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!
