The MSK Cornerstone Course Orthopedic Surgery review was created to provide an in depth, structured, and convenient learning tool for orthopedic surgeons and musculoskeletal medicine providers. This audio lecture course is broad in scope, teaching the fundamentals and concepts that drive the practice of orthopedics, while emphasis is also placed on the frequently tested material found on orthopedic surgery qualification examinations. This is not "teaching the test", this is teaching the fundamentals of orthopedics..... with testable material highlighted.
