Every patient deserves time, attention, and clear communication. I make it a priority to explain each step of the process so my patients know exactly what to expect—before, during, and after surgery.

After a failed shoulder replacement performed elsewhere, Kris was still dealing with pain and limitations that impacted his daily life.

We performed a revision surgery, converting his failed anatomic shoulder replacement to a reverse shoulder replacement. Now, just 12 weeks later, Kris is feeling significantly better and getting back to the activities he enjoys.

We’re grateful to be part of his recovery journey and look forward to seeing his continued progress.

The goal of a knee replacement is not just pain relief. It’s restoring natural movement.

I use a spherical implant design that more closely recreates the knee’s natural anatomy and movement. By restoring normal kinematics, the result is a knee that feels more stable, more natural, and better aligned with how the body is meant to move.

Precision matters, because function matters.

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.

Before surgery, knee pain made even simple things difficult for Lisa. Walking, standing, exercising, and horseback riding became harder and harder to enjoy.

After having both knees replaced, she’s back to doing the things she loves without the constant pain holding her back.

Seeing patients return to the activities that bring them joy is always the goal.

There are two approaches to shoulder replacement. An anatomic replacement keeps the ball and socket in their natural positions, but it doesn’t address certain soft-tissue problems, especially when the rotator cuff isn’t functioning the way it should.

A reverse shoulder replacement switches the mechanics, placing the ball on the socket side and the socket on the arm bone. It’s a strong option for relieving pain and restoring stable, reliable motion.

If you’d like to schedule an appointment to discuss your shoulder and learn more about your treatment options, give us a call at 440-709-1945.

Today, my team and I performed an elbow extensor tendon repair, a procedure that restores the tendon responsible for extending the elbow and stabilizing arm movement. By carefully reattaching the tendon, the goal is to relieve pain, restore strength, and support a smooth recovery.

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.
