Orthopaedics

Specialized Orthopaedic Care, Close To Home

Orthopedics focuses on injuries and diseases of the musculoskeletal system, including bones, joints, ligaments, tendons, muscles and nerves. If you break a bone in Mahaska County or need a knee replacement in Oskaloosa, you’ll meet our orthopaedist, Dr. Jon Gehrke, MD. 

Michael Johnston, PA-C, joined the department in 2010 to expand access for orthopaedic care to the community. Mike has more than 20 years of experience in bone and joint health, previously practicing at the VA Hospital in Des Moines.
