For forty years, Chicago filmmaker and inventor Jerry Vasilatos struggled with the painful reality of a conventional prosthetic leg. Following a near fatal train accident at age 20 that resulted in the above-knee amputation of his right leg, Vasilatos found that using a suction-socket prosthetic was incredibly uncomfortable, opting to use crutches or a wheelchair for most of the week. For a man with the ambition and energy of Vasilatos, who is an award-winning filmmaker, media producer and inventor, the limitations were more than physical. They were a ceiling on everything he wanted to do.
But in early 2025, Vasilatos pursued a life-changing medical breakthrough called osseointegration (OI) that he had discovered through his own independent research. He became the first patient in the City of Chicago to undergo a compress-fit OI procedure at Northwestern Medicine, performed by orthopedic surgeon Dr. Terrence Peabody as part of an FDA clinical trial. The procedure involves surgically implanting a titanium post directly into the bone of the residual limb, thus eliminating the socket entirely. Vasilatos’s prosthetic leg now attaches directly to his skeletal system in under ten seconds.

Working with prosthetist Mike Socie and the rehabilitation team at the Shirley Ryan AbilityLab — ranked the number one rehabilitation hospital in the United States — the results have been transformative. On April 2nd, WGN-TV’s Medical Watch aired a feature on his one-year anniversary with the procedure, reported by Dina Bair and Katharin Czink. The segment, which can be viewed at wgntv.com, brought his story to a citywide audience and helped shine a spotlight on a procedure that most Chicagoans, and most Americans, have never heard of.

“Before, if I put my cane aside you would see my body wobbling and it would be painful to walk for long periods” Vasilatos shared. “Now it’s like I’ve gotten my real leg back. The stability, the comfort, it’s just amazing. I want other amputees, other limb loss survivors to know about this.”
At his recent 60th birthday party in March, Vasilatos walked around for hours without assistance — something unthinkable just a year earlier prior to his procedure.
Born and raised in Chicago by his Greek-American family, Vasilatos has long channeled personal adversity into innovation. His father, A.J. Vasilatos, is his co-inventor on the SandPad EasyWalk Stabilizer, the patented cane and crutch accessory he conceived on a napkin after facing challenges in 2003 crossing the beach in Greece on his crutches. That invention, brought to market together with his father, now holds utility and design patents across seven international markets earning innovation nominations and awards as well as five star reviews on Amazon. It was that same spirit of problem-solving that led him to osseointegration, and to his mission of making sure no other amputee has to search as long and as hard as he did to find it.

Despite being standard practice in Australia and across the European Union for over a decade, OI remains largely unknown in the United States, where it is still undergoing FDA clinical trials. When Vasilatos first inquired about the procedure at one of Chicago’s major medical centers, their orthopedics department had never heard of it. He found Northwestern Medicine at the forefront of the innovation through a Google search.
“Most amputees and many of their doctors have never heard of osseointegration,” Vasilatos says. “That is the problem I am trying to solve.”
Now, as a filmmaker, media producer and limb loss advocate, he is doing exactly that. He has been documenting his entire OI journey on his YouTube channel and website, building a public resource for the estimated 2.1 million Americans living with limb loss, 185,000 of whom lose limbs every year.
April is Limb Loss and Limb Difference Awareness Month in the United States, and Vasilatos has dedicated this month to reaching as many amputees, families, and physicians as possible with a simple message: this option exists, it works, and you deserve to know about it.
The FDA clinical trial for osseointegration remains open and is actively seeking participants in Chicago. For any amputee who has struggled with conventional socket prosthetics, this trial represents a potential path to a fundamentally different quality of life.
