What is a one-sentence summary of the following article?
After you have completed your residency, you are licensed to practice medicine and surgery as an orthopedic surgeon. The final certification that you will need to obtain is passing the orthopedic board exam, which you can apply for after you have been in practice for 2 years. This exam is usually taken while students are still in their residencies and have both written and oral components. The U.S. Medical Licensing Examination (USMLE) and/or the Comprehensive Osteopathic Medical Licensure Examination (COMLEX) are required in order for orthopedic surgeons to legally practice medicine. The exam contains three steps and evaluates a doctor’s aptitude for being a doctor, including knowledge, concepts, and principles.  Each step of the exam has a different fee, costing $70, $600, and $1,275  for different components.  This is the general licensure exam that all doctors must take. In order to become licensed as an orthopedic specialist, surgical residents must also pass the American Board of Orthopedic Surgery (ABOS) and/or the American Osteopathic Board of Orthopedic Surgery (AOBOS) exams. These exams ensure the safe practices of orthopedic surgeons in the U.S. The exam is called Maintenance of Certification (MOC) and has four sections.   Fees for the exam are over $1,000, with a late fee of $350. This test is required again every 7 to 10 years.

Summary:
Study for the licensing exam. Pass the Medical Licensure Boards. Pass the board certification exam.
