About 2, 6,12, and 24 weeks after surgery, you will have standard follow-up visits which will include the same surveys and physical therapy measures described above. However, at Weeks 3, 7, 13, and 25 you will use a mobile device to send the study staff photos of your surgical wound and video of you walking. These updates will help your doctor to check your recovery. The photos you will take will only be of a small area of skin near your wound.
