An orthopedic surgeon is a medical doctor who specializes in diagnosing and treating problems related to the musculoskeletal system. This system includes bones, joints, ligaments, tendons, and muscles. Orthopedic surgeons help patients with injuries, such as fractures, and conditions like arthritis, ensuring they can move comfortably and maintain an active lifestyle. These surgeons use various methods to treat issues, including surgery, physical therapy, and medication. They may perform operations to repair broken bones or replace damaged joints, such as in a knee replacement. Their goal is to restore function and relieve pain, helping patients return to their daily activities.
