Two joints. One goal. Getting back to living life comfortably.

Elaine underwent a same-day discharge hip replacement using a direct anterior approach with a bikini incision, followed by a complex revision knee replacement to address a failed implant that had become unstable. By removing the prior hardware and restoring stability with a new knee, we were able to get her back on a safer, stronger path forward.

Grateful to be part of her journey and to see her moving forward with confidence.

Lonnie shares how being prepared for recovery and supported by a great team made the entire process smoother.

An experience that goes beyond just surgery.

My team and I are grateful to see his journey go so well and to know he’s happy with his outcome. That’s exactly why we do what we do.

Sometimes the decision is simple. We asked Lonnie what made him move forward with a partial knee replacement.

He shares it came down to knowing a full knee replacement wasn’t necessary. If part of the knee is still healthy, there’s no reason to replace it.

As he put it, “why fix something that isn’t broken?”

Stay tuned for more from Lonnie’s story.

Trust matters, especially when it comes to surgery.

Lonnie shares how everything was explained to him upfront. What was wrong, how it would be fixed, and what to expect. And most importantly, that a full knee replacement wouldn’t be done unless it was truly necessary.

Stay tuned for more from Lonnie’s story.

His only regret? Not doing it sooner.

Before surgery, even simple movements were painful for Lonnie. He injured his knee getting into his car, and a torn meniscus combined with underlying arthritis made everyday activities difficult.

Following a partial knee replacement, he’s now moving with less pain and getting back to the things he enjoys.

Hearing patients describe where they started makes the outcome that much more meaningful.

Stay tuned for more from Lonnie’s story.

Grateful for the trust my patients place in me. It’s an honor to help them get back to doing what they love.

Every patient deserves to feel heard, informed, and confident in their care. That’s why I take the time to listen, explain, and do things the right way.

Smaller, hidden scar. Minimal muscle trauma. Faster recovery. That’s the power of the bikini incision for hip replacement.

Using an anterior approach, this technique goes between muscles instead of cutting them—resulting in less pain, less downtime, and a scar that’s both lower and easier to conceal.

It’s a patient-favorite for a reason.

If you need an appointment to discuss a hip replacement and would like to learn more about the bikini incision, give us a call. 440-709-1945

When patients come in for hip replacement, the goal is simple: get back on your feet faster, with less pain and a smaller scar.

How do we make that happen? By using the AMIS technique and a special “bikini” incision, a minimally invasive approach that avoids cutting major muscles, promotes quicker recovery, and leaves a scar that’s lower and more discreet.

It’s a better and more innovative approach to hip surgery that puts healing, and you first.

Another day in the OR dedicated to precision, preparation, and teamwork.

My team and I performed a total knee replacement using the muscle-sparing, subvastus approach. This technique minimizes disruption to surrounding muscle and helps patients begin moving sooner with greater comfort.

If you’d like to schedule an appointment to discuss knee replacement options, give us a call at 440-709-1945.
