As a mid 50's veteran of many marathons, three knee surgeries and now pain and swelling (right knee) after every attempt to run I believed my running days were over. To my regret my workouts had moved to the exercise bike. Saw Dan in June 2018 for an assessment. We did three things, assessed my running style by video, he recommended a change of running shoe and a set of exercises. We made adjustments to my running gait and posture which took some remembering on treadmill, but are now natural. I now see Dan every six weeks for review and assessment. I have been running again up to ten miles a go ( and up to 40 miles per week) with no pain or swelling. I still can't believe it to be honest based on where I was at and had been told by a consultant knee surgeon at the Nuffield to give up thoughts of running. I am the most cynical person in the world, but I know I am only running again as a consequence of this intervention. Even if I break down again tomorrow (no prospect at the moment as knee is great) I have had another 17 months of running I would not have had were it not for the changes made. I am truly grateful and would not have believed this was possible.
