User Reviews

AO Surgery Reference is a free, highly practical reference for orthopedic and maxillofacial procedures. Users praise its quick, concise, well-illustrated content and usefulness in the operating room and for students. However, common downsides include incomplete coverage, lack of offline access, limited iPad support, and occasional stability issues. Users also want more updates and expanded modules (hand, mandible, skull base). Overall, strong value with notable room for expansion.

Pros

Very useful reference for orthopedic and maxillofacial surgical approaches, including long bone and facial fractures.
Free to use, offering substantial value at no cost.
Concise, well-illustrated content that's quick to consult for quick reviews or pre-case prep.
Highly educational for students and residents, with detailed procedural content.
Broad, practical content that is helpful for planning and teaching across topics.

Cons

Incomplete coverage with missing chapters/categories (e.g., pelvic ring, upper limb, mandible, skull base) and ongoing content gaps.
Lack of offline access/download and reliance on online connectivity.
Not fully optimized for iPad; users request an iPad version.
Occasional stability/startup issues such as blank screens on launch or after updates.
Requests for more frequent updates and expanded modules (e.g., hand module, additional categories).

Recent reviews

App is excellent for surgical approaches, both long bone and facial fractures. Recently, app had issues with new iPhone update, but these have been resolved. Very good reference, especially being free.

This is a great app when it’s working however, lately whenever I open it, nothing happens and I’m looking at a blank white screen.

I'm seriously impressed by the way this app works, it's a huge benefit for any orthopaedic surgeon who is about to deal with a variety of cases after stepping in to operation theatre each morning, surgeons might already know most of the stuff present here but still they can over look in many situations. This app helps in restoring what is to be there in your might at this particular moment, and all this is done by AO' in other words what they decide dictums in orthopaedic world.
