That was interesting and neat to do the 'virtual knee surgery' (no blood galore either in case a few might shun away from trying it), although, there wasn't any captions, yet there were small pop-ups of steps to initiate which is helpful for those who cannot hear the virtual knee surgery procedure. Thanks for the link Nancy--
Did you know that when you click on "Subtitles" on the top right corner where the doctor was talking to you....it provides captioning of what he said? Just letting you guys know. Glad you like it.
