Orthopaedic Resources for Patients

Orthopaedics is the medical specialty that focuses on injuries and diseases of your body's musculoskeletal system. This complex system includes your bones, joints, ligaments, tendons, muscles, and nerves, and allows you to move, work, and be active.

We are providing the following resources to help you have the best orthopaedic health possible:

OrthoInfo is a trusted source of information about musculoskeletal conditions and injuries — how they are treated, as well as how they can be prevented. The articles and videos are developed by orthopaedic surgeons who are members of the American Academy of Orthopaedic Surgeons (AAOS). All of the content on the website is peer-reviewed by physician members of the OrthoInfo Editorial Board who are experts in their fields.

Orthopaedic vs Orthopedic

Ever wonder why you sometimes see orthopaedics spelled differently? The word “orthopaedics” comes from the Greek root ortho (straight) and pais (child). On the other hand, the word “orthopedics” contains the Latin root pedis (foot). Rather than limiting all procedures to only the feet, AJRR prefers to include all procedures and stay with the traditional Greek roots. Most medical groups choose to remove the “a” from orthopaedics, however, the majority of the orthopaedic community, including AJRR, chooses to stick with the traditional spelling. Even though organizations and spell check may not agree, both spellings are technically correct!

Facts and Figures

Considering the number of ‘baby boomers’ reaching old age in the U.S. along with the prevalence of osteoarthritis and the growing obesity epidemic, it is expected that by 2030 there will be approximately 3.48 million total knee replacements and 572,000 hip replacements performed annually (Kurtz et al, 2007).

There are 719,000 total knee replacements and 332,000 hip replacements performed annually in the U.S. (data from the Centers for Disease Control and Prevention (CDC). This number will grow exponentially expediential with a more active and aging population.)

  • More than 7 million people in the U.S. have had a knee or hip replacement surgery
  • Hip and knee devices account for more than 85% of the joint reconstruction and replacement market
  • Joint registries demonstrate up to a 50% reduction in revision rates after registry initiation and identification of best practices
  • If the U.S. revision rates were cut by just 2%, Medicare could realize savings of over $65 million
