3D virtual knee models promoting Arthrosurface products.
Arthrosurface has released this app presumably for patient education and demonstration of normal and abnormal knee kinematics. The app is very simple and opens directly to the 3D image of their knee model. Finger swipes allow for either 360 degree rotational manipulation or range of motion. There are 3 views: normal, disease, and surgery. You can also elect to view the implant alone. Overall, the app is limited in functionality and as a demonstration of knee motion and implants, there are other apps with a much greater feature set.
