Understanding Arthroplasty Hips: Can They Get an MRI?

As a seasoned orthopedic physical therapist with over forty years of experience, I’ve seen the landscape of hip arthroplasty evolve significantly.

The first total hip surgery I observed was in 1975, just after graduating from physical therapy school. Back then, the entertainment industry produced medical-oriented TV series, like Ben Casey and Marcus Welby, MD.

In those TV episodes, everything was very serious and precise in the operating room.
Imagine my surprise when everything was exactly as portrayed in those TV programs until the patient was totally anesthetized, then the rock-n-roll music was brought up, the Black and Decker drills were brought out, and the hammer and chisels made their appearance!

This was a total hip revision, and the surgery took slightly more than three hours.
I was scheduled to see the patient the following morning to begin physical therapy, and I thought to myself, “This guy isn’t going to get out of bed for weeks!”

Much to my surprise, upon visiting the patient bedside the following morning, I was greeted by a happy, cheerful patient ready to get out of bed and start walking with his walker.
He stated, “This is the best my hip has felt for a long time.”

Over the past forty years, I have seen the progression of techniques, surgical time, and hip prosthesis materials that now allow imaging with MRI, an imaging technique that was in its infancy in 1975.

The question can hip replacements withstand the intricate process of an MRI has often surfaced among patients with hip implants.
