of the actual implant prior to the actual inserting of the replacement,a technique that they continue to use and improve upon.

"I think it's definitely an improvement over what we have. It's definitely a patient-specific trial that we're doing, a trial made just for that patient,"
Dr. Jack Michalski said. "It's definitely light years ahead of what we have, but I'm looking, again, for a bright future."

According to hospital officials,
Michalski was the first surgeon in the Ohio Valley to use the 30-year knee implant with a knee replacement. Now, he becomes the first in the United States to use disposable instruments for arthroscopic knee surgery.

The new instruments allow for an increase in comfort and precision during surgeries and also cut down on the risk of infection for patients.


Doctors make a template using a magnetic resonance imaging scan and weight-bearing film for the surgery.


"They (patients) are able to get up the same day walking, putting their full weight on it. They're able to start with their motion machines right away," Michalski said. "They're able to get back to their normal activities, which is what everybody wants, and for a lot of people, even advancing to the next level and being able to do more than they could before their prior knee replacement."


The instruments are built out of composite, inert materials, which means that it will not interfere with the patient. It's also specifically designed for that patient and will only be used once.


"They're not going to fit on Mrs. Jones, Mr. Smith, they're going to fit directly on you," Michalski said. "That is definitely a leap ahead. It can make our surgery more precise (with)
less bleeding, quicker rehab time and less muscle problems for the patient."
