Rochester, Indiana — Dr. Jeffrey Sheedy, an orthopedic surgeon on the Woodlawn Hospital Medical Staff, recently performed the first “custom-fit knee” replacement surgery at Woodlawn Hospital, Rochester, Indiana.  The Zimmer Patient Specific Instrumentation combines advancements in instrumentation technology with proven orthopedic alignment principles.

No two knees are alike.  The real advantage of the PSI knee is the custom-fit for each patient’s knee replacement.  Research show that differences in bone shape affect the way a knee replacement fits.  PSI uses MRI to capture the true anatomy of the patient’s knee to computer-generate a detailed surgical plan, including customized instrumentation that shows exactly how the new knee should be placed. The computer technology aligns all the cuts made in the bone, and thus perfectly aligns the knee replacement.

The patient specific instruments were developed based upon the clinically proven principles of mechanical axis alignment. For example, in total knee replacement, proper alignment is a crucial factor in the function and longevity of the replacement joint. Studies show that misalignment causes increased wear of the implant and can lead to premature failure.
