Dr. Obma is fellowship trained in sports medicine through the world famous Andrews Institute. He uses leading-edge techniques, technology and treatments for each and every patient.


Your knee is made up of many important structures, any of which can be injured. The most common knee injuries include fractures around the knee, dislocation, and sprains and tears of soft tissues, like ligaments. In many cases, injuries involve more than one structure in the knee.

Pain and swelling are the most common signs of knee injury. In addition, your knee may catch or lock up. Many knee injuries cause instability — the feeling that your knee is giving way.


Common injuries treated for the knee and ankle include but are not limited to:

  • Fracture
  • Cartilage Injury
  • Meniscus Tear
  • Ligament Tear
  • Dislocation
  • Arthritis


Knee arthroscopy may relieve painful symptoms of many problems that damage the cartilage surfaces and other soft tissues surrounding the joint. Common arthroscopic procedures for the knee include:

  • Removal or repair of a torn meniscus
  • Reconstruction of a torn anterior cruciate ligament
  • Removal of inflamed synovial tissue
  • Trimming of damaged articular cartilage
  • Removal of loose fragments of bone or cartilage
  • Treatment of patella (kneecap) problems
  • Treatment of knee sepsis (infection)


“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.”
