UF Health Medical Group Orthopaedics & Spine

At UF Health Medical Group Orthopaedics & Spine, five cutting-edge physicians bring together decades of specialized expertise to provide comprehensive, patient-centered care throughout Lake, Sumter and Marion counties. Together, this powerhouse team represents the best of orthopaedic and spine care—local, skilled and united in one mission: helping patients be at their best. 

Dr. Isaac Mitchell, a familiar face in the Leesburg community since 2003, is a fellowship-trained, leading specialist in sports medicine and advanced shoulder care. “I live here, my kids go to school here — I’m invested in helping this community thrive, both in and out of the clinic,” says Dr. Mitchell, who also mentors local students with an interest in medicine. 

Dr. Cedric Tankson, a dedicated expert in foot and ankle care, specializes in the comprehensive treatment of complex conditions affecting the lower extremities. “There are certain illnesses you can only manage, but with orthopaedics, you can help someone return to how they were before their injury. That’s one of the things that attracted me to the field,” he says. 

Dr. Jon Radnothy brings more than three decades of trusted orthopaedic expertise to UF Health, specializing in robotic joint replacements of the hip, knee and shoulder. Before joining the organization in 2023, he built and led a thriving practice, earning a reputation not only for his clinical excellence but for his unwavering dedication to patient care and community service. “Patients come in for their one-year follow-up and are so fired up because we not only restore a hip or a knee, but their lives,” he says.  

Dr. Paul A. Mahle is a fellowship-trained orthopaedic surgeon specializing in minimally invasive and robotic hip and knee replacements, including complex revision surgeries. A Central Florida native, he joined UF Health about six months ago. “It’s incredibly rewarding to see patients go from pain and limitation to walking, golfing and enjoying life again,” he says. 

Rounding out UF Health’s comprehensive orthopaedic and spine care team in central Florida is the recent addition of Dr. Ali Zarezadeh, a fellowship-trained spine surgeon and UF graduate. He specializes in common and complex spine conditions — including degenerative disease, deformity, tumors and traumatic injuries. “My goal is to take away pain and help patients stay active and independent, doing what they love for as long as they can,” he says. 

Over the past year, UF Health has responded to the growing community needs by assembling a dynamic team of orthopaedic and spine experts. With deep local roots and advanced expertise, this powerhouse group will continue to deliver exceptional care and lasting impact across the region.
