Services: Mako Total Knee Application
Shady Grove is proud to be the only Hospital in your region offering this new treatment option. Mako Total Knee transforms the way total knee replacements are performed. The Mako Total Knee application is a knee replacement treatment option designed to relieve the pain caused by joint degeneration due to osteoarthritis. Through CT-based 3D modeling of bone anatomy, surgeons can use the Mako System to create a personalized surgical plan and identify the implant size, orientation and alignment based on each patient’s unique anatomy. The Mako System also enables surgeons to virtually modify the surgical plan intraoperatively and assists them in executing bone resections.

Dr. Peterson assessed my knee injury and explained my options. Very professional!
I had an appointment with Dr. Peterson in April 2026. He was clearly an expert and great at communication with my path forward. Super nice person also!!! After a cortisone shot to my knee - 90% of my pain vanished by the time -I had checked out.
Don’t discuss symptoms just prescribes surgery
He’s the best!
I was incredibly impressed by your team of young women; they were friendly, engaging, and handled customer service flawlessly. I did, however, find my first interaction with Dr. Mark Peterson to be very impersonal. He seemed overwhelmed and rushed me through our interaction. I think the overall customer experience could be improved if that role reflected the same welcoming approach as the rest of the team."
He spoke with me for 2 minutes, did not address my concern, told me to do physical therapy and sent me on my way. Worst experience.
Dr. Peterson and his staff were very professional, knowledgeable and very friendly. The office was clean and spacious. Dr. Peterson listened to my concerns and was able to offer me great care.
Doctor Mark A Peterson, he's professional, kind he explain to you if you have any question, He's excellent Doctor.
I have been a patient of Shady Grove Orthopedics for about 40 years. This was the first time I had an appointment with Dr. Peterson. I was seeing him for a problem with my knee for which I had seen a doctor 6 weeks earlier but was not satisfied with the results. Dr.Peterson was amazing! He explained EVERYTHING that was happening with my knee and the reasons it was not any better. I was now able to understand what / why was happening with my knee. He detailed a procedure he is going to do and how it will improve my knee and will be MUCH more effective than the “ staying off it” for 6 weeks that the first doctor I saw had told me to do. I left the appointment feeling so glad I had driven the 45 minutes to come to Shady Grove Orthopaedics and see Dr. Peterson . He did everything you want a doctor to do…. explained things thoroughly, answered all my questions , and made sure I was comfortable with the proposed treatment.
I left his office feeling so much better!
