My big thing right now is reducing fluid in the knee.  It only gets aggravated after playing sports as the surgeon and PT both said would happen for a while.  I did work on running mechanics during PT.  I am just trying to find additional help to keep knee swelling down from post-op Meniscus surgery.  Marc Pro states on their page the device is not intended for medical use, but in one of the videos posted above, Marc did mention he used it to reduce swelling in his collar bone area.  I am trying to find people that have had similar problems and what their methods were to reduce knee joint swelling.
