As we celebrate our 2 year anniversary we are releasing for the first time our KOOS knee pain data ( knee osteoarthritis outcome score ) for mild , moderate and severe knee osteoarthritis. These graphs show the astonishing improvement our typical arthritis patient enjoys. We continue to follow our study patients closely and see no evidence of osteoarthritis progression in those patients who use the AcuKnee on a regular basis. We will periodically be posting long term updates on these patients.
