He was very helpful in explaining what was seen on the X-ray and actually cared about how to address the problem .
I am very happy to move forward with the necessary test to address this problem. I look forward to our follow-up appointment and the plan to fix the problem.

He listened intently and suggested a treatment option that might help rather than going first to the most radical option.

Dr Merrell is very personable and was informative in explaining what the knee issue was after seeing the X-ray. He further explained the options available for treatment, and will follow up with an MRI to further evaluate. In the meantime, the cortisone injection he did soon gave remarkable relief.

Dr. Mark R. Merrell, M.D., is board-certified in orthopaedic surgery and is a member of the American Academy of Orthopaedic Surgeons. He specializes in surgical and non-surgical treatment of the hip, knee, and shoulder (including joint replacement).
Dr. Merrell grew up working in the potato fields of eastern Idaho but developed an early interest in the medical field. After sustaining several injuries himself, he became interested in how the body works and heals. He wanted to be an orthopaedic surgeon from the time he was 12 years old.
After practicing in the Tri-Cities for over 25 years, one of his greatest satisfactions is seeing his patients' improvement after treatment (whether that be surgical or non-surgical).
