Medical Center. He completed his orthopedic surgery residency at Lutheran Hospital of Indiana and is a Fellow of the American College of Surgeons and the American Academy of Orthopaedic Surgeons.

WHAT OUR PATIENTS ARE SAYING
I just wanted to take an opportunity to thank you greatly for the service you provided for me. It has been amazing the improvement I am experiencing. A while back before I knew it was a hip problem I guess I felt it was all the aging process and I was wondering with the deterioration in my abilities etc how I would be in another 5 years.
- Total Knee Patient
I have been very active my entire life. A couple of years ago I started having problems with my knee. I live about an hours away from Dr. Klaassen’s office and did not know much about him. When I started to ask around who I should see, I was surprised to hear the recommendation for Dr. Klaassen. Everyone was right.
- Total Hip Patient
The surgeon, Dr. Mark Klaassen, did a marvelous job on my partial knee (right). After 6 weeks what a positive difference in pain. Much less pain. The staff were terrific and very helpful as well as knowledgeable. OSMC is a fabulous place to have your knee surgery done. “All these medical people care about patients here”and all of them have PATIENCE with us ornery PATIENTS. Thank you Dr. Klaassen and thank you team!
