Hip and Knee Reconstruction


Dr. Groover is fellowship-trained in adult hip and knee reconstruction. He obtained his undergraduate degree at the University of Wyoming, where he played defensive end for the football team. He completed medical school at the Lake Erie College of Osteopathic Medicine and orthopedic surgery residency at Grandview Medical Center in Dayton, OH. In 2018 he was awarded the Osteopathic Orthopedic Resident of the year by the American Osteopathic Foundation. He completed the prestigious adult hip and knee reconstruction fellowship at the Cleveland Clinic in Cleveland, OH.

Dr. Groover is board certified by the American Osteopathic Board of Orthopedic Surgery and is affiliated with the American Osteopathic Academy of Orthopedics, Montana Medical Association, American Association of Hip and Knee Surgeons.


The focus of Dr. Groover’s practice is the treatment of hip and knee arthritis with minimally invasive, rapid recovery total hip replacement, partial (unicondylar) knee replacement, total knee replacement, and kinematically aligned total knee replacement. He is specialty trained in revision hip and knee replacement with a focus on the treatment of infection, implant failure, and complications from trauma and severe deformities.

His philosophy in the treatment of adult hip and knee conditions includes designing a treatment protocol that helps patients keep their own hips/knees functioning as well as possible. When performing joint replacements he offers a variety of techniques so he can tailor treatment to each patient.

Dr. Groover did an exceptional job performing my total hip replacement surgery. The recovery process was much quicker than expected and my incision is healing wonderfully. I would recommend Dr. Groover without question.
