OSI is the first in Northeast Wisconsin to offer Mako robot-assisted total joint surgery, the latest advancement in robotic technology. This new surgical approach to joint replacement offers a higher level of customization and precision for implant alignment and positioning.

How does the Mako Robot-Assisted Total Joint Surgery work?

  • Dr. Obma can create a patient-specific 3-D plan that uses a CT scan to guide the reconstruction
  • The personalized 3-D plan takes into account each patient’s specific anatomy and ligament balance
  • During the operation, Dr. Obma uses the robotic arm to assist in performing the surgery
  • The surgeon guides the robotic arm within the predefined area, and the robotic arm technology helps the surgeon stay within the planned boundaries


After surgery, experience a stay at Recovery Inn, located right at OSI’s Appleton campus. Recovery Inn is a five-star hotel like experience that provides personalized care to ensure your complete healing. Click Here to Learn More About Recovery Inn.


“Dr. Obma is very helpful, great at answering questions, definitely cares for his patients. Understands how you want to get back to doing the things you love (ie gymnastics for me). He did an amazing job on my knee surgery and when I left an hour after surgery I was already slowly walking.”

“Dr. Obma met with me after I injured myself at work. I went through months of physical therapy with no success. Dr. Obma tried everything before we finally agreed on surgery. He was absolutely amazing, extremely kind and helpful in all aspects. Thank you so much Dr. Obma, you truly are amazing!”

“Dr. Obma is an excellent surgeon, one of, if not the best in Green Bay. With that being said, what really stands out about him is his bedside manner. He really cares about the whole person and will sit and talk with you like you’re his only patient for the day.”

“Everything was great from start to finish. I’m less than 4 months after surgery and I hardly feel like I ever had it to begin with. I’m absolutely amazed by the quality of work and the speed of which I’ve rehabilitated.”

“Dr. Obma is by far the best orthopedic that I’ve ever seen. Not only is he extremely knowledgeable, he’s also very personable. Seeing him is more like seeing a good friend who just happens to be an orthopedic. I wouldn’t trust anybody else with my knees!”

“Dr Obma did an excellent job repairing my knee. His knowledge and experience combined with an ability to talk to me in terms that I can understand make him a top choice for orthopedic care in the Green Bay area!!”

“Dr. Obma was everything I hoped for in an Orthopedic expert. Two previous Orthopedic doctors suggested knee replacement without even ordering a scan. Dr Obma ordered a scan and found my osteoarthritis was advanced enough to take this major step. He was very thorough and took the time to explain everything in detail. Right now we’re trying injections with an exercise program to strengthen my knee. He could have easily rubber stamped the replacement solution but did what was right for me.”
