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.

We have had 5 knee surgeries in my family over the last 30 years with Ortho MT. I myself have had severe hip pain for 9 years - I am 54 years old - I met Dr. Groover at Ortho MT Miles City facility in June - he did a hip replacement on me in September and it has changed my life! I am pain free for the first time in 9 years and I have my life back! I can chase around my grandkids and get back to the business of normal day to day life without pain. It is a game changer for me and for my family. Dr. Groover and his staff are wonderful, caring people and I give them and Ortho MT my highest recommendation. Thank you from the bottom of my heart! Of all the bad things happening in 2020, this is something good I will never forget!
