Sarah McDonald’s Story: Finding Answers, Restoring Confidence, and Getting Her Life Back

For years, Sarah McDonald knew something wasn’t right.

An active educator, former collegiate athlete, fitness instructor, and someone who simply loved being outdoors, Sarah expected life to slow down after knee replacement surgery but not stop altogether.

Instead, after her first knee replacement at age 47, the pain only worsened.

“I was miserable,” Sarah recalled. “My knee was constantly swollen, hot to the touch, and painful. I hated getting out of bed.”

Over the next several years, Sarah underwent a second surgery, countless tests, multiple procedures, and appointments with specialists. She was evaluated for infections, had fluid drained from her knee repeatedly, and searched for answers while trying to continue teaching and living her life.

“I knew something was wrong,” she said. “But I kept being told everything looked fine.”

Eventually, additional testing revealed what no one had previously suspected, a severe nickel allergy. The implants from her previous surgeries contained nickel, and her body was reacting to them.

While the diagnosis finally explained her symptoms, finding someone willing to help wasn’t easy.

After moving to Tennessee, Sarah met with several surgeons, but none were willing to perform another revision using a nickel-free implant.

Feeling defeated, she returned to Ohio hoping someone would finally listen. That’s when family members recommended Dr. Brian Cohen.

From the very first appointment, Sarah felt something she hadn’t experienced in years, confidence.

“He was just real,” she said. “He talked to me in normal terms, listened to everything I had to say, and was confident he could help me.”

Dr. Cohen thoroughly reviewed her history and recommended a second revision using titanium implants instead of nickel-containing components.

In April 2025, Sarah underwent her third knee surgery. This time, everything changed.

Only weeks into recovery, Sarah noticed a remarkable difference. For the first time in years, her knee wasn’t constantly swollen or painful.

“I haven’t felt this free or this mobile in years,” she said.

Physical therapy has gone well, her range of motion continues to improve, and she’s already back to driving and returning to everyday activities with significantly less pain.

“I just wanted to hug him,” Sarah said of seeing Dr. Cohen after surgery. “He restored my confidence and my mobility.”

For someone who once taught aerobics and cardio drumming, movement has always been part of who Sarah is.

Years of pain forced her to give up many of the activities she loved, including running, exercising, gardening, and even walking her dog.

Now, she’s excited to embrace a new chapter. Rather than returning to high-impact exercise, Sarah is looking forward to walking her dog again, biking, spending time in her flower gardens, reading outside, and exploring Pilates as she continues to rebuild her strength.

“I just want to get back to low-impact fitness and being outside again,” she said.

After three knee surgeries, Sarah admits she was once self-conscious about the scar that runs down her knee. Today, she sees it differently.

“Scars aren’t flaws, they’re proof of your strength.”

That perspective reflects the resilience she’s developed throughout her journey. Despite years of setbacks, unanswered questions, and discouragement, Sarah never stopped searching for answers.

Sarah now gives Dr. Cohen’s name to friends and family who are searching for orthopedic care.

“He is very patient with you, and he actually listens.”

Looking back, she’s grateful she found a surgeon willing to take on the challenge when others wouldn’t.

“He was the one who finally listened to me and got me on the right path to having a better quality of life at 51.”

For Sarah, the biggest victory isn’t simply having another successful surgery.

It’s getting her life back.
